Bad hard drive or bad motherboard
Those units die from time to time especially the harddrives due to
continuous usage.
Your best bet is a harddrive duplicator which are pretty affordable,
and that should do the job, or you can have a telephone shop order the
harddrive for the unit which probably wouldn't be cheap.
I've worked on those before and the harddrive duplicator usually
works if the drive can stay spinning long enough to complete the process.
