Recently I ran into booting issues with windows 7 on my Acer Aspire S5 ultrabook. Before bootup, the system indicated that one of the physical disks (the ultrabook has two 128 GB SSDs in preinstalled RAID0 configuration) has problems – and on booting up windows goes into the blue screen of death mode.
I basically want to recover my data from the disks before reformatting these and reinstalling Ubuntu.
Using the USB stick, I was able to start Ubuntu (without installing it), and am able to see both these disks (and both these are showing as healthy, though with bad sectors) when viewed using 'disks'.
The output of the fdisk -l command is as follows:
ubuntu@ubuntu:~$ sudo fdisk -l /dev/sda

I tried mounting the raid (which is based on Intel MATRIX Raid) by using 'dmraid -ay'
ubuntu@ubuntu:~$ sudo dmraid -ay
ERROR: isw: wrong number of devices in RAID set "isw_bbdaaaifgc_Aspire S5-391" [1/2] on /dev/sdb
RAID set "isw_bbdaaaifgc_Aspire S5-391" was not activated
Additional inputs:
ubuntu@ubuntu:~$ sudo dmraid -r
/dev/sdb: isw, "isw_bbdaaaifgc", GROUP, ok, 250069678 sectors, data@ 0
How do I get the disks to mount in the original RAID0 configuration?
