Questions about switching Hard Drives

I bought an eMachine a couple years back, now the warranty will not cover nothing that wrong with it. my question is can i switch the HD out of the emachine and put it in an old compaq i have. the compaq works but just has 4 GB HD in it.

 

First find out who made the drive for Compaq, I had to use the wd software on an old compaq drive to re-write it there's something on it for compaq id's. but give it a try. i think i redid the sectors to wd.

cheers

 

A 4GB hard drive? You'll have trouble fitting Windows on it. I'm not sure a drive that old will even connect to the eMachines.

 

thanks for the info. i will check to see.
