Thanks to Bruce, Phil, and Des I now understand the floppy problem. Here is the scoop. > you should not use format unit (0x04) just to initialize the floppy >drive. This will instead try to format the floppy diskette ! >Des. I used the format because I believed (incorrectly) that the monitor "raw" command was broken and I needed to get a floopy formatted. It turns out that formatting takes too long and the Minix scsi driver gives a watchdog timeout. Once I took the format command out of my initialization sequence I was back to the single 5/24 error that I also get from my hard drives. In other words I have a working floppy drive. The next step is to dig a hole through the ioctl mess in the kernel in order to get other scsi commands to the drive. I suspect that the watchdog timeout problem will continue to be a problem too. Is there a solution to the latter besides increasing the timeout length. (Formatting hard drives can take tens of minutes). Sverre
