Hi all:

The situation: I did a copy yesterday, this copy finalized correctly 
and I extracted files correctly from it. My surprise arrived when today 
I attempt to recover from this tape and it shows me a 
mesage "Input/Output error reading header". My tape device is an hp-
t20i scsi but i don't understand why don't goes correctly if yesterday 
i extracted files correctly from it. The difference is that the tape 
has been ejected and inserted. 

Can help me someone?. Is normal this problem?.What can i do for not 
happen again?.

Thanks, Raúl.

PD: Excuse my english level.
