Hi, I've been using 2 SATA drives as storage for a while now (about 6 months to a year.) Just yesterday my PC has been hanging on startup. I realised quickly that it was not detecting the SATA drives and that was causing it to hang. I think it must be the SATA controller on the motherboard (Asus P4P800 SE.) The drives are Maxtor Diamondmax 10. I'm about to try them one at a time then try them on my other PC and see what happens, will report back with more details.
