My problem still exists: I can read QIC DC6150 but not DC 6525. I last CVSup'd 3.1-stable on april 10.

The tapes where written under 2.2.7 with "tar -cl". I just tried to write a new tape under 3.1 and write and read it: all operations succeeded without error but with blocksize 512: su-2.02# mt status Mode Density Blocksize bpi Compression Current: QIC-320 512 bytes 16000 unsupported ---------available modes--------- 0: QIC-320 512 bytes 16000 unsupported 1: QIC-320 512 bytes 16000 unsupported 2: QIC-320 512 bytes 16000 unsupported : QIC-320 512 bytes 16000 unsupported --------------------------------- Current Driver State: at rst. --------------------------------- File Number: 0 Record Number: 0 su-2.02# So at this moment, I am able to make new backups and restores, which is the most important thing to me. Anyway I think it would be better, if my drive could read the old tapes, because QIC tapes should be exchangeable between different OSs. Many thanks to everyone contributing to these FreeBSD sources!
