Putting COMPAQ hdd into non-Compaq PC, What to do ?

Hello,

I am trying to salvage some data from a Compaq 5192 hdd . I put
the hdd into another PC, and BIOS checks the drive ok. Windows on the
other hand does not recognize the parition. I guess its because of the compaq
paritition on the hdd ?

What I would like to do is to get access to the DATA partition on that hdd, I
don't care if that drive works again in Compaq or not. I just need to move the
data over to another hdd.

What do I need ?

thanks
