Single and multi-bit media errors are several orders of
magnatude more likely on tapes than on hard disks.  You
will have to forgive me for not being able to quote chapter
and verse, but as I remember (and my memory is quite foggy,
forgive me), the figures are something like 1 bit in 10^7
for tape media and 1 bit in 10^9 for hard disks.  Perhaps
someone with better (and more recent) data will care to
speak up.

Obviously there is some risk for both media, but the risk
is vastly smaller for hard disks.
