I've recently acquired a very clean A4000D that has been recapped and it runs great. It's also in great cosmetic condition.
However, the internal floppy drive does not read any disks. The motor spins, the head sounds like its trying to read, but it gives up after 4-5 seconds. I am thinking misaligned heads perhaps? Is there a how-to or a troubleshooting guide somewhere I could try? I know I could replace it with a modified PC floppy drive but would love to keep the original drive.
