Hmm.
I can only suggest to add debugging output to mt.c:do_dat_compression()
I think the "mask" handling overwrites the cleared flag again, perhaps print out mask[4+2] there to see if the drives allows it.
You were right. I asked one of our C gurus here - he found two bugs in this little function, produced a patch and mt is working now! -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is.
