Hello,
the following is done with: mt V2.5.2, Corinna Vinschen, Aug 26 2013
I have a Quantum LTO 6 Tape Drive (QUANTUM_ULTRIUM-HH6) which works in general with the latest cygwin64. I can use mt to rewind or eject and tar can write and read the tape.
Before starting to write I want to check if the tape is ready with "status", but no matter if the tape is in or not, status always says ONLINE.
Can anyone help, please? Thanks in advance.
