I'm a newbie to this forum, 1st run. We've had a server configured with two arrays on a adaptec controller which had a drive fail a couple days ago in array #2 (RAID 5), changing the array status to critical. I purchased a couple replacement drives, same model #, manufacturer (FUJITSU HD MAJ3364MC). After inserting the new drive and performing a rescan, the drive capacity on the new replacement drives (I tried both) are smaller than the original capacity for the installed drives. Capacity on new drives are 34732 MB and the installed drives have a capacity of 34858 MB. It appears this prevents me from assigning the new drive as a spare to array #2, because the new drive disappears when trying to assign as a dedicated spare. If assigning to array 1, the new drive's capacity is larger and remains active to be assigned as an active spare..
Does anyone know if the capacity can be resized on a new drive by performing some type of low-level format, or sector block size assignment. I'm using the software included with the controller Adaptec CI/O Management Software, version 4.01.
Note: I did try a low level format using the Adaptec software, but the option sets were very limited, Verify Disk, or Low Level Format, no additional settings.
