We have a user that has gotten a receipt printer that connects to the PC via a serial cable. The PC she has doesn't have a serial connection so I was going to just give here a spare PC that does have it. Instead of having to reinstall all of her programs and configure her settings, I was wanting to just swap the hard drives. Both PCs are Dells, although not the same model, and both of the hard drives are Western Digital. The current one is a WD2500AAJS and the spare one is a WD5000AAKX. After putting the original hard drive in the new PC, it boots to the Windows 7 splash screen but freezes after a few seconds and reboots. Is there something I can do to make this hard drive work in the new PC or do I need to reinstall everything on the new PCs hard drive?
