Dell PERC H730 Data RecoveryDell PowerEdge R730 / Dell PowerEdge R730xd / Dell PowerEdge R630

Dell PERC H730 data recovery at Rossmann Group in Austin, Texas. This Dell hardware raid controller supports RAID levels 0, 1, 5, 6, 10, 50, 60 across up to 32 drives via SAS/SATA. Commonly found in Dell PowerEdge R730, Dell PowerEdge R730xd, Dell PowerEdge R630. 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 foreign configuration detected. All work is backed by our no-data-no-fee guarantee; you pay nothing if we cannot recover your files.

Dell PERC H730 Specifications

The Dell PERC H730 uses a rebranded LSI SAS3108 ROC with 2GB DDR3 cache. It stores RAID metadata in DDF (Disk Data Format) on reserved sectors at the end of each member drive, plus a copy in controller NVRAM. Default stripe size is 64KB with left-symmetric parity rotation. PC-3000 RAID Edition reads the DDF superblock directly from the drive images to reconstruct the array without needing the original controller.

Recovery Tool Support

PC-3000 RAID Edition: Supported
Manual Reconstruction: Supported

PC-3000 RAID Edition reads the DDF superblock directly from the drive images to reconstruct the array without needing the original controller. Default stripe size is 64KB with left-symmetric parity rotation.

Compatible Server Lines

The Dell PERC H730 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 Dell PERC H730.

Foreign Configuration Detected

Occurs when drives are moved between PERC controllers or the controller is replaced. PERC writes its own DDF metadata; swapping controllers causes the new PERC to flag drives as foreign because the controller serial number in the metadata does not match.

Symptoms you may notice

  • BIOS/UEFI shows 'Foreign Configuration Detected' during POST
  • Server will not boot to OS
  • Amber blinking on drive activity LEDs

Virtual Disk Degraded / Failed

One or more drives dropped from the array. PERC marks the virtual disk as degraded (single drive loss in RAID 5/6) or failed (beyond redundancy). Automatic rebuild attempts fail if the remaining drives have bad sectors that the controller cannot remap.

Symptoms you may notice

  • OMSA or iDRAC alerts showing virtual disk degraded or failed
  • OS reports I/O errors on the logical volume
  • Server performance drops as PERC retries reads on failing sectors

How We Recover Dell PERC H730 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 Dell PERC H730 controller.

Step 2: Array Reconstruction

We use PC-3000 RAID Edition to reverse-engineer the Dell PERC H730'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 Dell PERC H730 includes a battery-backed or flash-backed write cache (2GB DDR3). 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 Dell PERC H730 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.

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.

Frequently Asked Questions

My PERC H730 shows 'Foreign Configuration Detected' after a controller swap. Can you recover the data?
Yes. The PERC H730 stores DDF metadata on reserved sectors at the end of each member drive. When a controller is replaced, the new PERC flags the drives as foreign because its serial number does not match the metadata. We image the drives and read the DDF superblock directly using PC-3000 RAID Edition to reconstruct the array without needing the original controller.
What stripe size does the PERC H730 use by default?
The H730 defaults to 64KB stripe size with left-symmetric parity rotation. It is configurable from 64KB to 1MB through the PERC BIOS or OMSA. During recovery, PC-3000 RAID Edition reads the stripe size from the DDF metadata, so we do not need to guess the configuration.
Can you recover a PERC H730 RAID 5 array where rebuild failed partway through?
Yes. A failed rebuild leaves the array in a partially consistent state: some stripes have been rebuilt with new parity, others still reference the failed drive. We image all member drives including the replacement, read the rebuild checkpoint from DDF metadata, and reconstruct both the pre-rebuild and post-rebuild stripe regions to produce a complete image.
How much does PERC H730 RAID recovery cost?
Each drive is imaged individually; pricing depends on the drive condition (firmware repair, head swap, etc.). Array reconstruction with DDF metadata parsing is $400-$800 per array. No data recovered means no charge.
