Can't locate my WD My Book 1130 in my Windows Vista

I tried a different computer and it gave me the option to “format” it.  (Not sure if format was the term, but the process before you can start using the drive).  I got scared to try because I fear I might delete the data on it.

I doubt its the cable, but I did at one point have it hooked up to a hub.  But the cpu still can’t read it, whether its in the hub or directly in the computer.

Any other ideas or ways of tricking the system into reading my External!
