Yes I read you have XP with SP3 but until we know what the original XP was when it was installed, you have to assume it has the 127GB limit on the boot drive.
Why not add your 2TB drive and use that as the data drive?
I have a Dell Optiplex GX620. Specs: Intel Pentium D, 2x80GB SATA II, 2GB DDR2, WinXP Pro (w/ SP3)
I want to replace the current hard drive with a 2TB hard drive. From what I've read, WinXP will support this. Would you recommend upgrading the ram as well? Is there anything else I need to do/get or a hard drive you recommend?
Thanks for your help!
