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.
