Ok, here a small setup.

I create a random file with roughly size of 5MB:
$ dd if=/dev/random of=archive.dmp bs=1024 count=5120
5120+0 records in
5120+0 records out
5242880 bytes transferred in 0.174116 secs (30111397 bytes/sec)

Then a tar the file (with or without blocksize set) to tape:
$ sudo tar -cf /dev/sa0 archive.dmp
$

After that I try to read/list the tar from tape with tar -t:
$ sudo mt -f /dev/sa0 rewind
$ sudo tar -tf /dev/sa0
archive.dmp
tar: Unrecognized archive format: Inappropriate file type or format
$

I get strait away the "Unrecognized archive" message.

But when I extract the archive from tape, it works perfectly:
$ sudo tar -xvf /dev/sa0
x archive.dmp
$

I have tested this with libarchive and tar from RELENG_6 and RELENG_6_2.
No problems with libarchive and tar from RELENG_6_1.

If you need more (debug) info, let me know
