I recently had my Mac upgraded to a Plus, but evidently, the bozos who did the job either did the installation poorly, or gave me a drive with a bum eject mechanism. The problem is this: with most disks, if I try to eject, the drive sounds like it's making a lot of effort to get it out, and the disk sort of slowly oozes out of the unit. With some disks, ejecting results in the disk getting caught halfway out. The only way to get it out is to fiddle with a paper clip and pull the protruding part of the disk at the same time. I am almost inclined to suspect that the drive is simply not properly aligned in the housing. It seems like the disk is really getting caught on something on the way out. I was also informed that there is a variable speed control for the drive eject. Another thought is that this is simply set at too low a level. I'd really appreciate any advice anyone has concerning this. I'm reluctant to take it back to where I had the installation done for fear that they'll: 1) charge me an arm and a leg; and 2) discover that they charged me too little for the original installation. I guess you get what you pay for... sigh. --Luyen Chou The Core Corps Harvard University

In Apple's first major computer, the Apple 2, the speaker was under software control, but only by a single bit. The programmer could write a one to it to turn the speaker full on, a zero to turn it full off. The programmer could make sound by modulating the writing of ones to the speaker. The modern Apple product, the Mac, has an 8 bit D-A converter connected to the speaker, allowing for many more possibilities in the machine's sound. Similarly, the original Mac had a one bit disk ejector. Now we are told that more modern machines have a variable ejector control. Think of the possibilities!

This was a common problem when the new 800k drives were installed as the opening is not very big. I suspect that the disk is hitting the edge of the plastic shell when it is coming out and that the disk is dragging. This can cause problems. Keep in mind that if damage is done to the drive then you will be up defecation tributary without a wooden spade-like propulsion unit. Apple dealers do not repair the drives but swap you for another. It is about $115 plus labor. They send the drives to Apple. Apple does not deal with them but sends them back to Sony. If your Mac Plus is still under warranty (90 days?) I would recommend taking it back to the dealer. -- Bill Petro ({ucbvax!sun,altos86,styx}!elxsi!billp) These are not opinions, this is objective truth!

I've received lots of responses from pele about my disk ejecting problems. Evidently this is a common problem with the new 800K drives... especially with upgraded Macs.

If anyone knows a way that the problem can be permanently solved, PLEASE post to the Net... it's really an amazing nuisance to have to keep a paper clip in one's hand at all times. Also, re: disk speed hardware control: I was told by a friend that he visited a repair shop where the repairmen had turned the eject speed up all the way. When they ejected a disk, they simply held their hands out about a foot away from the drive and caught the disk as it came flying out of the slot.

If it were done by an Apple Dealer it should be warranted for 90 days. Take it back and see if they can't do something to get it aligned. Dan Wilson

You're problem sounds to me like it is indeed a housing alignment problem. I've installed a few upgrades myself and you have to fiddle with the drive until it sits just right in relation to the Mac's cover -- otherwise you get the problems that you are having or worse (the disks won't eject at all, and pop themselves back in). It's not too hard to do this yourself if you have some technical experience. (You'll need a long torx #10 driver and a #0 phillips). If not, take it back to the people that installed the upgrade. -- Robert N.

I'm not sure our problems are completely the same, but we had a problem with a mac that was similar. The disk would eject just fine (i.e., proper speed, sound, etc.); it would just get stuck half way out. We opened the mac, took out the disk drive and looked at it for an hour or so. It turned out that one of the pins that holds the disk in place was a little bent. For us, it was the one on the left side when looking front to back. If you look at a disk, you'll see a half-circle on the left and right sides of the disk near the shutter. Those are the places where the pin in question grabs on. We just bent the pin out a little bit and it started ejecting fine. You DO NOT have to disassemble the drive; you just have to remove it's supporting bracket. If anybody can't figure it out, and wants a more thorough description, let me know. Brian H.

I think I'll take mine back and have it looked at. BTW, I've received all sorts of warnings about trying to force the disk out of the drive. If anyone is having the same problem as I am, DON'T PULL on the disk. Get out a paper-clip and ease the disk out. I'll let y'all know if it gets fixed OK.... --Luyen Chou
