I got a new external hard drive case and am using an old 20 Gb hard drive, i have an old PC downstairs running XP, and the hard drive will work with that PC no problem but when i try it on my new(better) PC also running XP it tells me there is a a USB connection when i plug it in but it doesn't show up on the PC at al(My Computer)
If i leave it plugged in and just switch off the hard drive it will appear in "My Computer" for a split second, anyone know what the problem might be?
Could it be that the hard drive is old?
Does hard drive speed make much of a difference to the speed of of transfering stuff from PC to hard drive, or is it all down to USB port speed?

Thanks
