Dell Dimension with 2 500 GB drives. Win 7 Home Premium 64 BIT
Bios sees both 0 & 1 (cannot select HDD 2 as boot drive if that means anything)
Device manager sees both and as working
Disk Manager does NOT see second drive (scrolled up & down)
Received replacement drive from Dell - no help
Cables and MB connections have been swapped repeatedly - no change
Power connections have been swapped
Any ideas beyond the above?
Just for anyone who might have same problem - I installed an SSD and bingo - both drives popped up. Go figure.
