Old HDD is already there..... before that i tried to boot, everything went okay - everything was loaded, pc restarted and had info - please wait while windows is set up ur PC - but nothing happened - went off and and have this thing now.

maybe it will help too - prior to my prev post my PC wouldn't load properly - was going into repair mode when attempting to fix - there was error coming up and was saying that disk is corrupted - so i was advised to boot it and install new vista

To determine if that drive can be trusted with data or not DLoad the Free diagnostics from the drive manuf. website...
Follow the instructions on creating a bootable CD and run the LONG test...
