I'm sorry this is a bit off-topic, but large raid sets need big backups ;-)
My HP SureStore DAT24 stops after writing 12 GB of data to a DDS-3 tape. I
suspect there must be something wrong with the compression. To verify this I
need some additional information:

Strange.
I think latest Linux SW-RAID is working pretty good (ever wondered why it is in

In contrary, there are "released" (or at least BETA) versions which are quite
more complicated to install, needing scripts, being unable to have root on

Alan Cox suggested porting up to 2.3.x (there are some substantial
