Hi all,
 
We have just received a new backup tape library with 4 LTO-4 Ultrium 1840 tape 
drives. After doing the first tests, we receive Data errors when the tapes are 
almost full:

\\.\Tape1 moving: fsr 12149 (read): Data error (cyclic redundancy check). 

The problem occurs with different tapes and with any tape drive?
Could it be a misconfiguration in Networker? We are using NetWorker version 
7.4.3.Build.569

Regards,
Andrés
