Nope, it doesn't work.

# dd if=/dev/sa0 of=/data3/tmp/bla
dd: /dev/sa0: Input/output error
0+0 records in
0+0 records out
0 bytes transferred in 0.005972 secs (0 bytes/sec)
#

When setting the correct blocksize, it does work:

# dd if=/dev/sa0 of=/data3/tmp/bla bs=65536 count=32
32+0 records in
32+0 records out
2097152 bytes transferred in 9.698233 secs (216241 bytes/sec)

This morning I have revert libarchive (src/lib/libarchive) and tar  
(src/usr.bin/tar) back to RELENG_6_1 and surprisingly (or maybe not)  
it works fine now.

Maybe tar doesn't use the -b option when listing the content? (-t)
