Thanks for the info, this drive has a very thin connector strip, like where a PCB edge would slip in, on other machines the IDE connectors have been a lot bigger. Is the one that i have an EIDE? hope i have made sense.
I think the best bet is to take the drive to a decent retailer and ask them to identify the interface and sell you a USB adapter for it. These are common for the older mini-IDE interface which is a strong possibility for a drive of the capacity you have
The suggestion from snurp seems to be based on assuming older 3.5 inch IDE drive and a desktop computer.
