I am having problems finding the correct density and length settings. I am using DDS-1 90m tapes. I am using a length value of 295 ft. I found the 'Linear recording density' in the manual for the tape drive(61000 BPI). Here is what happens when I use dump with those values. cyber1# dump 0ufds /dev/nrst0 61000 295 /usr DUMP: Date of this level 0 dump: Mon Aug 19 12:07:04 1996 DUMP: Date of last level 0 dump: the epoch DUMP: Dumping /dev/rsd0s1f (/usr) to /dev/nrst0 DUMP: mapping (Pass I) [regular files] DUMP: mapping (Pass II) [directories] DUMP: estimated 198158 tape blocks on 2.16 tape(s). DUMP: dumping (Pass III) [directories] DUMP: dumping (Pass IV) [regular files] The tape is suppose to store 2GB native and 4GB w/compression. What am I doing wrong? Am I using the wrong units of measure? I checked the man page and a section in a book on 4.4BSD, I thought that this was the correct usage. Any suggestions would be greatly appreciated. David Brockus
