Just bought a My Book Studio and even though the encryption is off it is encrypting the backup which seems to be taking slightly longer than eternity! Also, I started a Quick Drive Test whixh whizzed through to 90% complete and has now hung.
I’d be grateful for any thoughts as to what’s up with it.
Regarding the test hanging on 90%, try using the drive on a different port and make sure that the power cable is connected directly to the wall outlet. Also you can try using a different USB cable.
