Hello,
>This version adds sg_rmsn to read media serial number(s).
It appears that this doesn't quite work as I had hoped.
Ideally, should it not work upon every drive in which sq_inq reads the serial
number?
SUSE 9.2, vendor kernel:
root@emitestmachine 09:22:57 ~ # gcc -v; echo "----------------------"; sg_inq \
-v /dev/sg0; echo "-------------------------"; sg_rmsn -v /dev/sg0
