HDD Disconnect automatically when format to be completed

Hi!.. I want to ask you guys… My Mother’s laptop, A-Note C-8226, use the WD1200BEVS 2,5" HDD, one day the OS Error when booting and must be re-installed, when i try to re-install the OS it says there’s a problem… idk what… i forget… Then i dismount the HDD and try to install the OS from my sister’s laptop… (the OS is windows 7 and i’ve found the way to install to USB HDD), the GUI to install to USB HDD says that i must have a partition with at least 15GB of free space, i make a 50GB partition for the HDD, then i format the partition, the HDD disconnect when the format to be completed, so i re-format it again… it do the same thing everytime the format to be completed… so… do you think… what is the problem?

Maybe you should try contacting WD’s Technical Support about this. You can do so either by phone or email.
