I'll change my words slightly , because no one has not answered my question
correctly and entirely yet...
What I want to know is how to confirm how much remaining amount is
on each tape media visually and correctly on GUI.
FYI, after one of weekly backup tasks finished yesterday, I could temporarily
find it showed almost its real visible amount at that time, while couldn't do so
this morning.
I've not still known how to fix fundamental issue and been very confused...
Also been concerned about any compatibility problem with my LTO drive
or DP 9.00.
