Disk Management?
If not, try that first. Control Panel > Administrative Tools > Disk Management. See if the drive is listed there and if so what state it is reported as.

I installed a second hard drive in a
Dell Demension e521with a windows XP operating system. I followed the instructions for setup on the Dell site. The drive is showing up in the hardware manager but is not showing in My Computer. Any recomendations?
