I have a power failure and when power was restored, I got a LM error message. I spend one hour with customer support going through all the routine and it was determined that I needed to get a new unit. I need the data. 650 GB. Stupid me thought I could use this as my primary NAS. Now after taking the unit to a pc shop to take of the data, they were not able to read the "Raw " data on the drive. With a linus program it was possible to see all the sectors but the important one is not readable on both drives. it wants me to reformat everytime which I don't do. Is it possible that both drives are damage? I believe it is the controller since the unit would no longer shut down and the fan was running faster. The cost of a data recovery service is very expensive. Any suggestions? I have tried everything I know including recovery software and so has the PC shop
If you are planning on using data recovery specialists I would suggest making sure that the company know how to work on RAID storage products (it why we recommend drivesavers).
To answer your question I would try Ubuntu or Knoppix:
root@linuxmachine:~# mount /dev/sdb4 /mnt/data
mount: unknown filesystem type 'linux_raid_member'
root@linuxmachine:~# mount -t xfs /dev/sdb4 /mnt/data
root@linuxmachine:~# ls /mnt/data

You can, but you still want to have backup.
