Using the 1.3.10 CYGWIN and tar 1.13.19 installed via setup.  We had a DLT4
tape with a gzipped tar archive of 2271527848 bytes.  Using the tar command
to list the contents of the tape we got the following result:

$ tar -tvf /dev/st0
-rw-r--r-- sdbadm/dba 2023709448 2002-05-01 14:51:16 {file name removed)
tar: Skipping to next header
tar: Error exit delayed from previous errors

On restoring the archive anyway, it restored 2023709448 bytes.

This was also tested using MKS Toolkit's VPAX.  VPAX read the archive as
having the correct number of bytes and restored the file with the correct
number of bytes.

The system was running Windows 2000 Advanced Server with SP2 and SP2SRP1 and
all other latest updates.
