We just upgraded (new, full installation) the O/S on our file server from W2K to X/P Pro.
Our IT consultant recommended that we also replace the two existing, 4 year old, 80 GB IDE hard drives.
We purchased two, new 160 GB drives (Western Digital Caviar - same family as the original drves.
(We use an Adaptec ATA RAID 1200A controller configured as RAID 1/ mirroring.)
We powered down, removed one drive, installed the new drive, powered up and allowed the system to recreate the "failed" drive.
Everything worked fine so we repeated the procedure on the 2nd drive.
However, the system only sees these as 80GB/ not 160 GB drives.
How can we utilize the full capacity?
