No problems with libarchive and tar from RELENG_6_1. I did.. tar -zcvf /dev/sa0 /boot tar -ztvf /dev/sa0 tar -b 1 -zcvf /dev/sa0 /boot tar -b 1 -ztvf /dev/sa0 tar -b 20 -zcvf /dev/sa0 /boot tar -b 20 -ztvf /dev/sa0 tar -b 128 -zcvf /dev/sa0 /boot tar -b 128 -ztvf /dev/sa0 And they work. The example you gave failed however, so do.. tar -b 1 -cvf /dev/sa0 /boot tar -b 1 -tvf /dev/sa0 tar -b 20 -cvf /dev/sa0 /boot tar -b 20 -tvf /dev/sa0 tar -b 128 -cvf /dev/sa0 /boot tar -b 128 -tvf /dev/sa0 Using dd to feed tar does work though. (I think this agrees with Robin's=20 findings although the fact that it works with -z is curious) [cain 17:05] ~ >mt status Mode Density Blocksize bpi Compression Current: 0x40 variable 0 disabled =2D--------available modes--------- 0: 0x40 variable 0 0x1 1: 0x40 variable 0 0x1 2: 0x40 variable 0 0x1 3: 0x40 variable 0 0x1 =2D-------------------------------- Current Driver State: at rest. =2D-------------------------------- =46ile Number: 0 Record Number: 0 Residual Count 0 This is a Tandberg TS400 (LTO2 drive, LTO1 tape) =2D-=20 Daniel O'Connor software and network engineer for Genesis Software - http://www.gsoft.com.au "The nice thing about standards is that there are so many of them to choose from." -- Andrew Tanenbaum GPG Fingerprint - 5596 B766 97C0 0E94 4347 295E E593 DC20 7B3F CE8C --nextPart3846374.yCMSWuj31v Content-Type: application/pgp-signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.5 (FreeBSD) iD8DBQBGZmYC5ZPcIHs/zowRAhuLAJ95SVOc5BGHBbQrdnxmNa9n3V8bRwCgh+0i z9DPNKt3pbQhP93QtzD+AlI= =uTvR -----END PGP SIGNATURE----- --nextPart3846374.yCMSWuj31v--
