you didn't tell us much about your system -- mobo in particular. assuming we're not talking something exotic, e.g., like SCSI, I think the only real issue is the HD size (in terms of MB) limitations of older mobos.
other than speed and size, they're all pretty much the same. I happen to like seagate. --fj
According to Belarc and an application named HDD Health, my H/D's days are numbered. Also, the fact that my computer screen has frozen more times than I can remember within a 1 1/2 year period, resulting in several H/D reformats, seems to confirm the statistics.
I want to replace my failing 40GB internal H/D with a 60 or 80GB one. Will that make for incompatability problems? Where do I find the specifications of my present H/D in Windows, so that I purchase one that configures with my pc?
