Floppy stepping problem

Hi Here is a typical read cycle for getting a track from the M20 disk: FOR sector 1 to 11 setup DMA write clock rate to 3F7h ( may be FM or MFM ) BEGIN set drive motor timeout to nice long number for DOS so it doesn't turn the motor off while I'm using it. If the motor isn't already on, turn it on and add a little delay time to get it up to speed. Do a SEEK to the track ( I do this every time even if I'm already on that track ) Clear Interrupt status bit in DOS Write all the stuff to the controller to read a sector ( including if it is FM or MFM ) Wait until there is an interrupt 6 and then read all the returned status WHILE the status fails if second try, do a READID if third try, do a RECAL if more tries then Error out REPEAT NEXT Sector Use DOS call to write track to a file and repeat it all for the next track. I can break down things like SEEK, READID and RECAL if you think they are needed. The actual code is a little messy since it has been a growing project. I don't seem to have any issues with the clock rate since it has problems during the MFM time and not the FM time. If it had clock problems I'd suspect it would show while switching between FM and MFM. I used to reset the step rate after each DOS call but I'm using the INT 1E and INT 13 AH=0 method and the step rates for the 360K and the 1.44M seem to be OK now. It is just that the 360K seems to get lost after the 1.44M steps tracks. The ReadID on the 360K doesn't seem to help. Dwight
