I constantly come across older CR-ROM drives with sticking trays. I have to stick a pin into the access hole to get them to open. Is there a solution to this problem or is this simply the nature of older drives?

Might be environmental. Heat,cold dry or dusty or even ozone could cause the lube to become hardened.

I've worked with alot of those trying to figure out why they do that. I noticed that when I removed the top cover of the cdrom the tray would open and close with no problem. Put the cover back on and the problem would return.

The covers have an indention above the drive spindle that hold a loose plastic piece that surrounds a piece of metal (I believe it's generically called a 'clamp' or 'clamper'). The center spindle ol the cdrom is magnetic. When the tray is closed the clamper magnetically locks onto the spindle to hold the cd in place.

When you press the button to open the tray the first thing that happens is that magnetic hold must be broken. If the motor or belt is weak that magnetic bond can't be broken and the tray doesn't open.

Anyway, that's my best guess after going through a dozen or so of them.

The rubber belt stretches out too. Probably slips after that.

Could be they are fragile and people slam them closed.

Thanx - I'll take one of the really sticky one's apart and see if there's some obvious flaw!

My experience has been exactly the same as Dave's. Cementing a fiber washer on top of the clamper worked to allow the tray to open but caused other problems; like not reading the disk.

I toss 'em now...
