I have added a 120GB WD hard drive to a Dell Dimension computer. The drive was recognized through Plug n Play, and is seen in Device Manager. It says "the device is working properly". However, it is not present as a drive in "My computer". Also, putting in a bootable floppy, I do see the drive in FDISK, under "Change Current Fixed Disk Drive". Although, it shows a size of only 49000MB. Any advice would be greatly appreicated.
