Enterprise Synology NAS Data Recovery
Your DiskStation, RackStation, or FlashStation shows Volume Crashed or Storage Pool Degraded. Your shared folders, iSCSI LUNs, and virtual machine datastores are offline.
We recover enterprise Synology arrays through member-by-member imaging and offline SHR/SHR-2 reconstruction. Every drive is cloned through a write-blocker before any analysis begins.
All work happens at our Austin, TX lab. Free evaluation, no data = no charge.
How is data recovered from a failed enterprise Synology NAS?
Every member drive is imaged write-blocked with PC-3000 or DeepSpar, the SHR or SHR-2 geometry is read from the mdadm superblocks offline, the LVM logical volume is rebuilt from those images, and the Btrfs or EXT4 filesystem is extracted at our Austin lab. No data means no fee.
We recover data from Synology's full enterprise lineup: desktop DiskStation Plus units, rackmount RackStation appliances, and all-flash FlashStation systems. The recovery approach is the same regardless of form factor.

SHR-2 Architecture03/12
What Makes SHR-2 Recovery More Complex?
SHR-2 (Synology Hybrid RAID with dual parity) provides RAID 6 equivalent protection and tolerates two simultaneous drive failures. When drives have mixed capacities, SHR-2 creates multiple mdadm arrays at different capacity boundaries and combines them with LVM to form a single logical volume. Recovery gets complicated when the failure involves more than just the drives themselves.
How SHR-2 Stores Data
DSM partitions each drive into system areas (md0, md1 for DSM OS and swap) and data areas (md2+ for user volumes). SHR-2 creates mdadm RAID 6 arrays across the data partitions.
When drives have mixed capacities, SHR-2 creates multiple mdadm arrays at different capacity boundaries and combines them with LVM to form a single logical volume.
Btrfs or EXT4 sits on top of the LVM logical volume. Btrfs adds its own metadata layer: chunk trees, device trees, and subvolume trees that map logical block addresses to physical locations on the virtual array.
What Makes Enterprise Recovery Harder
Larger arrays (8-24 bays) require imaging and reconstructing more members, which increases the probability that at least one drive has bad sectors requiring retry-intensive imaging.
High-capacity drives (16TB+) in RackStation units may be helium-sealed. These drives cannot be opened like standard air-breather HDDs. Head swaps require matched donor drives and a controlled environment on our 0.02 micron ULPA laminar flow bench.
Expansion units (DX/RX series) add drives across a separate eSATA or SAS connection. If the expansion shelf fails, DSM marks those members as missing, which can crash the volume even though the drives are physically intact.
Do not rebuild a degraded SHR-2 array on aging drives. The sustained I/O load of a parity recalculation stresses every remaining member. SHR-2 carries dual parity, so a second drive failure during the rebuild drops it to single-parity degraded rather than crashing it; the danger is a third concurrent failure, which exceeds its tolerance.
If the replacement drive uses SMR (Shingled Magnetic Recording) technology, the rebuild may stall on band-rewrite latency past the controller timeout, so the controller ejects a third member and pushes the array beyond what dual parity can reconstruct. Power down and contact us.
NVMe SSD Cache Failures04/12
What Happens When an NVMe Cache Drive Fails?
DSM supports NVMe SSD caching in two modes: read-only and read-write. A cache drive failure in read-only mode is inconvenient but not destructive because the cache only holds copies of frequently accessed blocks. In read-write mode, write-back cache holds dirty data that has not yet been flushed to the HDD array, which can cause an immediate Volume Crashed state.
Read-Only Cache Failure
Read cache stores copies of frequently accessed blocks. When the NVMe drive fails, DSM falls back to reading directly from the HDD array.
No data is lost because the cache never held uncommitted writes. Performance degrades, but the volume remains intact.
Read-Write Cache Failure
Write-back cache holds dirty (uncommitted) data that has not yet been flushed to the HDD array. If the NVMe drive fails before flushing, the Btrfs filesystem becomes desynchronized: the on-disk metadata references extents that were never written to the mechanical array. DSM reports Volume Crashed because it cannot reconcile the metadata gap.
How We Handle NVMe Cache Recovery
Image the failed NVMe cache drive separately. NVMe SSDs use monolithic BGA packages with controller-level encryption. If the controller is dead, chip-off extraction is not viable. We perform board-level repair to restore controller functionality, then image the drive using PC-3000 SSD.
Extract dirty cache extents from the NVMe image. DSM stores write-cache metadata in a proprietary format on the NVMe partition. We parse this metadata to identify which blocks were pending flush to the HDD array.
Reconstruct the HDD array and overlay the cache data. The mechanical member images are assembled normally through mdadm reconstruction. The recovered cache extents are then applied to fill the metadata gaps in the Btrfs volume.
If the NVMe cache drive is physically unrecoverable (NAND degradation beyond repair, or TRIM has cleared the blocks), the uncommitted writes stored on that drive are permanently lost. The rest of the array data, everything that was already flushed to the HDDs, is still recoverable through normal SHR reconstruction.
Process05/12
How We Recover Enterprise Synology Arrays
We follow the same image-first, offline reconstruction workflow for every enterprise Synology, regardless of model or bay count. Each member drive is connected through a hardware write-blocker and imaged with PC-3000 or DeepSpar. We read mdadm superblocks from each imaged copy to determine stripe size, parity rotation, and member order; your original drives are never modified.
Enterprise Synology appliances are one branch of our broader NAS data recovery work, and the same image-first, offline reconstruction discipline applies whether the unit is a four-bay DiskStation or a rackmount RackStation with expansion shelves.
Free evaluation and configuration audit: We document your Synology model, DSM version, SHR/SHR-2 configuration, member drive models, NVMe cache configuration (if applicable), expansion unit connections, and any prior repair or rebuild attempts.
Write-blocked forensic imaging: Each member drive is connected through a hardware write-blocker and imaged with PC-3000 or DeepSpar. Drives with weak heads or bad sectors get conservative retry profiles and head maps. Helium-sealed enterprise drives that need head swaps are opened on our clean bench with matched donor parts.
mdadm and LVM metadata capture: We read mdadm superblocks from each imaged copy to determine stripe size, parity rotation, and member order. For SHR/SHR-2 with mixed-capacity drives, we reconstruct the LVM volume group that ties multiple mdadm arrays together.
Virtual array reconstruction: We assemble the virtual SHR/SHR-2 array from cloned images. Parity is validated across all members before filesystem extraction begins.
Btrfs or EXT4 filesystem extraction: We traverse the Btrfs chunk tree, device tree, and subvolume structures to locate shared folders, snapshots, and iSCSI LUN files. For EXT4 volumes, we perform journal replay and inode table reconstruction. XFS volumes follow a similar approach with allocation group reconstruction.
Verification and delivery: Recovered data is copied to a target drive, verified against your priority file list (shared folders, VM datastores, databases), and shipped back. Working copies are securely purged on request.
Rackstation Failover And Expansion06/12
How Do RackStation Failover and Expansion Shelf Failures Cause Data Loss?
Enterprise RackStation models support redundant power supplies, expansion shelves (DX/RX series), and in some configurations, high-availability clustering. When an expansion unit loses its eSATA or SAS connection, DSM marks those member drives as missing. Data loss occurs when a power surge takes both supplies simultaneously, or when a PSU failure coincides with a degraded array state.
Expansion Shelf Disconnect
When a DX517 or RX1223RP expansion unit loses its eSATA or SAS connection (cable failure, controller failure, or accidental disconnect), DSM marks those member drives as "missing." If enough members drop below the redundancy threshold, the volume crashes.
The drives themselves are usually intact. We remove them from both the head unit and expansion shelf, image each one independently, and reconstruct the full array from images.
Power Supply Failures
Dual-PSU RackStation units (RS2423+, RS3621xs+) failover automatically when one supply dies. Data loss occurs when a power surge takes both supplies simultaneously, or when a PSU failure coincides with a degraded array state. In surge scenarios, the sudden power loss can corrupt Btrfs transaction logs and leave the filesystem in an inconsistent state that DSM cannot auto-repair.
FlashStation All-Flash NAS07/12
How Is Data Recovered from a Synology FlashStation?
Synology FlashStation units use 2.5" SATA or SAS SSDs as primary storage members, not just cache. Every member drive is a solid-state device. The recovery approach differs from HDD-based arrays.
No head swaps or clean-bench work. SSDs have no moving parts. Failures are electronic (controller death, NAND wear-out, firmware corruption) rather than mechanical.
Controller-level encryption on enterprise SSDs. Many enterprise SATA and SAS SSDs encrypt data at the controller level. The NAND flash is physically soldered as monolithic BGA packages. Chip-off extraction (desoldering and reading NAND chips directly) does not work when the data is encrypted with a key bound to the original controller.
Board-level repair is mandatory for dead SSDs. If the SSD controller fails, we perform component-level board repair (replacing failed voltage regulators, controller chips, or crystal oscillators) to restore the drive to a state where PC-3000 SSD can communicate with the controller and extract the data through firmware commands.
TRIM complicates recovery. If TRIM has executed on deleted blocks, those blocks are physically zeroed by the SSD controller. Data from TRIM'd regions cannot be recovered regardless of the tools used. This is a physical limitation of NAND flash architecture, not a software problem.
Pricing08/12
How Much Does Enterprise Synology NAS Recovery Cost?
Enterprise NAS recovery uses two-tiered pricing: a per-member imaging fee based on each drive's condition, plus a separate array reconstruction line item. Air-filled HDD members use From $250 to $600–$900 for logical and firmware issues, and $1,200–$1,500 for mechanical head swaps. Helium-sealed enterprise drives use helium HDD pricing from $200–$5,000+; if we recover nothing, you owe $0.
Logical/Firmware per Drive
$250 to $900
For HDD members with firmware corruption, file system damage, or SMART threshold failures. Most enterprise NAS members with logical issues fall in this range. PC-3000 terminal access for firmware repair.
Mechanical HDD per Drive
$1,200 to $1,500
Air-filled HDD members with clicking, beeping, or failed heads use this tier. 50% deposit required; donor parts are consumed during the transplant. Helium-sealed enterprise drives (16TB+) use $3,000–$4,500 head swap or $4,000–$5,000 surface damage pricing, plus helium and donor costs.
Array Reconstruction
Single line item
Covers SHR/SHR-2 parameter detection, LVM reconstruction, virtual assembly, Btrfs/EXT4 extraction. Cost depends on member count, RAID level, and filesystem complexity.
FlashStation SSD members that require board-level repair to restore controller accessibility use $600–$900 SSD firmware recovery pricing. Functional SSDs that only need logical imaging use From $250 pricing.
Per-member HDD imaging follows our published hard drive tiers, from a $100 simple copy up through firmware & mechanical work. The same rates apply whether the drive came out of a four-bay DiskStation or a 12-bay RackStation.

Hardware Repair vs. Software Locks
Our "no data, no fee" policy applies to hardware recovery. We do not bill for unsuccessful physical repairs. If we replace a hard drive read/write head assembly or repair a liquid-damaged logic board to a bootable state, the hardware repair is complete and standard rates apply. If data remains inaccessible due to user-configured software locks, a forgotten passcode, or a remote wipe command, the physical repair is still billable. We cannot bypass user encryption or activation locks.
No data, no fee. Free evaluation and firm quote before any paid work. Full guarantee details. Head swap and surface damage require a 50% deposit because donor parts are consumed in the attempt.
Rush fee
+$100 rush fee to move to the front of the queue
Donor drives
Donor drives are matching drives used for parts. Typical donor cost: $50–$150 for common drives, $200–$400 for rare or high-capacity models. We source the cheapest compatible donor available.
Target drive
The destination drive we copy recovered data onto. You can supply your own or we provide one at cost plus a small markup. For larger capacities (8TB, 10TB, 16TB and above), target drives cost $400+ extra. All prices are plus applicable tax.
No Data = No Charge. If we cannot recover usable data from your enterprise Synology, you owe nothing. Optional return shipping is the only potential cost on an unsuccessful case.

Btrfs Metadata Recovery10/12
What Does Btrfs Metadata Recovery Involve?
DSM 7.x defaults to Btrfs on all supported enterprise models. Btrfs uses a copy-on-write B-tree architecture with separate metadata structures for chunk allocation, device mapping, and subvolume organization. When the volume crashes, one or more of these trees may be corrupt.
Chunk Tree Corruption
The chunk tree maps logical addresses to physical locations across array members. When this tree is damaged, Btrfs cannot locate data blocks even though they exist on disk. We reconstruct the chunk tree from the device tree and stripe information embedded in the mdadm layer below.
Subvolume and Snapshot Trees
Each shared folder in DSM is a Btrfs subvolume with its own root tree. Snapshots create additional tree references. If the main subvolume tree is damaged, we traverse snapshot trees as an alternate path to the same data blocks.
Transaction Log Replay
Btrfs maintains a log tree for crash recovery. If the volume crashed mid-write, pending transactions may be replayable from the log tree. This is particularly useful for recovering recent changes that were not yet committed to the main trees.
DUP Metadata Profile
On single-device volumes, Btrfs stores two copies of metadata blocks (DUP profile). On multi-device arrays, metadata is distributed via RAID profiles. If one copy of the metadata is damaged, the redundant copy may still be traversable.
CoW-Safe Forensic Tools
Because Btrfs is copy-on-write, it never overwrites a metadata block in place. It writes a new version elsewhere and updates a pointer, so older B-tree generation roots survive on disk after a crash. We use btrfs-find-root to scan the raw block device for those surviving historical generation roots, then btrfs restore to extract file data from a nominated generation root without writing a single byte back to the device.
We avoid btrfsck --repair and mount -o recovery,ro on the originals. Both write to disk, and both overwrite the older generation tree roots that survive precisely because of copy-on-write. Professional Btrfs recovery skips in-place repair and works read-only from imaged members, never the customer drives.
DSM 7.2 LUKS Volume Encryption11/12
How Does DSM 7.2 Volume Encryption Affect Recovery?
DSM 7.2 introduced full-volume encryption using LUKS in aes-xts-plain64 mode. The volume's auto-mount wrapped key is managed by a local or remote KMIP Encryption Key Vault. If the vault is lost or corrupted, or the wrapped key is destroyed, and no recovery key was saved, decrypting the volume is mathematically impossible.
LUKS aes-xts-plain64 Volume Encryption
DSM 7.2 encrypts the entire volume with LUKS in aes-xts-plain64 mode. Encryption sits below the Btrfs or EXT4 filesystem on the LVM logical volume, so the array can be imaged member by member like any other Synology. The catch is that the imaged blocks are ciphertext until the volume is unlocked. Reconstructing the SHR geometry from the images gives you the encrypted container, not the files inside it.
Encryption Key Vault and the Wrapped Key
Key management is handled by a local Encryption Key Vault or a remote KMIP server. The volume auto-mounts using a wrapped key tied to the vault, and the vault is what releases the master key at boot. That wrapped key is bound to the original vault. It is not a copy you can carry to another unit, so moving the imaged drives to a donor Synology fails without the saved recovery key.
When Recovery Is Mathematically Impossible
If the Key Vault is lost or corrupted, or the wrapped auto-mount key is destroyed, and the user never exported and saved the recovery key or passphrase, there is no key to unwrap. Brute-forcing aes-xts-plain64 without the key is computationally infeasible, so extraction is mathematically impossible. This is the one failure mode no laboratory can defeat. Imaging recovers ciphertext, not plaintext.
What To Save Before A Failure
The exported recovery key or passphrase is the only thing that makes a future decrypt possible. Export it when you enable encryption and store it off the NAS. Without it, a healthy array of imaged drives still yields only ciphertext, and no amount of array reconstruction changes that.
Synology Drive Compatibility12/13
Is Data Recoverable from an Unverified or Non-Compatible Synology Drive?
Yes. Synology Drive Compatibility (SDC) certification and the IHM unverified-drive flag are DSM management signals, not storage-layer facts. The array geometry lives in the mdadm superblocks on each member, so an unverified drive pulled from a crashed array recovers through the same write-blocked imaging and offline reconstruction as a certified drive.
Where the Array Geometry Actually Lives
Each member carries an mdadm superblock (metadata version 1.2) that records stripe size, parity rotation, member order, and the event counter. That metadata is independent of DSM's drive-certification database; the certification status of a drive has no bearing on the RAID layout written to its data partitions.
SHR and SHR-2 are mdadm plus LVM plus Btrfs or EXT4 on standard Linux. An SHR array reassembles and mounts on a standard Linux workstation without any Synology hardware, which is exactly why an unverified member is no obstacle to offline reconstruction.
What SDC and IHM Actually Gate
DSM marks a drive that is not on the SDC list as unverified and limits IHM predictive-failure monitoring on it. The observable result is an "unverified" or "at risk" status against that member inside DSM.
Those flags affect DSM management posture and Synology's warranty and support stance. They do not change whether the data can be reconstructed offline, because they never touch the on-disk RAID metadata.
Hazards of Bypassing SDC: SMR Members
The genuine reason to avoid uncertified drives is SMR (Shingled Magnetic Recording) consumer drives as array members. Under the sustained sequential writes of a rebuild, an SMR member stalls for 30 to 60 seconds on band-rewrite latency. The Linux md driver reads that stall as a dead drive and ejects the member, which can crash the volume.
This is a physics-based failure, separate from the recoverability point above. A degraded SHR-2 or RAID 6 array should be imaged member by member through a write-blocker before any rebuild is attempted, because unrecoverable read error math on large arrays makes a live rebuild the riskier path.
DriveError Flag and Offline Reassembly
Synology's customized md driver sets a DriveError flag that blocks repairs from the DSM interface once a member has been faulted. The array can still be queried, stopped, and reassembled with standard Linux mdadm offline. The certification layer never writes to the on-disk RAID metadata, so the flag controls DSM behavior, not the recoverability of the data.
iSCSI LUN Sparse-File Extraction13/14
How Is a Synology iSCSI LUN Actually Stored?
An Advanced iSCSI LUN on DSM is not a physical partition or a separate block device. It is a large sparse file named EP_DAT_00000 inside a hidden @iSCSI directory on the underlying Btrfs or EXT4 volume. That volume sits on LVM, which sits on the mdadm SHR or SHR-2 array. To reach your VM datastore, every one of those layers has to be rebuilt in order.
VMware vSphere and Hyper-V deployments back their datastores & Cluster Shared Volumes to iSCSI targets on RackStation and DiskStation units, so when a RS3621xs+ or FS6400 loses its volume, an entire datastore of virtual machines goes offline at once. Most labs generalize this as "SAN recovery" & skip the @iSCSI sparse-file container layer entirely, which is the layer that actually holds your data.
Advanced LUN (File-Based)
An Advanced LUN is the EP_DAT_00000 container file living on the host Btrfs or EXT4 filesystem. It can be thick-provisioned (the full capacity is pre-allocated at creation) or thin-provisioned. When thin-provisioned it operates as a sparse file: it appears to the iSCSI initiator at its full provisioned size, but the host filesystem only allocates extents on demand as data is written, so large stretches of the LUN are never physically written.
Block-Level LUN (Legacy)
A legacy Block-level LUN bypasses the host filesystem & is carved directly from the LVM storage pool as its own logical volume. There is no EP_DAT_00000 container to extract, but the LVM volume group & the mdadm array underneath it still have to be reconstructed before the LUN is readable.
You cannot just pull the LUN as a separate disk or reconnect the target on a new NAS. For an Advanced LUN there is no separate disk to pull. The data is embedded inside the EP_DAT_00000 file, inside the host Btrfs or EXT4 filesystem, on top of LVM, on top of the mdadm RAID slices. Moving the drives into a fresh enclosure & choosing Migrate or Repair can instruct DSM to rewrite the system partitions & forcefully reimport the array, which frequently fails over into a fresh-install prompt that overwrites the data partitions holding that container.
If the host volume is LUKS-encrypted, the container is only reachable after the volume is unlocked with the saved recovery key.
The Three-Stage Extraction
Image every member, then rebuild SHR/SHR-2 offline. Each array member is cloned write-blocked with PC-3000 or DeepSpar, then the SHR or SHR-2 mdadm array & the LVM volume group are reassembled from those images. On a large, degraded SHR-2 array, unrecoverable read error math means a live rebuild is likely to hit a read error mid-parity-recalculation, so we image member by member first & never rebuild on the original drives.
Mount the host filesystem read-only & extract the container. We mount the host Btrfs or EXT4 volume read-only, traverse the subvolume tree to the @iSCSI directory, and extract the EP_DAT_00000 container. For a thin-provisioned LUN we preserve its sparse layout rather than materializing the zero-filled extents, because materializing those zeros would inflate the file to its full provisioned size & destroy the thin-provisioning map the initiator filesystem depends on.
Mount the container as a loop device & recover the VM files. The extracted EP_DAT_00000 container is attached as a loop block device to reach the filesystem the initiator wrote inside it: VMFS for VMware vSphere, or NTFS for Windows and Hyper-V. From there the datastore, VMDKs, or VHDX files are read out & copied to the target drive.
Faq14/14
Enterprise Synology Recovery FAQ
Which enterprise Synology models do you recover?
We recover data from the full range of Synology enterprise appliances: DiskStation Plus series (DS920+, DS1522+, DS1821+), RackStation series (RS1221+, RS2423+, RS3621xs+), and FlashStation all-flash units (FS2500, FS3410, FS6400). The recovery process is the same regardless of chassis form factor.
Can you recover data after an NVMe SSD cache drive fails?
It depends on the cache mode. Read-only cache failures do not affect stored data because the cache only holds copies of frequently accessed blocks. Write-back (read-write) cache failures are more serious: uncommitted writes stored on the NVMe drive may be lost if the drive is unrecoverable. We image the failed NVMe cache drive separately and attempt to extract the dirty cache extents before reconstructing the array.
What is the difference between SHR and SHR-2?
SHR (Synology Hybrid RAID) provides single-disk fault tolerance, equivalent to RAID 5 for same-size drives. SHR-2 adds a second parity disk, equivalent to RAID 6. SHR-2 survives two simultaneous drive failures. Both use Linux mdadm under the hood, with LVM layering for mixed-capacity drive support.
My RackStation has redundant power supplies. Can a PSU failure cause data loss?
A single PSU failure in a dual-PSU RackStation should not cause data loss because the second supply takes over. Data loss occurs when both supplies fail simultaneously (surge), when the failover circuitry itself is damaged, or when a PSU failure coincides with a drive already in degraded state. In all cases, power down and avoid rebuild attempts.
Can you recover a FlashStation with all-SSD drives?
Yes. FlashStation recovery follows the same image-first workflow, but every member is a SATA or SAS SSD rather than a mechanical HDD. Enterprise SSDs may use controller-level encryption and monolithic BGA packages; chip-off extraction is not viable when encryption is active. Recovery requires board-level repair to restore drive accessibility, followed by firmware-level imaging with PC-3000 SSD.
Can you recover a Synology drive flagged as unverified or non-compatible?
Yes. The unverified flag from Synology Drive Compatibility (SDC) and the IHM at-risk status are DSM management signals, not storage-layer facts. The RAID geometry lives in the mdadm superblocks on each member: stripe size, parity rotation, member order, and the event counter. Those superblocks are independent of DSM's drive-certification database, so an unverified member from a crashed array recovers through the same write-blocked imaging and offline mdadm, LVM, and Btrfs or EXT4 reconstruction as a certified drive. The real hazard of bypassing SDC is using consumer SMR drives, which stall 30 to 60 seconds during a rebuild and get ejected by the Linux md driver, crashing the volume.
How much does enterprise Synology NAS recovery cost?
Pricing follows two layers: a per-drive imaging fee based on each member's condition, plus a separate array reconstruction line item. Air-filled HDD members use From $250 to $600–$900 for logical and firmware issues, and $1,200–$1,500 for mechanical head swaps. Helium-sealed RackStation members use helium HDD pricing from $200–$5,000+ for mechanical work. FlashStation SSD members that need board repair use $600–$900 pricing. If we recover nothing, you owe $0.

Our engineers review all lab protocols to maintain technical accuracy and honest service. Since 2008, his focus has been on clear technical communication and accurate diagnostics rather than sales-driven explanations.
We believe in proving standards rather than just stating them. We use TSI P-Trak instrumentation to verify that clean-air benchmarks are met before any drive is opened.
“Had a raid 0 array (windows storage pool) (failed 2tb Seagate, and a working 1tb wd blue) recovered last year, it was much cheaper than the $1500 to $3500 Canadian dollars i was quoted by a Canadian data recovery service. the price while expensive was a comparatively reasonable $900USD (about $1100 CAD at the time). they had very good communication with me about the status of my recovery and were extremely professional. the drive they sent back was Very well packaged. I would 100% have a drive recovered by them again if i ever needed to again.”
“HIGHLIGHT & CONCLUSION
******Overall I'm having a good experience with this store because they have great customer services, best third party replacement parts, justify price for those replacement parts, short estimate waiting time to fix the device, 1 year warranty, and good prediction of pricing and the device life conditions whether it can fix it or not.”
“Didn't *fix* my issue but a great experience. Shipped a drive from an old NAS whose board had failed. Rossmann Repair wanted to go straight for data extraction (~$600-900). Did some research on my own and discovered the file table was Linux based and asked if they could take a look. They said that their decision still stands and would only go straight for data recovery.”
