Drive reads no discs

Hello, and thanks for taking the time to at least see what problem I'm having.

First off, the problem: discs will not mount. None - this is not a problem specific to CD-Rs, DVD-R/RW.. no disc will mount, they just eject after the drive attempts to spin up 2 times (from what I can hear, just guessing here).

Next, what I was doing when the problem first started happening: installing windows games to run them with WINE (darwine speficially).

What I've done so far trying to fix the problem: after reading lots of the articles on this forum, I've tried to...

1) repair permissions (I don't know why it would help an error with the disc drive, but oh well, I tried it and it didn't fix my problem)
2) find the preference list for WINE and delete them. I thought maybe when I was setting up the drive (IE choosing what media is C:, D:, etc) I somehow screwed up OS X's ability to read discs.


Other info that might be useful -

-when trying to get a disc to read, no messages show up in the Console

-my drive: MATSHITA DVD-R UJ-857E with firmware ZA0E



hope that gives you all enough information to help me out here.

Thank you in advance
