SSD Power Loss Recovery

SSDs store the active copy of their Flash Translation Layer in volatile DRAM cache for speed. During a graceful shutdown, the controller flushes this DRAM cache to non-volatile NAND. A sudden power loss interrupts that flush. The mapping table is lost or partially written, leaving the controller unable to locate your files on the NAND.

• ●Drive reports 0 bytes total capacity or shows incorrect capacity (e.g., 2TB drive reads as 8MB)
• ●Drive shows as "SATAFIRM S11" or an unfamiliar model name in BIOS
• ●Drive not detected in BIOS or Device Manager
• ●Drive is detected but hangs, causing the system to freeze when accessed
• ●Drive enters read-only mode or reports "write protect" errors
• ●Computer refuses to boot from a previously functional SSD after a power event

A power surge adds a second failure mode: the surge overwhelms the Power Management IC (PMIC) and TVS diodes on the SSD circuit board. The PMIC burns out, cutting power delivery to the controller. The NAND flash retains its electrical charge and data. Board-level repair restores the power path.

SSD power loss recovery costs $200–$1,500 for SATA drives and $200–$2,500 for NVMe drives. The final price depends on whether the failure is purely firmware (FTL corruption) or also electrical (blown PMIC from a surge). Every case starts with a free evaluation and a firm quote. If we recover nothing, you pay nothing.

A donor drive is a matching SSD used for its circuit board. Typical donor cost: $40–$100 for common models, $150–$300 for discontinued or rare controllers. Rush service available: +$100 rush fee to move to the front of the queue.

The Flash Translation Layer maps logical block addresses (LBAs) from the operating system to physical page addresses on the NAND flash. Because NAND cannot be overwritten in place, this mapping changes with every write operation as the controller redistributes data across cells for wear leveling and garbage collection.

For performance, the active FTL lives in the SSD's DRAM cache. During a graceful shutdown, the host sends a Standby Immediate command and the controller flushes the DRAM contents to a reserved section of NAND called the service area. An unexpected power loss (also called asynchronous power loss or surprise power loss) terminates this sequence mid-flush. The service area receives a partial or inconsistent copy of the mapping table. On the next boot attempt, the controller reads the corrupted service area, cannot parse the FTL, and enters a safe mode or hangs in an initialization loop.

The user data on the NAND flash cells is not erased by this event. NAND cells retain their electrical charge for months to years without power (JEDEC rates consumer SSDs for 52 weeks of unpowered retention at 30C). The data is stranded because the map to find it is broken, not because the data itself is gone. PC-3000 recovery reads the raw NAND pages, extracts surviving page headers and block sequence numbers, and assembles a virtual translator in the recovery workstation's RAM to restore logical file access.

Enterprise SSDs and consumer SSDs use different strategies to handle sudden power loss. Enterprise drives include hardware capacitors; consumer drives rely on firmware. The protection level determines how much data survives an outage.

Enterprise drives with aging PLP capacitors can still suffer FTL corruption if the capacitors no longer provide sufficient hold-up time. Sustained high operating temperatures in dense server racks accelerate capacitor degradation. A drive rated for 20ms of hold-up power at manufacture may deliver only 5ms after several years, which is insufficient to flush a full DRAM cache.

Consumer SSDs write incoming data to a fast pseudo-SLC (pSLC) cache where the controller programs just 1 bit per cell. During idle periods, the controller "folds" this cached data into denser TLC or QLC blocks. Power loss during a fold operation corrupts the FTL journal's block sequence counters, causing the controller to enter panic mode on the next boot.

Folding compresses roughly 3 SLC blocks into 1 TLC block (or 4 SLC blocks into 1 QLC block), creating write amplification as the controller rewrites data across NAND dies. The FTL tracks which SLC pages have been migrated & which remain valid through a bitmap in the service area. If power cuts mid-fold, the bitmap goes out of sync with the actual NAND state. Some pages exist in both the SLC cache & the partially written TLC block; others exist in neither. The controller detects this inconsistency at boot, can't resolve it, & drops off the PCIe bus or reports 0 bytes.

Drives above 80% capacity are most vulnerable. A full drive shrinks the dynamic SLC pool, forcing the controller to fold more frequently with less reserve space. PC-3000 SSD recovery reads the surviving SLC cache metadata alongside the partially folded TLC/QLC blocks, then reconstructs the mapping by reconciling both sources. Firmware recovery costs $600–$900 (SATA) or $900–$1,200 (NVMe).

Each SSD controller family implements different error-handling routines when it detects unrecoverable FTL corruption after a power event. The controller architecture determines both the error state the drive enters and the PC-3000 module required for recovery.

Phison SATA (PS3111-S11) and Phison NVMe (PS5012-E12)

Phison SATA controllers enter ROM MODE when the service area metadata is corrupted beyond self-repair. The PS3111 reports its model name as SATAFIRM S11 and shows 0 bytes capacity. The Phison E12 NVMe variant drops off the PCIe bus or locks up if power is cut during an SLC cache flush. PC-3000 injects the Phison-specific loader to access these panic states and rebuild the FTL from surviving page metadata.

Affected drives: Kingston A400, Patriot Burst, Inland Professional (SATA); Sabrent Rocket, Corsair MP510 (NVMe E12).

Silicon Motion (SM2258, SM2259, SM2262EN)

Silicon Motion controllers enter a BSY (Busy) state or drop to a generic 1GB ROM mode when the system tables are corrupted. The controller hangs on a specific initialization step and never completes SATA or NVMe enumeration. PC-3000 forces the controller past the stalled boot sequence using vendor-specific ATA commands and reconstructs the FTL from dedicated system blocks.

Affected drives: ADATA SU800, HP S700, Team Group SSDs, Crucial BX500.

Samsung NVMe (Elpis, Pascal)

Samsung NVMe controllers implement hardware AES-256 encryption with the media encryption key bound to the controller silicon. Rossmann does not currently offer in-lab firmware recovery for modern Samsung in-house controllers (Elpis, Pascal). If a power surge damages the PMIC or voltage regulators, board-level microsoldering to restore the power delivery circuit is the only viable recovery path. The original controller must boot and decrypt the NAND itself.

Affected drives: Samsung 980 Pro, 990 Pro, 970 EVO Plus.

Maxio MAP1602 / MAP1602A (Gen4 NVMe, DRAM-less)

DRAM-less Gen4 controller that depends on HMB for FTL caching. After power loss, the drive reports its raw controller name "MAP1602" with 0 bytes or 2MB capacity. Hardware AES-256 encryption makes chip-off impossible; the data is ciphertext without the original controller's key material. Professional firmware recovery tools currently lack automated FTL reconstruction support for the MAP1602; recovery relies on board-level repair to restore power delivery so the native controller can boot and decrypt the NAND itself. Rossmann does not currently offer in-lab firmware recovery for Maxio MAP1602.

Affected drives: Kingston NV2 (some SKUs), Acer FA200, Netac NV7000-T.

InnoGrit IG5236 (Rainier) Gen4 NVMe

8-channel Gen4 controller with onboard DRAM. After firmware panic, the drive reports "MN-5236" with 2MB capacity instead of its real size. Hardware AES-256 encryption binds the media key to the controller die. Professional firmware recovery tools currently lack dedicated FTL reconstruction support for InnoGrit controllers. If the controller enters the MN-5236 panic state, board-level repair to restore power delivery is the primary recovery path; the original controller must boot & decrypt the NAND itself. Rossmann does not currently offer in-lab firmware recovery for InnoGrit controllers.

Affected drives: ADATA XPG Gammix S70 Blade, HP FX900 Pro.

Phison PS5021-E21T (Gen4 NVMe, DRAM-less)

The E21T is a DRAM-less Gen4 controller vulnerable to SLC cache folding interruption. Power loss during a fold desynchronizes the block sequence counters, causing the controller to drop off the PCIe bus or enter a BSY lockup. PC-3000 SSD supports the PS5021-E21T, so once power delivery is stable the controller can be driven into its diagnostic mode to rebuild the translation layer. When power-loss damage drops the controller off the bus, board-level repair to restore power delivery comes first so the controller can boot.

Affected drives: Kingston NV2 (E21T, some SKUs).

Phison PS5018-E18 (Gen4 NVMe, premium 8-channel)

The E18 is a premium 8-channel PCIe 4.0 controller with onboard DRAM and hardware AES-256 encryption bound to the controller die. PC-3000 SSD support for the PS5018-E18 is limited to repairing-mode operations rather than full FTL reconstruction, and the hardware AES-256 binding means the original controller must boot and decrypt the NAND through its own encryption pipeline. If a power surge damages the PMIC or voltage regulators, board-level microsoldering to restore the power delivery circuit comes first so the controller can boot.

Affected drives: Sabrent Rocket 4 Plus, Corsair MP600 Pro XT, Seagate FireCuda 530.

Realtek RTS5772DL (Gen4 NVMe, DRAM-less + QLC)

Worst-case power loss combination: volatile HMB caching with QLC NAND that requires 16 discrete voltage states per cell. A system power loss obliterates the HMB FTL cache while leaving the QLC cells vulnerable to partial page programming corruption. Realtek DRAM-less controllers currently lack dedicated support in professional firmware recovery tools for automated FTL reconstruction. If the controller drops to ROM mode after power loss, board-level repair to restore the power path is the primary recovery approach; firmware-level reconstruction options remain limited for this architecture. Rossmann does not currently offer in-lab firmware recovery for Realtek controllers.

Affected drives: ADATA Legend 800.

Realtek RTS5762 and JMicron controllers appear in budget NVMe and SATA drives sold under multiple brand labels. These share firmware architectures, so a power-loss vulnerability in one brand affects all drives using the same controller silicon.

Two failure modes inside the controller account for most of the "drive disappeared," "0-byte capacity," and BSY-hang complaints we receive after a power outage. Both originate below the file system layer, which is why ordinary recovery software cannot address them: the controller never reaches a state where it can present logical sectors to the host.

1. NAND page program suspended mid-cycle

A NAND page program is a multi-pulse ISPP (Incremental Step Pulse Programming) operation. The controller issues the program command, the NAND die raises the wordline voltage in steps, and verify reads confirm each cell crossed its target threshold. If the rail collapses between the first program pulse and the final verify, the cells in that page sit at an intermediate Vt distribution: not erased, not fully programmed, and not readable through the normal sense margins. On the next power-on, the controller attempts to read the block to advance its FTL state, encounters uncorrectable ECC, and either retries forever (BSY hang) or marks the block bad and refuses to publish a capacity (0-byte report).

2. L2P table in DRAM diverged from the on-NAND journal

The active Logical-to-Physical map lives in DRAM (or HMB) for performance. The controller periodically flushes deltas to a journal in NAND service blocks so the L2P can be rebuilt at next boot. Between flushes, the in-RAM L2P is ahead of the on-NAND journal by some number of pending writes. When power drops, the RAM contents evaporate, but the host has already received acknowledgements for some of those writes. On boot, the controller replays the journal and finds physical pages it never recorded a mapping for. Some firmwares enter a safe mode (SATAFIRM S11, ROM mode, or write-protect) rather than publish an inconsistent translator.

Recovery software runs above the storage stack and depends on the controller already presenting a working translator. None of the three states above expose a translator; installing another recovery tool, running chkdsk, or reinitializing the disk in Disk Management only adds new writes that the controller misroutes, deepening the divergence. The fix has to happen inside the FTL, not on top of it.

Forensic power-up workflow at intake

When a power-loss SSD arrives, the host power path is treated as untrusted. The drive is not plugged into a motherboard until the board has been cleared. The intake sequence:

1. PMIC isolation. Host VCC pins (5V SATA or 3.3V M.2) are lifted from the rest of the board by removing or bridging the upstream fuse, fusible resistor, or input inductor. This decouples the controller and NAND from any surge-damaged downstream component before any current is applied.
2. Controlled VCC ramp from a bench supply. A current-limited lab-bench supply is connected to the isolated input rail and ramped from 0V to nominal. The current draw is logged at each step. A healthy SATA SSD draws roughly tens of milliamps at idle on the 5V rail; a board with a shorted PMIC output pulls the supply into its current limit immediately.
3. FLIR thermal monitoring during ramp. A FLIR thermal camera watches the PCB while the rail comes up. A failed PMIC, TVS diode, or output capacitor heats within seconds, identifying the failed component before the controller is powered.
4. PC-3000 SSD imaging only after the board is cleared. Once the power tree is confirmed healthy (or repaired with Hakko FM-2032 microsoldering and Atten 862 hot air rework), the drive is connected to PC-3000 SSD in the vendor technological mode. The original controller is held in a loader state while PC-3000 reads the service-area journal and rebuilds the L2P map from the surviving on-NAND entries.

SATA SSD recovery in this state is priced at $600–$900. NVMe SSD recovery is priced at $900–$1,200. If the PMIC or output capacitors are damaged and require microsoldering before imaging, board repair is priced separately at $450–$600 (SATA) or $600–$900 (NVMe). Free evaluation, firm quote before any paid work, no data no fee.

The drive interface protocol affects both the vulnerability window for FTL corruption and the complexity of recovery after a power event.

NVMe drives using Host Memory Buffer (HMB) technology are especially vulnerable. These DRAM-less drives use the computer's system RAM as their FTL cache. A system-wide power loss obliterates the HMB data along with all other system RAM contents, leaving the NVMe controller heavily reliant on firmware journaling for recovery.

A dead SSD that draws no current, or trips the host's 3.3V over-current protection on plug-in, is diagnosed at the bench with a multimeter, an oscilloscope, & a current-limited supply before any firmware work begins. This section extends our ssd data recovery workflow with the exact resistance thresholds, the PCIe CEM power-up handshake the scope should capture, the tantalum-polymer failure mode that hides behind a passing short test, & the controlled power-cycle protocol used to image controllers that hang mid-read.

Resistance-to-Ground Triage Table

The first measurement on a dead drive is resistance from each rail's decoupling capacitor to ground, with the host disconnected. Healthy boards present rail-dependent baselines that look low to anyone used to HDD PCBs. The 0.85V to 1.0V core rail supports high-density CMOS logic; a dormant rail-to-ground reading near 10 to 50 ohms is a normal baseline for the parallel quiescent leakage paths, ESD diodes, & parasitic junction capacitances inside the controller, not a short.

Diode-mode confirms what resistance suggests. A healthy 3.3V rail reads 0.300V to 0.500V forward drop. A core rail reads 11 to 37 mV; that is the silicon's intrinsic drop, not a fault. A true short reads 0.000V on both sides of the same decoupling capacitor.

M.2 NVMe Power-Up Handshake on the Oscilloscope

Once the rails pass resistance triage, the next question is whether the controller boots when power is applied. The PCIe CEM specification fixes the timing the host & the SSD must satisfy. Probing five signals captures the entire handshake & localizes the fault to power delivery, host clocking, or controller firmware.

1. 3.3V_AUX & 3.3V main rail ramp. The host's M.2 supply must ramp monotonically & stabilize. A sagging or oscillating 3.3V on plug-in points to a downstream short the PMIC is reflecting back to the regulator. Stop here if the rail will not hold.
2. PMIC PWR_EN assert. Once the 3.3V input is stable, the PMIC's internal sequencer (or a dedicated enable from the controller's housekeeping domain) drives its PWR_EN logic high & sequences 1.8V, 1.2V, & the core rail. Missing PWR_EN, with 3.3V present, points to the PMIC IC itself.
3. 100 MHz REFCLK presence. The host's differential reference clock must be stable for at least 100 µs before PERST# is released (PCIe parameter T_PERST#-CLK). No REFCLK means the upstream root complex is not ready, not the SSD.
4. PERST# de-assertion on M.2 pin 50. PERST# is an active-low fundamental reset driven by the host. PCIe T_PVPERL requires the host to hold PERST# asserted for a minimum of 100 ms after power & clocks are valid. When PERST# goes high, the controller's power-on reset releases & the boot ROM runs.
5. Link training start. After PERST# de-asserts, the controller has 20 ms to begin LTSSM link training. If link training never starts, the controller boot ROM hung; if it starts & then collapses, the firmware loaded but panicked. The NVMe layer above will never set CSTS.RDY=1, & the device disappears from BIOS enumeration.

The widely-repeated "NVMe drives have 100 ms to boot" rule is a misreading of the spec. T_PVPERL is the host-side hold time on PERST#, not an endpoint boot budget. The endpoint's actual window is the 20 ms link-training start after reset is released.

Tantalum Polymer Failure: The Short Test That Passes

Enterprise & high-end consumer SSDs carry tantalum polymer bulk capacitors on the Power Loss Protection circuit. Their failure mode is different from the MLCC ceramics elsewhere on the board, & that difference defeats a naive short hunt.

Why tantalum polymer caps do not always short

Traditional MnO2 tantalums short violently under overvoltage; the manganese dioxide cathode supplies oxygen & the part can ignite. Tantalum polymer caps replace MnO2 with a conductive polymer cathode (ESR around 6 to 150 mΩ). When a dielectric defect punches through, Joule heating breaks the polymer chain locally & transforms the conductive polymer into a non-conductive barrier. That self-healing isolates the short. The part typically fails open or high-resistance rather than dead-short.

Diagnostic signature

Resistance & diode-mode short tests pass. The drive still fails its internal Power-Loss Protection BIST on boot, the controller refuses to leave its housekeeping state, & the bus drops within a few seconds of enumeration. Capacitance & ESR meters reveal the missing bulk capacitance; visual inspection rarely shows damage because the polymer self-heals internally.

Contrast with surge-failed MLCCs

Cracked MLCCs from PCB flex or surge events bridge their internal electrode layers & read as a dead short across the bypass node. The fault is loud on a multimeter. The tantalum polymer fault is silent on a multimeter & loud only on a capacitance bridge or a controller PLP self-test log.

Lifting a Shorted Tantalum with the Hakko FM-2032

When a tantalum does short (the self-healing capacity was overwhelmed), the part is lifted before any further injection testing. Leaving a shorted bulk cap on the rail guarantees the donor PMIC or replacement regulator dies the moment power is applied.

1. Pre-heat the PCB underside to roughly 150°C on a hot plate. This narrows the temperature gradient across the lifted joint & protects nearby MLCCs from cracking on cool-down.
2. Tin one Hakko FM-2032 tip with fresh leaded solder, then bridge the cap's anode & cathode terminations. Apply a second tip from the opposite side so both terminations reflow within a couple of seconds & the part lifts cleanly without pulling pads.
3. Wick the pads, inspect for any remaining tombstoned solder under the microscope, & re-measure rail-to-ground resistance & diode drop. A short that lifts with the cap confirms the part was the fault. A short that persists means the next upstream or downstream component on the rail is also damaged.
4. Replace with a tantalum polymer of the same case size, rated voltage, & ESR class. Reflow on Atten 862 hot air with shield foil over adjacent NAND packages. Repeat the diode-mode reading; the healthy rail returns to the values listed in the triage table.

Controlled Power-Cycle Imaging for Intermittent Boot

Some controllers enumerate, deliver a few thousand sectors, & then hang on a degraded NAND read. The Low-Density Parity-Check engine exhausts its read-retry budget; on SATA SSDs the firmware hangs with the ATA BSY bit asserted, while NVMe controllers either fail to assert CSTS.RDY or raise Controller Fatal Status (CSTS.CFS). Either way the host sees the bus disappear. Conventional OS drivers respond by issuing a bus reset that the panicked controller ignores, or by dropping the link entirely. Imaging continues only when power, not software, drives the recovery loop.

PC-3000 SSD's power-glitch & controlled power-cycle feature drives the rail relay on the recovery adapter, not the host OS. The sequence on a hung controller is deterministic.

1. The imaging session times out a sector range that has stalled (millisecond-level threshold, not the multi-second OS default).
2. PC-3000 cuts 3.3V on the adapter, waits for residual rail voltage to drain below the controller's power-on-reset threshold (a few hundred milliseconds, depending on bulk capacitance), then re-applies power.
3. The controller cold-boots. PC-3000 re-injects its microcode loader into controller SRAM via the vendor technological mode, restoring the virtual translator without relying on the panicked native firmware.
4. The imaging job resumes from the last known good LBA, skipping the stalled range & marking it for later read-retry at shifted NAND read voltage thresholds. Strict per-sector timeouts prevent the controller from re-entering the same LDPC cascade on retry.

This is what "power cycling" means at the lab bench, & it is not the consumer-forum advice to leave a drive in the BIOS for 30 minutes. That idle trick only allows a healthy controller to run garbage collection. It does nothing for a firmware panic, a BSY lockup, or an LDPC read-retry collapse, because the controller is halted the entire time.

A board that survives rail repair, passes the PCIe handshake on the scope, & completes a power-cycled image lands in the $450–$600 (SATA) or $600–$900 (NVMe) circuit board repair tier. Rush service: +$100 rush fee to move to the front of the queue. Diagnosis is free; no recovered data means no recovery fee.

FTL reconstruction is the process of rebuilding a corrupted Flash Translation Layer using the PC-3000 SSD's controller-specific utilities. The procedure bypasses the panicked controller firmware, injects a working microcode loader into SRAM, and algorithmically rebuilds the logical-to-physical address map from surviving NAND metadata. On encrypted drives, the hardware AES decryption pipeline stays active throughout.

Five-Phase Recovery Workflow

1. 1.

   Technological Mode Entry

   PC-3000 manipulates the SATA or PCIe interface to halt the corrupted firmware boot cycle. Depending on the controller family, this involves bridging specific PCB test points (ROM pin shorting on Phison), issuing proprietary Vendor Specific Commands (Samsung SATA controllers), or forcing past a stalled initialization via vendor ATA commands (Silicon Motion BSY state). The controller stops trying to boot from its corrupted service area.

2. 2.

   SRAM Microcode Injection

   A working microcode loader is pushed into the controller's volatile SRAM. This temporarily boots the controller into a known-good diagnostic state, providing raw NAND access without touching the corrupted firmware in the service area. On drives with hardware AES-256 encryption, the injected loader preserves the decryption pipeline so extracted data is plaintext, not ciphertext.

3. 3.

   NAND Page Header Scan

   The PC-3000 utility scans physical NAND pages across all dies, reading service area metadata, page headers, wear-level counters, and block sequence numbers from surviving blocks. This raw scan can take 2 to 12 hours depending on NAND capacity and cell degradation level. Blocks with uncorrectable ECC errors are flagged for read-retry in Phase 5.

4. 4.

   Virtual Translator Construction

   The PC-3000 software uses the extracted metadata to emulate the controller's FTL logic in the recovery workstation's RAM. Block sequence numbers and page timestamps establish the correct write order. Wear-level counters resolve conflicts where multiple physical pages claim the same logical address. The result is a rebuilt logical-to-physical address map that the recovery workstation presents as a virtual drive with the original capacity and file system structure.

5. 5.

   Data Extraction with Read-Retry

   With the virtual translator active, the drive presents its real capacity. PC-3000 images sector-by-sector to a target drive, applying hardware read-retry sequences and adjusted read voltage thresholds for cells degraded by partial page programming or wear. TLC and QLC NAND cells with ambiguous voltage states get multiple read passes at shifted threshold levels to maximize data yield.

SATA SSD firmware recovery after power loss costs $600–$900. NVMe firmware recovery costs $900–$1,200. If the board also needs PMIC repair before FTL work can begin, the circuit board tier applies first: $450–$600 (SATA) or $600–$900 (NVMe). Rush service: +$100 rush fee to move to the front of the queue.

Controller-Specific FTL Workflow Differences

Each controller family stores FTL metadata in different structures and enters different panic states after power loss. The PC-3000 loads a controller-specific module for each.

Phison (PS3111-S11 SATA, PS5012-E12 NVMe)

SATA variants enter ROM MODE via the SATAFIRM S11 panic state; NVMe variants (E12) drop off the PCIe bus or report a generic ROM state. The Phison-specific loader accesses panic registers and reads the service block area where FTL snapshots are stored. The virtual translator is rebuilt from surviving page metadata in these service blocks. Phison's FTL uses a log-structured merge approach; recovery depends on how much of the merge log survived the power event.

Silicon Motion (SM2258, SM2259XT, SM2262EN)

BSY state or generic 1GB ROM mode. PC-3000 forces the controller past stalled initialization using vendor ATA commands unique to the SM22xx family. FTL reconstruction reads dedicated system blocks where Silicon Motion controllers store mapping table checkpoints. The SM2259XT (used in DRAM-less budget SATA SSDs like the Crucial BX500) is prone to power-loss FTL corruption because it relies on a small internal SRAM cache instead of dedicated DRAM for FTL metadata.

Samsung SATA (MKX) and Samsung NVMe (Elpis, Pascal)

Samsung SATA (MKX) and NVMe (Elpis, Pascal) controllers have limited PC-3000 support; firmware-level FTL reconstruction is not currently available for these chips. Hardware AES-256 encryption binds the media encryption key to the controller die. If the controller is electrically dead, board repair to restore the power delivery circuit is the only viable recovery path so the original controller can boot and decrypt the NAND.

Marvell (88SS1074)

PC-3000 SSD supports the Marvell 88SS1074, so firmware-level FTL reconstruction is available for this controller; the controller's LDPC error correction is why recovery runs through the original controller rather than raw NAND reads. Board-level repair to restore power delivery comes first when the failure is strictly electrical, after which the controller can boot. The 88SS1074 is found in drives like the WD Blue 3D SATA and SanDisk Ultra 3D.

Journal Replay vs. Full NAND Scan

PC-3000 uses two methods to reconstruct the FTL after power loss. The choice depends on whether the controller's journal entries survived the outage.

Journal Replay (primary method)

PC-3000 targets the SSD's reserved service area, scanning for surviving FTL journal logs. These logs record recent delta changes to the mapping table. The utility replays these transactions sequentially in the recovery workstation's RAM, rolling back corrupted state to assemble a virtual translator. Journal replay is faster & produces higher data yield when journal entries survive intact.

Full NAND Scan (fallback method)

If the journal itself is destroyed, PC-3000 falls back to reading raw page-level metadata across all physical pages: spare area bytes, page headers, & logical block sequence numbers. The map is reconstructed from scratch. This process takes 2 to 12 hours per TB depending on NAND condition & cell degradation, but it is resilient against severe journal corruption where replay isn't possible.
