Those old 12.5mm high drives don't fit anything current.
The hd from the 7400 is a bit thicker than other laptop drives. I tried to use the 7400 in a Dell Inspiron 1000 but it would not fit the compartment. Also i purchased 2 diff 2.5 external drive usb housings and the 7400 drive was too thick for them. I hope one you laptop gurus can advise me. I am considering purchasing m700 with no hd from an e-bay seller and would like to use the 7400 drive in it. Anybody know for sure?
