You would have a SATA drive which would be compatible with any modern desktop.
1) remove SATA drive
2) remove the adapter if there is one on the end of the drive
3) Power down a PC and open the case
4) attach the data and power cables
5) bootup and copy data to another drive or DVD
I've been using this BlacX for several years. Simply plug into a PC, then slide your 2.5" drive into it, turn it on and it shows up in Windows. No need to buy another SATA data cable or open up a case.
