External Enclosure works in XP but not in Windows 7

Hi Everyone,

I had built a new system a while back with Windows 7 64-bit edition installed. I used to use XP 32-bit on my old PC, and backed up my files with an external 2.5" hard drive (w/ "Moving Star" enclosure). My issue is: the external hard drive is recognized on my old PC but when I plug the USB plugs into the new computer, it is not recognized. Furthermore, it gives off a constant clicking noise (about 2 clicks/second). This sound/issue is still not seen in the old PC, which still works fine with this hard drive. I've searched the forums for a similar issue, but have not found it/or at least a solution to the problem. Thanks in advance to any advice!

Hi Jibu,

The clicking sound you can hear i would assume is the drive attempting to spin up but is unable draw enough power from the USB port. Hence it never spins up, and as such is not recognised by Win7 when you plug it in to that computer.

This is fairly rare on new computers as almost all computers with USB2 supply enough power on the port.

Are you using a port on the backplate of the motherboard, or one on the front/top of the the case (which runs off a USB header) ??

Can you tell me which motherboard you are using?

Hi Jaffa,

I tried it on both the front and rear connectors, which same issue result occurring both times.
