Help burning CDs? (lemmy.dbzer0.com)

submitted 2 months ago by [email protected] to c/[email protected]

46 comments fedilink hide all child comments

I'm having an issue trying to burn a music CD for use in my (very old, I know I know) car. I'm running FedoraKDE (40) and Brasero, a Liteon brand external optical DVDRW drive, CD-R (TDK brand), and a Framework 16.

The issue I'm having seems to be that the blank disks(maybe?) aren't recognized automatically by Fedora, when I pop a full commercially released CD in it'll play/rip, but with a blank disk nothing happens, and I don't know where to "save" the "image" of this album I'm creating in Brasero to get it on the disk.

Someone on a random linux forum told some other guy to run cdrecord -checkdrive which says my drive is at /dev/sr0 with a blank disk, but that's as far as I've gotten. Do I choose sr0 as the place to save it? It says "something something overwrite" when I try which makes me wary, it seems it wants to overwrite "sr0" itself and either bork my drive or install, but maybe?

I'm positive it's just something simple I'm missing, any help would be greatly appreciated and I can answer questions and run commands if needed (but I don't actually have WIFI rn, so I'll have to have the package for said command already.)

Thanks in advance.

AH! Oh well no harm no foul, I can run my script as root, I trust me!

Cdrecord -checkdrive does output a whole mess of stuff:

Device was not specified. Trying to find an appropriate drive...
Detected CD-R drive: /dev/sr0
Device type    : Removable CD-ROM
Version        : 0
Response Format: 2
Capabilities   : 
Vendor_info    : 'Slimtype'
Identification : 'eNAU108   8     '
Revision       : 'XL0A'
Device seems to be: Generic mmc2 DVD-R/DVD-RW.
Using generic SCSI-3/mmc   CD-R/CD-RW driver (mmc_cdr).
Driver flags   : MMC-3 SWABAUDIO BURNFREE FORCESPEED 
Supported modes: TAO PACKET SAO SAO/R96P SAO/R96R RAW/R16 RAW/R96P RAW/R96R

And the only part I need is the part that says /dev/sr0/.

I will try deleting the /dev/ part entirely though and see what happens (probably tomorrow evening). If it works that'll be perfect. Thanks!

Edit: No dice, dev=/dev/sr0 is needed in my case.

This is a very goofy workaround for you that doesn't actually check what the device is. Only checks if /dev/sr0 exists and if yes, use that if no then use /dev/sr1. Better solution below this block. But leaving it because I kind of like it's jankiness.

if [ -e /dev/sr0]; then
    DEVICE="/dev/sr0"
else
    DEVICE="/dev/sr1"
fi

Not elegant and a little janky but works.

This will work better. We are taking the output of -checkdrive, searching for "Detected" and sending that to awk. We are telling awk to split that line into columns based on this character ":" and to print the second column. That should give you an output of " /dev/sr0" with a space in front.

DEVICE=$(cdrecord -checkdrive | grep Detected | awk -F ":" '{print $2}')

That should work. But if you absolutely must kill the whitespace for some reason we can add trim to the end like so

DEVICE=$(cdrecord -checkdrive | grep Detected | awk -F ":" '{print $2}' | tr -d ' ')

There might be a more elegant solution by using the output of "cdrecord -scanbus" instead. No clue though since I don't have the hardware to verify from here. Hope that helps!

This looks like it'll work perfectly, thank you! When I get home from work I'll play around with -scanbus and see if it works out first, then I'll try with the space and if no dice I'll try without the space!

I'm also going to try k3b and see how that works as another poster was saying, but at this point I think I prefer the script lmao!
