I can't burn cd-r disks or read cd-r disks with data on them. When I try to burn a Cd-r I get an error log in Brasero. When I put a cd-r disk with data on it in the drive no folder or disk icon appears and palimpsest reads it as a blank disk and "unrecognised".

Cd-rw work fine as do all other disks.

Does anyone know what the problem is with cd-r disks?

Thanks!
