RAID Data Recovery

We can recover your broken RAIDs with our in-house RAID Data Recovery Services. Although RAID gives protection against certain types of hardware failure, there are still plenty of reasons you might need data recovery from a RAID array. Most commonly we see more than one failed disk in a RAID 5 array, or more than two disks in RAID 6. As RAIDs are often made up of similar or matched disks, they often fail at similar times. This can mean multiple disks failing before the array has finished a rebuild. Also if the filesystem becomes damaged, the data can become inaccessible.

A while back there were some Seagate Barracuda disks that had a very regular firmware failure. They would often fail in bunches, breaking RAID arrays all over the place. More recently the Seagate ST2000DM disks are causing more problems.


We apply the same safe process we use for single hard drives and importantly we only work on clones / copies of the RAID members. This helps avoid the RAID controller or operating system starting an automated rebuild or other destructive task. Using our virtual RAID controllers and disk copies, we prevent causing any further damage to the data.

We often see Dell servers with PERC RAID controllers. We see a lot of NAS / SAN devices from brands like LaCie, drobo, Buffalo, OWC, PROAVIO, QNAP & Synology. We also recover a fair amount of Mac Mini servers, and lots of custom Linux systems running md-raid or LVM (or both!). We can also recover from Mac and Windows software RAIDs.

Although it is useful to get as much info as possible before we start a RAID recovery, we can usually determine the layout of the RAID if you don’t know it. We may need a bit longer, but it shouldn’t affect the outcome. We ask that the disks remain in their original position if possible, or are at least labelled accurately if they must be removed from their enclosure.

RAID Data Recovery Enquiry

For prices & turnaround times give us a call or contact us to request more info. The more info you provide, the better. When enquiring about our RAID Recovery, please include:

  • Hardware info
  • Operating System
  • Capacity of individual drives, data volume & array
  • Turnaround time required. We can sometimes offer a cheaper slower process
  • What happened / failure symptoms
  • Any work carried out so far
  • Anything else that you think may affect the recovery

We regularly carry out RAID data recovery from Windows / Linux Servers, Mac Pros / Apple Software RAIDs, or externally attached RAID arrays and NAS devices.
