hello, i have a HP SureStore DAT40i (HP C5683A C908). it is a DDS-4 drive that purports to write to smaller formats such as DDS-2 or DDS-3. my problem is when i try to write to a DDS-2 tape. in its default configuration, i cannot write the full capacity of the tape (4 GB uncompressed). with hardware compression turned on, i get about 3.6 GB on a tape. mt status shows: # mt status Mode Density Blocksize bpi Compression Current: 0x26:DDS-4 1024 bytes 97000 enable ---------available modes--------- 0: 0x26:DDS-4 1024 bytes 97000 enable 1: 0x26:DDS-4 1024 bytes 97000 enable 2: 0x26:DDS-4 1024 bytes 97000 enable 3: 0x26:DDS-4 1024 bytes 97000 enable --------------------------------- Current Driver State: at rest. mt density shows: # mt density DDS-2 Using "DDS-2" as an alias for 0x24:DDS-2 however, status immediately after the density setting shows no change! is the tape drive smarter than i think it is but doesn't show the correct density setting? thanks, adon To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
