    My Qnap TS201 has failed. the drives are OK according to Qnap who remoted into the system to see what the trouble was - two discs in Raid 0.

    All the data was backed up onto another NAS with one exception.

    As Qnap insist that the drives will be OK, how can I read the drive on a Windows PC please? I have a USB Sata dock. I tried the Diskinternals Linux Reader and it shows the expected folders but each one reports as empty???

    Fingers crossed.

    many thanks

    Since they were in RAID-0 that means they they must be read together in a compatible RAID-0 system; your best bet is to put them into another working QNAP TS201 and hope for the best. This is the problem with RAID-0 configuration, both drives must be functional and must be setup in RAID-0 to access any of the data since the data is stripped across both drives. RAID-1 would have been a better choice as then you can use either of the two drives to access the data easily from any other PC or dock.

    By the way, whats wrong with the NAS? Its odd that its failed but they were able to remote in and check the drives.

    The tech from Qnap simply said that as the drives were OK then the data would recover in a Linux reader. oh well.

    Reason for raid 0 was that the NAS was actually used as a backup initially and therefore the capacity was important.

    Following this problem I moved to Netgear ReadyNas and use the data stores in Raid1 with backup (of the infrequently changing data) manually put onto ReadyNAS in raid0.

    Issue with the Qnap was that following a power failure it would alternately only see ONE of the drives and not the other, and after a reboot the other way round.

    I did not dare to mess with it and contacted Qnap tech who dialled in and spent a while meddling to conclude that the hardware (not the drives) was faulty.

    I still have the hardware AND the drives. Tried full factory reset of the qnap with no change to the situation.

    If you want the data back your best bet is another QNAS TS201 with RAID-0 setup and then swap your existing drives into it.
