im trying to get my cdrw to record. it is already set up so that i can use it for reading cd's but i cannot get it to burn anything. in the past when i used redhat the drive burned stuff, not with slack. what settings do i need to modify the drive so that it records and rewrites for that matter. -buslogic 12x10x32

Is there a scsi chain detection in the output of dmesg?

Long ago when cdrecord first came about, they decided that in order to avoid vendor specific hoo-hoo with every possible drive to just have them emulate being scsi devices. This requires a kernel parameter to be entered at boot ("something quick and dirty you can stick in /etc/lilo.conf"), and then re-run lilo, usually:

append="hdd=ide-scsi" (depending of drive, hdd, hdc, hda, yadya)

RH does this for you automagically. Slackware now at least asks you during the config, after package installation, but leaves it up to you to do.

thanks finegan it worked, i can burn, but now i cannot mount the drive. the burned cd workes in windows.

also, when i did dmesg the post said that i had a 40x dvdrom drive, and windows says it's 12x, dont know the real speed got it from a friend used. what's going on here.

Probably linux states CD read speed, and windows DVD read speed, mine Samsung is reported as 48X DVD-ROM drive but I believe this is CD read speed, as for your mount question, you need to adjust a mountable device it is no longer hdX it is scdN, run cdrecord -scanbus to figure out what scsi channel it is on and adjust any symlinks you made + /etc/fstab if you don't want to type everytime
mount /dev/scdN -t iso9660 /mnt/point
Substitute X and N for a real letter and number that reflect yoiur system setup.

Neo, you get /dev/scdX on emulation? I always end up with /dev/srX, am I missing the difference between the raw device and something else?

Finegan, I have been noticing this alot lately. I on the other hand always end up with scdX. Any light on this would be greatly appreciated. Thanks!

Long night at the pharmacy? I just swapped out my server... gahh there's a lot to remember, especially when you've hand hacked the config scripts to pluto and back.

I just mounted my REAL scsi cdrom and the fake atapi emulated one using /dev/scd0 and /dev/sr0, and neither are symlinks to the other. Wiggidy.

Now here's the weird thing, they seem to have the same perms, yet I've never been able to get grip to work with a link to /dev/sr0 except as root and now it seems to be happy with /dev/scd0, but that may simply just be a grip bug.

Weird,

Finegan

I've never had /dev/srN it always has been /dev/scdN for me, but what I've noticed when I had a working CD-R/RW (still have none, lack of extra $$$) for some reason eroaster thought that my cd-r/rw was /dev/sg0 I have a SCSI scanner (UMAX Astra 1220S + Adaptec SCSI card AHA-something, don't rememer its name got it from ebay for $6.95) and it is /dev/sg6 I believe I am not infront of my box, but I am pretty sure it is /dev/sg6. BTW eroaster worked OK with /dev/sg0 settings if I only ran it as root, even though all that suid goop was taken care of along with the perms, yada, yada, yada. Other cd-r/rw software accepted only /dev/scd0. Unfortunately, I have zero to nothing knowledge about SCSI ins and outs, I hope someday I will know a little more other than how to pronounce SCSI (skah-zee).
