I have added a Sony SDX-420 ATAPI tape drive to a FreeBSD 5.2.1-RELEASE system. The tape successfully does a dump and restore on this system but when the tape is taken to a Sony SDX-400 SCSI tape drive on a FreeBSD 4.7-RELEASE system, restore insists that the tape blocks are 512 bytes and this is not a multiple of 1024 (the tape was created with a -b 32). I have then taken the backup from the SCSI drive (where it reads) and attempted to read it on the ATAPI drive; the result looks like: monster# mt -f /dev/nast0 status Mode Density Blocksize bpi Compression Current: 0x01:X3.22-1983 512 bytes 800 0x1 ---------available modes--------- 0: default variable 0 none 1: default variable 0 none 2: default variable 0 none 3: default variable 0 none --------------------------------- File Number: 0 Record Number: 0 Residual Count 0 monster# mt -f /dev/nast0 rew monster# restore -t -b32 -f /dev/nast0 Tape read error while trying to set up tape continue?
