HD-PCU2 cannot be read. Help!!!

[halfbrain]

I have an HD-PCU2 that used to work just fine on my laptop (Win 7 64bit) but when i plugged it in today - it wasnt working.

 

The blue light is still on, I can feel the vibration in the external HD but it doesnt show up in my computer.

 

I looked into the device manager and it wasnt there. I tried a different external HD and it was detected. I tried the HD-PCU2 on another machine and it still cannot be read. This makes me conclude that the problem is with the HD-PCU2.

 

Can anyone help me identify what could be wrong here? Can it be a cable issue?

 

Thanks in advance.

Does it appear in disk management at all (post a screen shot) have you tried a different USB cable?

Nope, it doesnt show. I dont have a spare USB cable so i cant test that now.

its just a standard micro USB type B cable. (used on alot of phones) get one and test it.

Just got a new cable... unfortunately still doesnt work.

then the HDD or SATA bridge is faulty.
