Actually I suspect you have been lying in a number of places and ways. Perhaps unintentionally :)) What tape drive do you really have? If I recall correctly, the SureStore-1200 is a DDS2 (DAT-2) changer and you were using a reasonable (3.9GB) tapetype definition for that. But you were using 125M tapes, DDS3 tapes that should not work in a DDS2 drive. Actually, has anyone ever tried that? And for sure, even using a 5M longer DDS3 tape with a DDS2 drive, I don't think would not get anywhere near the 8GB capacity you seem to be getting. Unless you can write to DDS3 formula tapes in a DDS2 drive AND we consider your other lie :) >> 4.) is hardwarecompression active in your tapedrive? > No, disabled by using device /dev/rmt/0bn > (b= berkley mode n= no compression) Based on device name I'm guessing this is a Solaris or HP system. In either case, "n" refers to No Rewind, not no compression. By chosing the 0 device with no density modifier (like "l", "m", ...), you have elected default compression, which generally is on. So maybe, if you are using a DDS2 drive, a DDS3 tape, no software compression, and hardware compression, you can get 8+GB of data written. What are you actually doing? BTW using the Berkeley drive options is not recommended. -- Jon H. LaBadie [EMAIL PROTECTED] JG Computing 4455 Province Line Road (609) 252-0159 Princeton, NJ 08540-4322 (609) 683-7220 (fax)
