Does any one knows how to restore lost storage from RAID 5 (with 2 Hard drives)
explain when I installed Windows XP Pro the RAID was working fine hard drive
storage was visible and partioned all of a sudden RAID drive dissappear and
no longer Accessible and do not know how to restore it. I am not sure if
happened after started installing service packs 1 & 2. another things that I
have noticed is that IRQ used when first installed was 15 now is 5 when
ADAPTED SCSI CARD boots. used to show IRQ 15 now is IRQ have no idea what's
going on.

TIA

RAID 5 needs a minumum of 3 drives. Did one of the drives quit working or
did you setup a different RAID configuration with 2 drives? With 2 drives
you could use RAID 0, 1, 0+1, 1+0 or jbod.

Thanks for the input, it was working fine on fresh xp pro installation it
just dissapeared after service packs 1. and the answer to your question is a
RAID 5 but only have 2 20gb hard drives SCSI (0,1) and I don't think drives
or one of the drive died it has to be something with settings or mounting
drives.

Tnx any way.

As I stated before if you have 2 disks you never had RAID 5 setup. It is
impossible. RAID 5 works by calculating parity. There has to be at least two
disks to calulate parity and another disk to write the parity to. You have
to figure out what you actually had setup before anyone can help you.

Kerry is correct. You do not and can not have a RAID 5 array with only
two drives, it is impossible.
