Is this happening with this one tape only, or all tapes you try in this 
particulat drive?

If the problem is only with this tape, is the tape old and been used a 
lot?  If so, then the tape has reached/passed the end of it's usefull 
life.  If this tape drive is in a library, check the library for events it 
can provide more info.

LTO tape drives track the number of errors, and I think tape usage, 
per-cartrage and will throw this error if the tape falls below a quality 
threshold.  I think the usage counts are written into the RFID that is 
inside the cartrage.  When we get these messages we "retire" the tape.

Hope this helps.
