I'd like to ask the net for help with an internal 800K floppy drive on a Mac SE. Whenever I put a disk in the computer it displays the "initialize floppy?" dialog box. At first I thought I had a bad disk ... then I tried inserting several other recently used "presumed good" disks and they all give the same "initialize?" dialog box. I tried putting in a new disk and telling it to go ahead and initialize. It tries for a second, then says "initialization failed!". I doubt that all the floppies could suddenly go bad all at once, since they're stored in several different locations around the room. This is my sister's computer; she uses it to work at home. My four year old nephew, unfortunately, seems to have taken a liking to the Mac, and has learned how to turn it on. My suspicion is that he may may tried to insert a floppy into the drive the wrong way, forced it, and damaged the insides. My sister says she's noticed the drive making "funny noises" recently :-(. Is this idea consistent with the symptoms mentioned above? I've brought in my own "presumed good" disks and gotten the same results. What else could cause these problems? Does she need to replace the drive, or is there a simpler fix? By the way, it's a Mac SE, about two years old, running System 6.0.5. Please respond by e-mail to the address below. Thanks!!!

I had a similar problem recently - first the internal drive started misbehaving, and then the external. When I opened the Mac, I found that the 5 volt rail was down to ~4.4 v. Despite this low voltage, the main board kept on working happily! The problem was the power supply connector on the analog board. It had overheated at some time, and this had damaget the plating on the connector, causing a high resistance connection. I replaced the connector, recalibrated the power supply, and everything, including both floppy drives, worked perfectly.
