Hallo skunks,

I have a 500Gig WD laptop HDD - SATA which I use with  a usb powered external casing.

Problems is, the HDD keeps disconnecting when in use. This has become very annoying.
Or sometime it disconnects when I have plugged it into my PC and leave it idle for a while and resume using it.

What can I do to stop this? What could be the problem?

Thanks,
//James
