I have a brand new ATL DLT8000 run NBU 3.4 SUN 8. A DLT
technician told me that if you set it too low the head will be
worn out, but if you set it too high you may get read/write
error (not sure with version 3.4 but 3.1 it did). Questions:
If we don't setup the frequency for the drive cleaning the NBU
will clean drive when it required cleaning or not? If not what
number should be? Any information is appreciate.
