Kubuntu 12.04 no longer recognizes blank media

[JohnArgent]

Suddenly my computer no longer recognizes blank media any disc that something on it is mounted and available, am unsure what to do next any suggestions are greatly appreciated, thanks from a linux noob

[JohnArgent]

Ok thought I better add some info still searching for clues my system was function just fine came back the next day went to burn another data disc and k3b says please insert an empty or appendable dvd or bluray disc , I dont think its hardware because both k3b and dolphin recognized a disc that has something already on it just not blank discs

Two thoughts occur to me:

1) Maybe you have some blank disks that are bad, or just incompatible with your drive.

2) Even though it may read disks, it could still be a hardware problem - the drive's write laser may have failed, or simply be dirty. If the drive is a few years old, this may be the most likely possibility.

Well you Just pegged it, as I sit here writing this K3b is burning a disc the answer was number 1, I opened spindle of dvds and pulled out another one threw it in and it is working , now one question how do I mark this as solved, and thank you HalationEffect, here I was looking for a software problem and it was simply a bad disc

Glad to be of help, and also glad it turned out to be bad disks rather than a hardware failure

Yes but the bad thing is that it seems like the discs are not bad exactly Asus 24b1ts dvd writer does not like abunch of the discs in this spindle of TDK, which has never happenned before, but I take the disc out of my new pc and stick it in my older pc with a memorex dvd writer and no problems (bangs head against wall going AAAAAAGGGGHHHHH)
