If your Thecus has failed due to a hard drive crash, the RAID no longer works, a RAID rebuild has left the device unable to boot, or it’s just hanging, our engineers will be able to advise you what to do next.
If you updated the firmware and you cannot access the device, it may have resulted in a corrupt volume, or even a corrupt system. At this point, you should stop further recovery attempts; you could make the situation worse and could even cause permanent damage to the data. It’s important that all the disks are backed up before further recovery attempts are made.
Our engineers also recover deleted data; if this is what has happened in your case, it is often necessary to immediately remove power to the device. Please call us so that we can explain why this might be the case.
Because they have experience of all operating systems (Windows, Apple OS, Linux, UNIX, Solaris, Novell) and all file systems (NTFS, Apple HFS+, XFS, ZFS and others) they are in a position to recover your drive, restore data, and get you back in business again. Quickly. And with no fuss.
Their experience of RAID recovery and RAID storage is industry-leading. As such, they are able to work on any RAID level supported by the Thecus range. If you want your data back urgently, with our guarantee of no further data loss or damage, please contact us.
Our engineers consistently recover data from storage systems that other companies have considered non-recoverable. If you are in this situation, we recommend you allow us the opportunity to diagnose the RAID. Too often, we have seen data condemned; in the worst case, this has resulted in the collapse of the company. We did manage to recover the data in every situation. But too late.
Give us a call. We never charge for diagnosis, and our RAID recovery success rate is 100%. Not one failure since June 2009.

Failed Thecus NAS causes:
- Failed hard drive – red LED glows
- Firmware upgrade failed or firmware corruption
- RAID expansion failed
- RAID migration failed
- Corrupt file system or RAID
- Cannot access the device or share
- Thecus RAID rebuild failed
- Volume corruption
Emergency Thecus data recovery. If your Thecus NAS has multiple drives configured with RAID, we can (usually) regenerate the RAID parameters, rebuild the RAID array and start recovering and extracting your data from within as little as one hour of making secure copies of the drives.
