I am sorry if this was recently covered, but I am still a bit
confused.   I have some classes which backup highly compressed data using
using non-hardware compression.   It seems I usually get about 40G/tape,
which is right on target, however, many of these tapes used to be used by
DLT7000 drives, and it seems that I can't write more than 35G to them:

Example

DJH558  DLT      TLD      0       41     -       3     39195823 FULL
DJH565  DLT      TLD      0       4      -       3     39184084 FULL
DJH566  DLT      TLD      0       23     -       3     39380439 FULL
DJH568  DLT      TLD      0       56     -       2     39337074 FULL
DJH578  DLT      TLD      0       7      -       3     39258494 FULL
DJH579  DLT      TLD      0       14     -       3     39333859 FULL
DJH582  DLT      TLD      0       30     -       2     34462386 FULL
DJH597  DLT      TLD      0       25     -       2     34432524 FULL
DJH607  DLT      TLD      0       58     -       2     39227907 FULL
DJH620  DLT      TLD      0       9      -       2     34373541 FULL

Do I need to manually override the density for all these tapes, or is
there an easier solution?

Thanks,

Jon
