I did try specifying tape length using this command line: dump -0uB 3500000 -d 61000 -f /dev/nrsa0 /home the results were impossibly slow (more than 5 hrs for a 9MB dump) and even then we reached the end of tape and got "DUMP: write error 3725120 blocks into volume 1" error message. matt, I apologize for seeming to ignore your private e-mail. My mails to you and the group were near simultaneous, and I read all your answers at the same time. I'm very grateful for all the work and thought you've put in on our behalf and am sorry for wasting your time by forcing you to read messages twice, Sam Free Print Shop Website: http://freeprintshop.org -----Original Message----- From: owner-freebsd-questions@FreeBSD.ORG [mailto:owner-freebsd-questions@FreeBSD.ORG]On Behalf Of Matthew Jacob Sent: Tuesday, August 22, 2000 9:29 PM To: Sam Cc: freebsd-scsi@FreeBSD.ORG; freebsd-questions@FreeBSD.ORG Subject: Re: Tape problems. As I said to you in private mail, which you seem to not read, I don't believe that early warning is occurring. I asked you whether or not the workaround of specifying a tape length (that I told you) is working for you. -matt On Tue, 22 Aug 2000, Sam wrote: > Right now we are using a Tekram DC-315U SCSI Adapter with an HP SureStore > 24I tape drive.
