Not the first time I have heard about this with Toshiba drives. I have a Toshiba CD-ROM drive, 32X, whose tray won't open anymore. Occasionally, when the Earth is perfectly aligned with Polaris (the North Star), the tray will open. But how often does that happen?
I don't know about the blue lever you are asking about, but I would recommend finding a replacement for the drive or getting it repaired. At the current cost of DVD-ROM drives, though, a replacement would most likely be cheaper.
No, I like women.
