I lost another HD last week, . . . .External< I ain't bragging about going through two hard drives in two years, but this was only a year old. I guess I put it through hell,

Unfortunately I can't run out and buy a new one like you rich guys but,

I would like to know if anyone has ever tried to connect two towers with a USB connection?
and using the second computer as a data back up.

I didn't google it as I figured you all couldn't wait to express yourself in a general chat way.

Has anyone ever tried a data recovery service they look expensive even though they don't charge if they don't recover ?

"How can I connect two PCs to each other with USB?
A5: You need a specialized USB peripheral known as a USB bridge (sometimes called a USB to USB adapter) to do this. Without a USB bridge, connecting a USB port of a PC directly to another PC's USB port can damage the computers. "
You would risk damage to either one or both power supplies and/or the 5 volt circuit on the motherboards.
You'd be better off using a cross-over or null network (CAT 5) cable. About $10-$15
USB bridge

Thank you Sir,

I have an box with a 2-port Biotronics parallel Switch Kit here, (Belkin) Cable included, it's quite possible that it has something in it that might meet the requirements, it's never been used, but I no nothing about it, I'll check it out and see if there is anything interesting in it, what I don't want to do is screw anything up. So unless you post back I won't be doing anything for a day or two.

That will not work. That is simply a switch for using one USB device between 2 computers.
