Great, thanks. That's one down. Does a cable exist that links multiple SATA HDDs or is that a bit of a pipedream?
Edit: it looks like that's a SATA 3 cable. Will that work with a SATA 2 drive like mine?
Sorry, I don't think such a cable exists for your purpose.
The SATA 3 cable is backwards compatible so it will work on SATA 2 drives.
