I have a few differnt drives that are IDE after pluging in the IDE cable an removeing it. A pin falled out of the drive where the IDE Cable plugs in. This happened to three drives, are they bad?
So, the same pin fell out on three drives? Hmm, that's quite strange and quite unlikely to happen. Was this all with the same IDE cable? I think I'd replace that cable.
By the way, are you looking carefully at the connectors on the cable and the hard drive when you connect a cable to be sure you are trying to force the cable connector on upside down?
Also, are being careful when removing a cable to not cause undue stress on the pins by pulling the cable straight off as nearly as possible?
