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 <ST315311A> [29104/16/63] at ata0-master UDMA33
ast0: TAPE <OnStream DI-30> at ata1-master PIO4
acd0: CDROM <CD-ROM 40X/AKU> 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?
Thanks,
