I have a MBL which has been running for the past few years in RAID1 without any major issues. However, within a couple of days the network connection to the NAS became unstable and then I could not connect to it. Now I hope that I can recover the data on the disks.
In order to try to recover the data I have followed the first part of the instruction described here:
‘Disk Internals Linux Reader’ and ‘R-Linux’ could not recognize the file system. Therefore, I tried Hiren’s Boot CD, but it gave me the error message: unknown filesystem type ‘linux_raid_member’.
Then I tried the ‘Ubuntu Desktop CD’ as described here: http://community.wd.com/t5/WD-ShareSpace/HOWTO-Recover-files-from-a-RAID-1-mirrored-drive-when-the/td-p/138448
But I received this error message:
‘wrong fs type, bad option, bad superblock or /dev/sdb4, missing codepage or helper program, or other error’.
I have spent a lot of time trying the above and searching the web for other things I can try, but I don’t seem any closer to a solution than when I started.
All input on how to proceed is greatly appreciated.
