Hi there. I wanted to add an extra hdd to boost memory on my Compaq sr1303wm pc and was advised to use a sata disc. That's when my troubles started. I bought a Samsung hd321kj. By chance, when looking for sata drivers I found that there were endless compatibility problems recorded with sata discs and the OEM mobo (A7V8X-LA) that is in the sr1303wm. I returned the disc the next day (unused) for a refund. I have reverted to looking for a pata hdd but am worried what size disc I can install without address/capping problems. Will the sr1303wm accommodate a wd320gb eide hdd without hassle? I am not too fussed about speed but need good reliable storage. The compaq has xp at sp2 level. If someone has a solution to the sata problem I'm willing to have a crack at it with a small inexpensive drive but the omens don't look good - meanwhile any info on pata limitations/compatibility would be welcomed. The alternative woould be to go for a usb external but the desk starts getting crowded then.
