Rebuilding Raid with GPT Disk order known
Posted: Sun Nov 15, 2009 6:46 pm
Hi,
I am kind of lost. I had an adaptec 3805 raid 5 with 4 disks. I accidentally deleted the good array, so all disks are operational. I know the disk order, at least i know which cable / channel went to which disk.
Boot disk was separate plain sata, so no boot from array.
I am trying to rebuild a GPT partition and tried to follow the ntfs tutorial but got lost.
my stripe size was 512 (thats what it said in teh adaptec boot config tool), does that mean block size = 512 as well ? (I ask because some other partiton tool reports stripe 512 when block size 1024 is entered)
I cannot find $.M.F.T on any of the disks. I find the EB 52 90 4E 54 46 53 20 20 20 20 and 33 C0 8E D0 BC though.
how do i know whether my adaptec raid is left sync/async or right sync/async ?
Is there a difference between entring the offset or will a full scan reveal the same info, it just takes longer ?
What would I be looking for on a GPT partition ?
cheers
