Advice for Raid recovery
Posted: Wed Jul 22, 2009 10:01 am
Hi there,
Hope someone might point me in the right direction.
Here's my situation. I have a Highpoint 2680 sata 8 chan card, with 3x1Tb disks in raid 5. This was working perfectly. Then, I added a disk using the online capacity expansion tool OCE (software util) which was running fine for about 20 mins, where I could still access the disk in windows. After this, the O/s locked up (I was running windows 2008 r2 x64). After I hard reset, which was all I could do, the system booted back up, I checked the raid util, which had restarted the OCE process automatically. However, this time the disk was inaccessible in windows, just showing as a RAW partition. I contacted Highpoint who told me I cannot cancel the OCE, I can only pause it.
Now I reinstalled my O/S in case this was causing the crash (which happened about 20 mins into each attempt) and the same thing happened, so I can only assume its an issue with either the controller and the disks, or the util and w2008 r2.
So now I have booted up into Windows 7 32bit to test, I thought before I go any further I'd try and see if I can recover any data. So with the additional disk unplugged I've run a scan using R-Studio (still running, its a 2TB GPT partition).
I ran a short scan (cancelled part way through to see if it had found anything, which it had) and the text files were ok but the jpgs i tested were corrupt. I've yet to test any larger (video) files I recovered.
My question, is has anyone experience with this type of scenario and what would your next steps be? Try and continue with the scan, or attempt to do the rest of the OCE before recovering any files? I am just unsure of exactly what the nature of the partition is considering its probably part changed by the raid migration (or is it, considering the test scan seems to have partly worked). Because of the size of the partition, its probably looking like a week just to finish the first quick scan so I thought I'd seek advice while I'm waiting.
Hope for some help,
Many thanks in advance.
