I am addressing the device via /dev/nrsa0 and it works ok (I can push to tape and extract) except that I am only getting about 20 gig of data onto a Tape marked 35 Gig Native / 70 Gig compressed. I need to state here that the data being loaded onto the tape in heavily compressed RAR files. Each file is over 1 gig each in size and I am using the tar command to perform the backup. About 18 files in total. tar -cv -b 64 -f /dev/nrsa0 filename to push the files on to the tape. I have confirmed the lights on the drive correctly identify the tape and have tried both compressed and uncompressed format density override just incase that was adding something strange. I have tried two tape drives with brand new media in case that was the problem. Nothing made a difference As of yet I am at a complete loss to explain what I am seeing. Can anyone offer any suggestions. Thanks in advance Matt Villion To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
