Please bear with me as I'm trying to learn Arch on my own as best as I could.
I just bought a new external DVD+RW, but I need help configuring it.
My Qs is:
I know in Linux, you have sda1, sda2, and so on, plus with Arch system, cdrom1, cdrom2, cdrom 3...so on.
1. However, is there a limit as to how many allowed?
2. In my case, how do I check it? I tried /dev/sda...and keep pressing TAB, but I couldn't find it.
Strangely, I used this for my /etc/fstab
# # /etc/fstab: static file system information # # <file system> <dir> <type> <options> <dump> <pass> none /dev/pts devpts defaults 0 0 none /dev/shm tmpfs defaults 0 0 tmpfs /tmp tmpfs defaults 0 0 usbfs /proc/bus/usb usbfs defaults 0 0 /dev/cdroms/cdrom1 /mnt/cd iso9660 ro,user,noauto,unhide 0 0 /dev/cdroms/cdrom0 /mnt/dvd iso9660 ro,user,noauto,unhide 0 0 /dev/cdroms/cdrom2 /mnt/dvdrw iso9660 rw,user,noauto,unhide 0 0 /dev/floppy/0 /mnt/fl vfat user,noauto 0 0 /dev/sda1 /mnt/usbdrive vfat rw,user,umask=022 0 0 #/dev/sda2 /mnt/dvdrw iso9660 ro,user,noauto,unhide 0 0 /dev/discs/dics0/part1 /mnt/win_c ntfs ro,user,noauto 0 0 /dev/discs/disc0/part3 swap swap defaults 0 0 /dev/discs/disc0/part5 / reiserfs defaults 0 0 /dev/discs/disc0/part2 /boot reiserfs defaults 0 0 /dev/discs/disc0/part6 /home reiserfs defaults 0 0
Initially, I used /dev/sda2 (thinking it's an USB module hardware), but didn't work, until I added another entry /dev/cdroms/cdrom2, and I was able to test with any CDs.
I am nonetheless still confused as to why it was able to read CDs.
The next Qs is
3. Is the parameter "RW" fine with it? I know it's dumb, but since it's DVD+RW, i figure you should put RW instead of RO.
I proceed with K3B to configure the writing device, and K3b couldn't even recognize my internal CD+R (/dev/cdroms/cdrom1), let alone my external DVD+RW.
I tried to add both manually, but always get the error that both devices doesn't exist. Please help.......
For the info, the K3b version is 0.12.2, and keep crashing when you close it.
Sorry for the long thread, and I appreciate any helps to get both my devices detectable in K3B
I managed to get K3b recognizes my CDR, DVD, and DVD+RW by simply adding the user to "OPTICAL" group. Silly me!
However, if someone can answer my 3 questions there, I'd appreciate it.
1. There might be a limit set in the kernel. I guess that if there's a limit, it's probably a large number. I'm not an expert t on that, though.
2. My external cd-RW/DVD drive is listed as /dev/sr0, if I remember correctly.
could i take a look at your fstab entry if you don't mind?
I just made these changes because I realized I didn't configured my new system to use my external CD-RW/DVD drive.
Here's my entry in fstab:
/dev/hdc /mnt/cdrom iso9660 ro,user,noauto,unhide 0 0 /dev/hdc /mnt/dvd udf ro,user,noauto,unhide 0 0 /dev/scd0 /mnt/cdrom_ext iso9660 ro,user,noauto,unhide 0 0 /dev/scd0 /mnt/dvd_ext udf ro,user,noauto,unhide 0 0
/dev/hdc is my internal CD-RW/DVD-RW drive and my external CD-RW/DVD drive is now /dev/scd0 (not sr0 as on my last system). I also use the ro option as the rw option gives me an error:
mount: block device /dev/scd0 is write-protected, mounting read-only
It shouldn't affect burning since you don't mount the cd/dvd to burn it (I've read that on these forums). If you restart udev:
/etc/start_udev mount /dev/pts mount /dev/shm
it will create symlinks to the external cd/dvd drive.
if i rem right, i needed to set rw to write to the cd/dvd writer.
extract from fstab :
/dev/cdroms/cdrom0 /mnt/dvd udf rw,user,noauto,unhide 0 0
thats not to dispute the previous comments tho, just to mention what works for me.
I haven't tried to burn a cd/dvd yet. It's possible that you need rw. I have it on my old fstab for the cdwriter.
