Mike,

I think that you are not looking at the hard drive itself but at a
"caddy". The caddy can be opened and the hard drive is inside it.

All 2.5" IDE hard drives have a standard (with one exception) interface
connector. It's 44 pins, then a gap, then 4 more pins. The 44 pins are
the standard 40-pin IDE interface (same as on a desktop 3.5" drive, just
with a different connector) and 4 power/ground pins. The extra 4 pins
are used for drive configurations (master/slave/cable select). The only
aspect of this interface that is totally non-standard is the use of the
4 pins for master/slave/CS configuration, which varies by drive model.
Otherwise, everything is standard, going back to at least the early 1990's.
