Specs: Microsoft Windows XP Professional, 2.793 GHz / 503 MB
I have 2 cd drives that I want to try and fix.

1.-the first one has a screw or something loose and rattles like mad.

2.- the second one ,will not eject when either pressed on the eject button or clicking eject in xp.
-------------------------------------
the 1st drive I have dissasembled but cannot get into the plastic casing, the rattling remains inside this plastic casing , any one know how to open this ,would be greatly appreciated.

the 2nd drive I have not dissasembled yet and think there maybe a cd inside it jamming it closed, any ideas would be greatly appreciated.

Also I was wondering what the small hole is for underneath the tray?

Small hole is for a paper clip or similar tool that will fit in the hole to push the device open so you can remove the stuck CD.

Generally they're not fixable.

As mentioned above, use the paperclip, if necesary to pop the tray open. (It's easier to disassemble if the tray is out). Remove the front plastic bezel that surrounds the tray. Then turn it over and remove the 4 screws on the bottom that hold the cover and bottom plate together.

The rest you can probably figure out.

Here's someone's idea of disassembly:

Now that's what I call a sticky situation

ok, the second drive I got open with a needle , just to find there was no CD inside, after I pressed the button for it to close , it stayed shut again, so my guess is this one I can chuck away.

Tommorow I will try the 1st drive to see if it will work regardless of the rattle inside.

Take it from a guy who's tried to fix a crap load of optical drives.

Step 1. Chuck 'em and buy new ones.
Step 2. Uhh, sorry; there is no step 2.

Take hammer out of tool box. Put on gloves and safety glasses and whack them things until they either work correctly or are smashed to pieces. I can say it has never fixed it for me but I always feel better about buying a new one.

"ok, the second drive I got open with a needle , just to find there was no CD inside, after I pressed the button for it to close , it stayed shut again,..."

If the led on the front of the drive does not light up when you press the button for ejecting or retracting the CD while the computer is running, the drive's board is fried.

If this is a desktop drive, if you open the tray by pushing in a needle or wire, there is usually a small rubber belt, usually it's black, that is supposed to run between two small pulleys, that you can find near the front of the drive below the tray by looking through the holes in the tray, when there is no disk on the tray. That belt must be there and be adequate, otherwise the tray mechanism cannot retract and eject. Sometimes that belt has fatigued such that it it slips on the pulleys, or the belt has broken. You can use an elastic band of the right size and tension to replace that belt, then the tray will often then open and close fine (e.g. get yourself a bag of assorted sizes of elastic bands from a "dollar" store).
To find out whether you should bother doing that, with the data cable connected to the drive, insert a disk that the drive can read into the tray, close the tray, and see if Windows recognizes the disk. If it does, try replacing the belt.
