It looks to me like you need to be using the 'B' switch to tar. In
other words, substitute 'tar tBf -' for your tar command. Do you still
see the problem? 'man tar' may be of some help; it describes how it
makes tar(1) continue after short reads.

Sorry if I'm way off base here. It's just that 'B' has always
addressed this sort of problem for me in the past.
