I have an older Hewlett-Packard "Colorado 250MB" internal tape backup drive that I would like to install in my new computer.

The problem is, I have no installation manuals to follow.

I physically installed the tape backup unit into my computer.

I purchased a "ribbon" cable that could connect to both my 3-1/2" disk drive and my tape backup unit.

When I connected everything up, my 3-1/2" disk drive no longer worked and the tape backup unit failed to work too.

Am I doing something wrong here??

Are the 3-1/2" drive and tape backup unit completely different pieces of hardware??

I'm running Windows 98.

Any help would be greatly appreciated.
