Due to the tremendous response (great to have friends!), I solved the problem with my 800k disk drive. Since there were over 15 replies, and basically three suggestions as to what might be wrong, I thought I`d summarise here. Here was the problem: > My recently upgraded Mac 512E is having problems with >the internal drive. Here`s what happens: >intermittently a disk will not eject completely. >Instead it sticks out of the Mac about 1/8 inch, and there is >some mechanism in the drive which won`t allow me to manually >pull the disk out. Apparently this is a very common problem! These 800k drives are overly sensitive to alignment, and their eject mechanisms are not very sturdy. The first suggestion involves disks with too many labels attached or with a label that is not attached completely. Some said that a label or portion of a label came off in the drive and fouled up the eject mechanism. I examined my drive and couldn`t find any labels or portions thereof. The second is that the drive needs to be carefully aligned to the Mac case, or the disk may rub against the opening, and the eject fail: ---------- >It sounds like your new drive was not properly mounted in the Mac's frame. >If the 800K drives are not properly aligned with the frame and the front >bezel, it can cause friction which in turn causes ejection to fail as you >describe.

It's easy enough to try. >Mike Ching Advanced Micro Devices ---------- This is what I did. However, it turned out that the dealer who mounted my new drive only put three screws in, instead of the four required. The crucial missing screw was at the front right, and the disks were indeed rubbing against the front right of the bezel. I am currently attempting to get the dealer to give me another screw... but more on that later... The final suggestion was more exotic, but also seems plausible: ---------- >Whatever you do, DON'T pull on the disk. Follow these steps: >1) Open the case. Torx-15 screwdriver required. Remember, there are >five screws (one in the battery compartment). >Pry the back off slowly and carefully. 2) Pull off the logic board (detach the ribbon cable connecting it to the power supply first). Unscrew the screws which mount the drive and detach the ribbon cable from the logic board. >3) Once the harness is free, go to work on the screws which hold the drive >in the harness. Once the thing is free, look at it's "left" (as seen from >the front) side. You may want to take a spare disk and examine it (look for >the small circular notch on the disk's left underside near the metal door). >The disk in your drive is being held by a small arm which swings into the >little indentation on the side of the disk, and which SHOULD swing out and >allow the disk to move freely after you use the ol' paperclip routine.

Work it in and out until satisfied. >Chris Schmidt/Lincoln-Sudbury High School Sudbury Ma -------- There was even a suggestion to solder a metal reinforcement onto this arm. Luckily I don`t think I need to try this. Finally, many people remarked that my dealer was being unscrupulous in claiming they were going to charge me for warrenty work. Given that the problem was their fault in the beginning (missing screw), I certainly agree. However, before being guilty of possible slander, I`m going to have another discussion with them about their policies. If they persist in the behavior, I`ll certainly post the name! (That`s a threat :-( ). Thanks for the help! Its great to have such a support group. Jim Meiss jdm@uu.warwick.ac.uk (UUCP) until 30 April jdm@ut-ngp.utexas.edu thereafter
