Yes. Depending on your motherboard, you may need an HDD with a transfer rate of 6 gb/s. Newer mother boards support models of 6 gb/s transfer rate, however it should not matter much seeing as the mother board limits the transfer rate so:
A 6gb/s HDD will work with a 3gb/s Mother Board(Transfer rate will be 3gb/s) and it will also work with a 6gb/s Mother Board(Transfer rate will be 6gb/s).
A 3gb/s HDD will work with a 6gb/s(Transfer rate will be 3gb/s) mother board and a 3gb/s mother board.
Just buy one that is 6gb/s.

is it a laptop?
Get a new harddirve.
Use a USB to install Window's OS on it and done.
How old is your computer?
you guess right, hard drive may be fried
get a new hard drive
install an OS on it
problem solved
then stick your old drive back in to see if it will detect then, if it still doesnt, throw it away
if it does detect, get important files off it as fast as possible
