how big is the one drive it's recognizing?
100GB?
if yes, it means you wiped out the partitions existing before the re-format
if no
you need to go into the BIOS of the system, see if it shows both
if not
open the case and make sure the cables are connected securly
if not again
reset the CMOS
I have a 40Gig & a 60Gig hard drive installed in my tower. I had to reinstall XP and now my computer only recognizes one hard drive. How do I get it to recognize both.
