Cautions to Recover Up To 100% NAS Data

  • Don’t try to repair – Don’t try to repair physically crashed QNAP’s NAS drives. Doing so may further damage the drive reducing the rate of recovery.
  • Don’t use hit and trial methods – Using hit and trial methods to recover QNAP NAS data may result in data overwriting resulting in permanent data loss.
  • Don’t rebuild the RAID configured on NAS – If you’ve configured RAID on your QNAP NAS server and have lost data due to the failure of multiple disks in the RAID array, don’t try to rebuild the RAID. Entering incorrect RAID array parameters while rebuilding might lead to permanent data loss and a reduced rate of recovery.
  • Replace the failing drive – If you observe drive failure symptoms stop using the NAS system/server or replace the failing drive to prevent further damages and permanent data loss from the affected drive.
