Bundle deal Nano & 60 Gb HGST may be a problem

[Digitizer]

Hi
We use the Thecus yes nano's with different hard drives however when we used them with the 7200rpm hitachi hard drives we had nothing but problems ,pc's not being able to find the drive ect ect then when we swapped the drives to 100gb 5400rpm drives they work perfectly every time. It seems the 7200's draw a bit too much juice !
Just thought you maybe would like to know our experience just incase.

How about plug the additional battery pack?
most of 2.5" HDD take 1A power but USB provide 500ma only.

We Tried that didnt help & sometimes doing so rebooted the pc as if the power from the battery pack back fed the usb port ? result instant power off.
However since changing the drives to 5400rpm no prolems at all.
