Enterprise RAID & NAS
Several failed disks, an array that won’t mount, a dead Synology or QNAP NAS: RAID rebuilds demand method and equipment — no improvisation.
A failed RAID isn’t "rebuilt" blindly
A RAID protects against one disk failing, not against everything. When a second disk drops, a rebuild fails or a controller corrupts the configuration, the array no longer mounts. The worst mistake is to force a rebuild or restart the NAS: it can permanently overwrite the remaining data.
Recovering a RAID means reconstructing the exact array parameters — disk order, stripe size, parity rotation, offset — from the disks themselves, then reassembling the volume offline. It is analytical work, not a click.
Our method, step by step
Image every disk
We image each member individually, read-only, never writing to the original disks or attempting a rebuild.
Parameter reconstruction
We analyse to recover the order, stripe size, parity type (RAID 5/6/10) and offset, then virtually assemble the array.
File-system mounting
We rebuild the volume (NTFS, ext4, Btrfs, ZFS…), including Synology SHR and QNAP configurations, and virtual machines where applicable.
Extraction & verification
We extract the data to a secure medium, with integrity checks and the folder tree returned as-is.
Our equipment
AceLab PC-3000
PC-3000 UDMA, Flash and Portable PRO — direct disk access bypassing the OS, service-area and firmware access.
ISO 5 cleanroom
Opening drives and swapping heads dust-free (Class ISO 5), without contaminating the platters.
Micro-soldering
Micro-soldering stations to restore damaged controller boards, ROM chips and logic circuits.
Why trust us with a critical RAID
An enterprise RAID is often business-critical: every hour of downtime costs. We work read-only on images — never on your original disks — to guarantee no attempt makes things worse, and we offer an emergency service.
Everything is handled in-house in Brussels, without shipping your business disks abroad — a real plus for confidentiality. It is the same engineer since 2012 who runs the case, directly. Free diagnosis, No Cure, No Pay.
Frequently asked questions
Two disks in my RAID 5 failed — is everything lost?
Not necessarily. Even with two failing disks, it is often possible to image the recoverable members and rebuild the array. Do not attempt a rebuild: bring us all the disks.
Do you recover Synology and QNAP NAS?
Yes, including SHR, Btrfs and ZFS volumes. We rebuild the configuration offline from the disks, without relying on the NAS itself.
Should I shut down the server?
Yes. As soon as a RAID degrades, power it off and do not start a rebuild. Every automatic attempt can overwrite data that is still recoverable.
RAID or NAS down? Don’t force a rebuild — call us.
