I need to put a nee harddrive in my dell pc due to failure of the old one. My question is when i pulled the old harddrive out it says its an enhanced IDE. when i put ide into dabs it brings up 3 ide as well as ATA100 & ATA133. Am i correct in thinking these are the same thing just different names from manufactures. The important question is can i put any of these in my DELL P.C?. Its a DELL dimension 8300 with 80GB western digital harddrive. ps harddrive direct from DELL are a ripoff.
