Scribblings from the Mitchy Side

Techie types - is there an easy way of getting at what's in a PC's cd-rom drive when the bloody thing refuses to open? I've lost a DVD disc and I'm wondering if it got stuck in the old, dead PC. I've taken the side casing off but got foiled at that point because I don't possess a screwdriver of the right size to assist me in dismantling everything else :P It occurred to me that before I start entertaining ideas of mallets and chisels, I should prolly ask here first :)
