We're very sorry!
Probabry it's 10th or 11th Apr, isn't it? I was attacked too, but from outside.
I asked my network administrator about that on 13th Apr, and catched reason. They said that their network equipments had some probrems, and fixed it.

I tried compression option, but It doesn't work well.
I tried ...
No.1 # mt datcompression 1 ... write # mt datcompression 1 ... read
No.2 # mt datcompression 0 ... write # mt datcompression 1 ... read
No.3 # mt datcompression 1 ... write # mt datcompression 0 ... read
No.4 # mt datcompression 0 ... write # mt datcompression 0 ... read
, but can't
'datcompression' isn't correct option ?

I tried, and got error message...
----------------------------------- # ls >/dev/tape st0: Write not multiple of tape block size. <----- ??? ls: write error: Input/output error # ----------------------------------- # cat /dev/tape [inclemental-] Tue Apr 24 03: ...... <----- looks like good! # -----------------------------------
Something wrong?
Thanks, for your help.
