Recovery methods for this NAS
- Deleted files or a reset volumeLogical recovery from drives that still workYes
We image the drives, then search the volume for deleted files and for the volume as it was before a reset. Stop using the unit straight away: new writes overwrite deleted data.
- Failed drivesDrives that click, don't spin or have bad sectorsYes
Each failed drive is imaged on its own. Hard drives that have to be opened go into our clean room, with donor parts matched to the exact drive.
- RAID reconstructionRebuilding the array from its member drivesMain method
We work out the array layout from the drive images: drive order, stripe size, parity rotation and offsets. Then we rebuild it virtually and mount the volume read-only.
- Dead unit, healthy drivesThe NAS itself won't power on or startYes
Your files are on the drives, not in the unit. If the NAS has died, we read the volume straight from the drives without it.
- Encrypted volumes and foldersEncryption you switched on in the NAS settingsNeeds your key
If you turned on volume or shared-folder encryption, we need the password or the exported key. Without it the data can't be decrypted, by us or anyone else.
About this model
- Runs Windows Storage Server from a separate embedded 60GB SSD; the data drives are managed by Windows (Thecus cites Storage Spaces and Data Deduplication), not by ThecusOS.
