I have been having trouble recognizing blank CDR CDs. I was trying to burn an ISO using K3B but I am told that there is no media in the drive. The drive works and has burned many things before; that is not the problem. If I put in an audio CD, I get the system menu (KDE auto discovery, I think) that asks what I wish to do, and it can be played fine.
For some reason the CDR disks I am using seem not to be recognized by the system. I have tried about five for them from a stack of 100 disks. None of them are recognized. These are CD-R's from SONY and I am wondering whether I have a bunch of dud CDRs on my hand, and whether there is an easy way to check this.
Assuming for a moment that these disks are fine, is there some set of commands that can force the harddrive to look for media that it cannot detect (sound sort of paradoxical, I know). Also, has anyone else had problem with SONY branded CDRs on linux machines - could there be some initial code that is not recognized, for example?
don't know if there is a hardware or software solution but I would appreciate any advice (seems like a waste to toss a stack of CDs).
