Hi all. My partner hasn't used her pc for about a year now as we just use mine and she was having trouble with her hard drive (it just said something along the lines of "boot device not recognised" or ".....failed to load" or something along those lines). We're now giving the pc to a relative (minus the hard drive). Since we wanted to get rid of the HD, we wanted to zero-write it first. So, to do that, i took the HD from her pc and plugged it in to mine to do it from there.
Here's the bit i don't get: I've got Windows 7 and the other HD has XP on it. After plugging it in and forgetting to make sure the boot sequence wasn't changed, i turned on my pc and XP starts loading up. What i want to know is how come it wouldn't work on her computer, (to the point where we thought it was a faulty hard drive because this is the 2nd one she's had where it happened) but it works on mine?
Since I'll be giving my uncle the old pc, i'm worried that it'll show the same problems for him if it wasn't the hard drive that was at fault but i have no idea what it could be.
So what do you think? Is it the hard drive, a connector, the PSU, the motherboard?
Any help would be greatly appreciated.
P.s. when the hard drive was plugged in to my pc, i ran error-checking on the disc from Windows 7 and it found and fixed an error on it; i think it was just a bit of space that was free but incorrectly marked as allocated.
