My Powerbook stopped recognizing all forms of optical media. It recognizes the drive sort of, but I get an error, "The disk you inserted was not readable by this computer," but with all disks. I did nothing to the firmware, no recent software changes.

It also shows up really weird in the system profiler:
M@TRHHT@ DVD,R UJ-844E:

Firmware Revision: DLP2
Interconnect: ATAPI
Burn Support: Yes (Unsupported)
Profile Path: None
Cache: 2048 KB
Reads DVD: Yes
CD-Write: -R, -RW
DVD-Write: -R, -RW, +RW
Burn Underrun Protection CD: Yes
Burn Underrun Protection DVD: Yes
Write Strategies: CD-TAO, CD-SAO, DVD-DAO
Media: No

Any suggestions?

Also, Reset PRAM, PMU with no luck.

Can you boot from it? If you can, it could be a corrupt driver -> archive & install your OS.
If not, the drive is probably fried.

i had the exact same problem just one month ago in my powerbook 15". i had the same matsushita drive i think and i used it a lot to burn dvds. towards the end it started getting really loud then one day it gave me that error and i'm not one to go looking for answers online (i know it would probably be easier), so I went to the apple store and told them to replace it... the guy there said the optical drive had just been used too much and replaced it... bill came to 718 dollars. thank GOD i have apple care haha.
