Raid Question
LJA 25.06.2007 19:45:00
Sorry if this is in the wrong forum But I am hoping someone can help.

We have a raid 1 setup through our Fastrack controller. 1 drive failed so we
replaced it with a new one exactly the same. The raid begins to rebuild but
fails at 15%. I am afraid to do anything aggressive with the remaining drive.
My question is, if we change the controller from raid mode to native mode in
the bios will we lose the info on the good drive? My thinking being that if
the drive will boot we could mirror it in SBS for now so we at least have
some redundancy.
Thank you
Lee

I think my first call would be to the company that makes the Fastrack
Controller and get them to assist you.

I'm thinking switching modes on the controller probably wouldn't hurt the
good drive, but I'd get it straight from them

Make a BACKUP before you do anything.

I have a server that does exactly the same thing, FastTrack RAID-1,
drive 1 failed, replaced it several times with new drives, RAID will not
rebuild for anything. It won't ghost either, but I suspect that it's
because the drive is setup as Dynamic instead of BASIC.

Call the vendor and ask them, different revisions of the BIOS result in
different things happening.

Before the data gets away from you I would do the following - get it onto a
backup USB drive.

Here is what I usually do when a broken RAID device is involved. Use your
favorite disk image / file recovery tool. I've had good results with Iolo's
Search and Recover but there are lots of other good tools too.

Then with your data secured, there is time to play with RAID controller
hardware. Best of luck getting the data secured.
