Unlikely. It's an 8086. AFAIK, it's an early XT IDE. One cable - 44 pins.
No power cable.

I can count. It's not the standard 2.5" laptop connector. Besides, it was
a metal housing that was almost impossible to get open. It appears as if
you have a different generation of drive.

I have one and the number of pins does not match.
