Hi all,
Im confused about the capacity handling for DAT DDS2 and DDS3 cartridges.
I defined the following deviceclasses:
DDS2 - for DDS2 format without compression
DDS2C - for DDS2 with hardwarecompression
DDS2 - for DDS3 format without compression
DDS3C - for DDS3 format with hardwarecompression
I filled a tape (devclas DDS3C) with uncompressed data. The data i used
was really uncompressed. For a test i zipped that data and reached a very
good compression rate. The END-OF-Volume was at aprox. 12GB. I reached
the same value when I used the DDS3 devclas.
The same happend when I use the DDS2C class. Only 3.6 GB on different
volumes.
Thanks for any ideas,
Stephan
