To be honest I didnt think you had to get a hard drive that was compatible, but I was reading an ebay listing on a Maxtor Maxline Hard Drive Disk, The guy stated he was selling it because his desktop was not SATA compatable?

Ok so my question is how do I find out if My desktop pc is SATA compatable or better still what HDD are compatable with it?

I have an EMachines 220 UK Purchased. OS is XP Home, 636RAM
TIA
