I haven't seen anything like that, at least in many years so it probably is 
hardware related - but make sure your software is up to date.  As a workaround, 
you might try using rsync with the --bwlimit option to limit the speed of the 
transfer - and the -P option so you can restart a failed transfer from the point 
it stalled on the last attempt.
