Message-ID: <20020514152334.A9170@mars.thuis> Reply-To: Axel Scheepers Mime-Version: 1.0 Content-Type: text/plain; charset=us-ascii Content-Disposition: inline User-Agent: Mutt/1.2.5i Sender: owner-freebsd-questions@FreeBSD.ORG Precedence: bulk List-ID: List-Archive: (Web Archive) List-Help: (List Instructions) List-Subscribe: List-Unsubscribe: X-Loop: FreeBSD.ORG Hi All, I purchased this drive, thinking it might be a nice solution for my backups. I installed the drive as master, with the cdrom as slave as my dmesg output shows: ad0: 14324MB [29104/16/63] at ata0-master UDMA33 ast0: TAPE at ata1-master PIO4 acd0: CDROM at ata1-slave PIO4 So my next guess was: freebsd# export TAPE=/dev/ast0; mt status Mode Density Blocksize bpi Compression Current: 0x01:X3.22-1983 32768 bytes 800 none ---------available modes--------- 0: default variable 0 none 1: default variable 0 none 2: default variable 0 none 3: default variable 0 none --------------------------------- File Number: 0 Record Number: 0 Residual Count 0 freebsd# dump -0ub 32 -d 800 / .. which went fine until it wanted to close the device....It just 'hangs' there and there's no way out of it execpt a reboot :( As I understand it, it's probably because the drive isn't _that_ standard and it uses different ioctl's for the commands. I searched the archives a bit and saw that at least 3 people were able to backup and restore the data using the /dev/nrast0 device, but I don't have such a device. ast0 means rewind when done nast0 doesn't rewind. My guess is that the previous mentioned nrast0 device is a 'raw' device which doesn't rewind. In /dev/MAKEDEV I can't find an entry for nrast. So, what to do next? I really like to use it on FreeBSD but I'm kind of stuck right now. Does anyone now what the status is of the ast driver for supporting this device? I saw that Soren does some hacking in it from time to time, I'm curious about what exactly has to be done, so I can be helpful making this device to work. Can someone enlighten me a bit about this?
