Troubleshooting and FAQ
Questions
Can Disc Writer make audio CDs?

Can I burn a bootable Linux installer?
Yes. Use Burn a disc image with the .iso file. Do not add the .iso to a data disc as a file.
Can I add files to a disc I burned earlier?
Yes, if the disc was not closed. See multi-session.
Can I erase a CD-R or DVD-R?
No. Write-once discs cannot be erased. Only CD-RW, DVD±RW, DVD-RAM and BD-RE can.
Can I try the app without a drive?
Yes. Choose Use an image file as a drive… from the More menu on the drive card.
Problems
"No optical drive found"
Plug in the drive and choose More › Rescan drives.
"Drive not accessible" or "The drive could not be opened — see Disc info"
Your user cannot open the drive. Add yourself to the cdrom group, then log out and back in:
sudo usermod -aG cdrom $USERIf Disc Writer is installed as a snap, also run:
sudo snap connect discwriter:optical-drive"Install xorriso to burn discs"
The burning engine is missing. Install it and restart Disc Writer:
sudo apt install xorriso"Too much data for this disc"
Remove items until the gauge no longer shows Too big, or use a larger disc.
"The disc is full or closed"
Use a new disc. A rewritable disc can be erased, or burned with Erase the disc first turned on.
The burn fails or verification fails
Select Show details to see the reason. Try a new disc and a lower Write speed. Run a simulation first to check the drive without using up a disc.
I stopped a burn and the disc no longer works
Stopping while the drive is writing usually leaves a write-once disc unusable. A rewritable disc can be erased and used again.
