mohl by jste se svojich pratel zeptat na nasledujici chybu? Objevila se 
mi na jednom linux serveru a mam strach, ze mechanika umira.Cistil jsem 
ji, zkusil nove medium a nic. Par souboru to zapise a pak smrt.

[root at mfgpro zaloha]# cd /data914/bi1/zaloha; /bin/tar cvf /dev/st0 *.bkp
admmodel.bkp
/bin/tar: /dev/st0: Wrote only 0 of 10240 bytes
/bin/tar: Error is not recoverable: exiting now

zajímavé je, že se mechanika tváří jako TR-5 , ale podle mého názoru by 
měla být identifikována jako DAT (DDS-4)

[root at mfgpro zaloha]# mt -f /dev/st0 status
SCSI 2 tape drive:
File number=0, block number=0, partition=0.
Tape block size 0 bytes. Density code 0x47 (TR-5).
Soft error count since last status=0
General status bits on (41010000):
BOT ONLINE IM_REP_EN

dmesg hlásí chyby
