If you have the EVEREST free application (Ex AIDA32)
from Lavalys.com on your PC then under STORAGE >
ATA it will give you all the info on your HDD. i.e.
maker, speed, cylinders, ata etcetera. I know because I have just checked mine on it and it gives
me ATA100. This free PC information checker is a very handy programme to have on your PC.
