I think i see the different ones SATA ATA and IDE... i bought a SATA one and found out that doesn't fit my 44-pin HD...
(I take it SATA is too advanced for my poor onyx toshiba 30 GB) so i guess we go for ATA or IDE? what do you think? thank you guys very much for the quick answers... its frustrating when you're so close to fixing a problem...and then its after hours and comp usas and other computer stores are CLOSED!@
