Hello!
I use a 2GB HP-DAT drive for backup. 'st stat' reports the following:
Present Mode: Density = X3B5/88-185A Blocksize variable
---------available modes---------
Mode 0: Density = 0x00 Blocksize variable
Mode 1: Density = 0x00 Blocksize variable
Mode 2: Density = 0x00 Blocksize variable
Mode 3: Density = 0x00 Blocksize variable
After backing up with the level-0/1 script from GNU-tar I try to
verify the tape (/dev/nrst1)
crw-r----- 2 root operator 14, 17 Sep 21 04:54 /dev/nrst1
crw-r----- 2 root operator 14, 17 Sep 21 04:54 /dev/nrst1.0
crw-r----- 1 root operator 14, 21 Sep 15 08:58 /dev/nrst1.1
crw-r----- 1 root operator 14, 25 Sep 15 08:58 /dev/nrst1.2
crw-r----- 1 root operator 14, 29 Sep 15 08:58 /dev/nrst1.3
crw------- 1 root wheel 14, 536870928 Sep 15 08:58 /dev/rst1.ctl
with tar -tf and get the following error message:
910 : tar tv
tar: read error on /dev/nrst1 : Input/output error
and on the console
st1: 51200-byte record too big
the blocksize for tar (-b) is set to 100. There are no problems with
the same procedure on my Wangtec 525MB tape (/dev/nrst0) but there st
reports a blocksize of 10240.
Any suggestions? The manpage for st(4) says a blocksize up to 64kB is
allowed!
Regards
Lars
