- 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.
