HP Smart Array P408i-a Data RecoveryHPE ProLiant DL360 Gen10 / HPE ProLiant DL380 Gen10 / HPE ProLiant DL560 Gen10
HP Smart Array P408i-a data recovery at Rossmann Group in Austin, Texas. This HP hardware raid controller supports RAID levels 0, 1, 5, 6, 10, 50, 60 across up to 30 drives via SAS/SATA. Commonly found in HPE ProLiant DL360 Gen10, HPE ProLiant DL380 Gen10, HPE ProLiant DL560 Gen10. Per-drive imaging costs $600 to $1,500 depending on drive condition, plus a $400 to $800 array reconstruction fee. The most common failure we handle is array accelerator / cache status: temporarily disabled. All work is backed by our no-data-no-fee guarantee; you pay nothing if we cannot recover your files.
HP Smart Array P408i-a Specifications
HPE Smart Array P408i-a is an embedded controller in ProLiant Gen10 servers. Unlike Dell PERC (which uses DDF), HP Smart Array stores RAID metadata in a proprietary format on a hidden partition (GPT Partition 9) on each member drive. Default stripe size is 256KB. PC-3000 RAID Edition includes an HP Smart Array module that parses the metadata from this hidden partition to determine drive order, stripe size, and parity rotation.

Recovery Tool Support
HP Smart Array uses a proprietary metadata format (not DDF) stored on a hidden GPT Partition 9 on each member drive. PC-3000 RAID Edition includes an HP Smart Array module that parses this metadata to determine drive order, stripe size, and parity rotation. Default stripe size is 256KB.
Compatible Server Lines
The HP Smart Array P408i-a is found in the following server platforms. If your server uses this controller and the array has failed, we can reconstruct the RAID offline from individual drive images.
Failure Modes
RAID controller failures differ from individual drive failures. The controller metadata, stripe maps, and parity calculations must all be intact for the array to function. Below are the failure modes specific to the HP Smart Array P408i-a.
Array Accelerator / Cache Status: Temporarily Disabled
Flash-backed write cache (FBWC) battery or capacitor reports failed during its self-test. Controller disables write cache and forces write-through mode. The array still functions but at degraded write performance. If an administrator does not notice and a drive fails while running in write-through, rebuild times are longer because every write goes directly to disk.
Symptoms you may notice
- HPE Smart Storage Administrator shows 'Cache Status: Temporarily Disabled'
- iLO alerts for cache module failure
- Write performance drops noticeably; sequential write throughput may halve

Logical Drive Failed (1785 POST Error)
Two or more drives in a RAID 5 array fail simultaneously, or both members of a RAID 1 mirror fail. HP metadata marks the logical drive as failed and the array goes offline. The controller reports error 1785 at POST and the OS cannot access the volume.
Symptoms you may notice
- Server shows '1785 - Logical Drive Not Configured' at POST
- OS cannot access the logical volume; filesystem shows as unmounted
- iLO sends critical alert for logical drive failure

How We Recover HP Smart Array P408i-a Arrays
Step 1: Individual Drive Imaging
Every drive from the array is imaged independently using the PC-3000 and DeepSpar Disk Imager. Drives with head failures or firmware corruption are repaired first. Each drive is imaged sector-by-sector to a clean target before any reconstruction begins.
For SAS/SATA drives, we use the appropriate interface hardware. SAS drives require dedicated SAS HBAs; SATA drives connect directly. This preserves every readable sector without relying on the original HP Smart Array P408i-a controller.
Step 2: Array Reconstruction
We use PC-3000 RAID Edition to reverse-engineer the HP Smart Array P408i-a's metadata structure: stripe size, drive order, parity rotation, and offset values. The array is reconstructed from the drive images without needing the original controller hardware.
Once the virtual array is assembled, we extract the file system (NTFS, ext4, XFS, VMFS, ZFS, or other) and verify file integrity before delivering the recovered data.
Battery-Backed Cache
The HP Smart Array P408i-a includes a battery-backed or flash-backed write cache (2GB DDR4). If the server lost power during a write operation, pending writes are preserved in the cache. On restart with a healthy controller, the firmware automatically flushes this cached data to disk; no manual intervention is needed. If the controller itself has failed, recovering cached data requires an identical replacement controller (same model, firmware revision) to which the cache module can be transferred.
Pricing
Recovery pricing for HP Smart Array P408i-a arrays has two components: per-drive imaging and array reconstruction. Drive imaging costs $600–$900 to $1,500 per drive depending on condition (firmware repair vs. head swap). Array reconstruction adds $400 to $800 depending on the number of drives and RAID level complexity.

Data Recovery Standards & Verification
Our Austin lab operates on a transparency-first model. We use industry-standard recovery tools, including PC-3000 and DeepSpar, combined with strict environmental controls to make sure your hard drive is handled safely and properly. This approach allows us to serve clients nationwide with consistent technical standards.
Open-drive work is performed in a ULPA-filtered laminar-flow bench, validated to 0.02 µm particle count, verified using TSI P-Trak instrumentation.
Transparent History
Serving clients nationwide via mail-in service since 2008. Our lead engineer holds PC-3000 and HEX Akademia certifications for hard drive firmware repair and mechanical recovery.
Media Coverage
Our repair work has been covered by The Wall Street Journal and Business Insider, with CBC News reporting on our pricing transparency. Louis Rossmann has testified in Right to Repair hearings in multiple states and founded the Repair Preservation Group.
Aligned Incentives
Our "No Data, No Charge" policy means we assume the risk of the recovery attempt, not the client.
Technical Oversight
Louis Rossmann
Louis Rossmann's well trained staff review our lab protocols to ensure 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.
