/dev/sr0 not there; optical drive is fine.

Hi,

i recently detected that my optical drive isnt working. I dont know since when this occurs, i havent used it for some days.

dmesg | grep sr gave the following

[   28.430936] sr0: scsi3-mmc drive: 24x/24x writer dvd-ram cd/rw xa/form2 cdda tray
[   28.431517] sr 1:0:0:0: Attached scsi CD-ROM sr0
[   48.399098] sr 1:0:0:0: CDB: 
[   59.331555] sr0: CDROM (ioctl) error, command: cdb[0]=0x51 51 00 00 00 00 00 00 00 02 00
[   59.331568] sr: Sense Key : 0xb [current] [descriptor]
[   59.331572] sr: ASC=0x0 ASCQ=0x0

the kernel seems to recognize the drive correctly

but when i insert a cd or dvd, this happens:
