C.K. Sample

For some reason the combo-drive on the 12-inch is no longer reading CDs. Ejects them after thinking really hard for about 15 seconds. Strange thing is this: all varieties of DVDs, CD-R, and CD-RW seem to work without a hitch, although I am having trouble burning. It is just regular CDs that are giving me the trouble. I did check out the Apple Support page and zapped my PRAM several times, as well as resetting the PMU, all to no avail. Turds! Any ideas?
UPDATE: My friend, Jason, thinks that it might be another infamous 10.2.8 bug, as his iBook’s CD tray refuses to even open since the update. So, I am going to try rolling back to 10.2.6 and see if that fixes the problem. Wish me luck… New UPDATE: Well, it won’t let me reinstall the 10.2.6 combo over 10.2.8, and although it will allow me to restart from the DVD recover disk that came with my PB, it will not let me reinstall the OS. Gives me a very odd error each time I try. I called Apple Support, and they are sending me a box to send my 12-inch to them for them to rework it. I wonder if there is anyway I could “trade-up” to the newer model. Maybe if I wrote a very long sob-story letter about how my first 12-inch wobbled, and this one suddenly starts not mounting CDs after a couple of weeks with only an hour and a half of battery…
