I have two hard disk drives on laptop one of which is full the other empty.When i try to download something it keeps saying hard disk full!?
How can i use the other hard disk drive as the primary one?

I just bought a new StoreJet External Hard Disk and it appears in the "Devices With Removable Storage" category and not in the "Hard Disk Drives" one. I used to have a Toshiba Hard Disk (external) and that used to appear in the Hard "Disk Drive" category on "My Computer". So is there a way to make my hard disk appear as a Hard Disk Drive.

I’ve tried to connect the hard disk drives with adapters. I put a 68 pin to 80 pin adapter, from the cable to the hard disk. My computer detects and works fine with the Controller Card. However, the computer doesn’t detect the hard disk drive. Why isn’t my computer detecting the SCSI Hard disk drives. Does any body know about SCSI Hard Drives? Thanks a lot.
