Access data on NTFS disk (Raid 5)
Hi there,
I am trying to access data that is on a Raid 5 array in Ubuntu... There are 4 installed disks (250gig disks) - 3 of which are setup as a Raid 5 array (the 4th is active but unused). These show up as one large drive (498gig).
I have had an issue with the drive where it is no longer allowing Windows to boot - I receive a disk read error on boot (so the OS does not load, obviously!) - what happened was basically I unplugged then replugged in one of the disks which affected the array... I physically reconnected everything as it was, I then had to 'reactivate' the disk in the Raid BIOS... at that point the array seemed OK, was the right size, etc (and was listed as "Optimal" in the Raid BIOS) however, the problem with the disk read error persists.
I have started the machine using Ubuntu v9.10 from a CD (non-destructive mode) and it shows a disk of the right size (ie: on the desktop and in Nautilus it says "498gig Filesystem" ). However, in Nautilus, the disk appears empty with no folders or files on it (even with hidden files shown).... If I view 'Information" for the disk it shows 67gig used space and 399gig free space (which is correct). Also, if I view the disk in Gparted, it shows a disk with about 67gig of used space and 399 free space on a 464gig disk (with 8gig unallocated).
One more thing.... when I try the command 'sudo dmraid -tay' it says that there is no raid disk (there are in fact, no drives plugged into IDE or SATA slots - all disk are plugged into the RAID controller card).
Anyway, at this stage, I just want to copy the data to a single hard disk if possible and move on.
Can anyone please advise on what I could try at this point. Hopefully, the data is not lost!
Thanks in advance for any help.
Cheers,
Jack.
