  For most tar's "directory checksum error" normally means that the
blocking factor during read was not the same as during write. Check out
the documentation on the tar "b" option on both platforms involved, and
select a block size which is compatible.

  If you only get "directory checksum error" at the *end* of the read (t
or x), i.e. the first files are OK but the last (few) not, then probably
your writing tar is broken. All blocks in the archive should be the same
size, but some broken tar's truncate the last block. You can workaround
this by piping the output to dd(1) with "conv=sync" (and of course the
right "bs=").

  Hope this helps.
