Retrodata RAID Recovery

Thecus NAS recovery specialists

If your Thecus has crashed due to a failed hard drive, and it is making a clicking sound, you should power it off. If a failing drive caused a RAID failure and you swapped out the failed drive to perform a RAID rebuild – if that did not work, or if it seems to be hanging or making no progress, please contact us.

Even if you tried a firmware update that failed, or the RAID is running in degraded mode; if you have volume corruption, file system corruption, or either a RAID expansion or RAID migration failed, you need expert assistance. Further, repeated attempts at data recovery will probably cause more damage, and could even lead to total data loss.

Our engineers are standing by. They are experts at recovery, and have in-depth of all operating systems (Apple Windows, Linux, UNIX) and file systems (NTFS, Apple HFS+, Ext3, Ext4, XFS and ZFS). Their RAID recovery skills are industry-leading. They will restore your Thecus and recover your data. Quickly, efficiently, and will no disruption to you.

Why Retrodata? • Can you recover my data? • Emergency Recovery • Why RAID fails

Thecus NAS recovery from all models. Single hard drives and enterprise devices that support Ext3, ZFS and XFS file systems. We work with all RAID levels (RAID 0, RAID 1, RAID 5, RAID 6, RAID 10, JBOD), and all file systems, including Windows NTFS and Mac HFS+. We have the facilities, tools and expertise to restore your inaccessible data and get you back up and running. Within a matter of hours.



Emergency Thecus Recovery. RAID failure? We can normally start the recovery process within one hour of creating backup copies of all your disks.

When we take delivery of your drive, we’ll make secure backup copies of all the disks. This is an insurance policy against further data loss, and against the chance of another drive failing during the recovery process. We’ll keep you updated from the minute we receive the device, until the recovery has completed. Even during the recovery, it’s normally possible to start returning your most important data first, reducing your downtime to an absolute minimum. We’ll restore your lost data – immediately.

Crashed Thecus – possible causes

• Hard drive failure – or multiple drive failure with RAID
• Overheating, causing hard drive failure
• RAID rebuild failure (all models with multiple drives)
• RAID expansion failed
• RAID migration failed
• Firmware update failure or firmware corruption, causing loss of access to device or data
• File system corruption
• IT Admin or user error (the leading cause of permanent data loss)
