Dear CP/M User:
Last summer before our school started, I ported a file to MS-DOS diskette
with my commodore 128 w/rfc512 disk drive using Trans-128 software. I
formatted MS-DOS diskette on my commodore 128 and put a file into it.
I returned back to school, I tried to dir my MSDOS disk on school's
IBM PC. It worked fine. I tried to copy a file from commodore 128 to
hard disk but it said me that sector not ready error. I tried another
file to my MSDOS disk but copy slowed down much. What happened?
I believed that trans-128 misplaced sector#/track# on all tracks that
made MS-DOS system slowed down. Why?

My guess, not having Commodore equipment is that the PC disks you formatted on the Commodore had a built in skew factor. That is is, that the order of the physical sectors was not the order of the logical sectors. Many cp/m systems did this for dd rather than use a software sectoring skew as on the 8" sd format. However, on a standard PC disk, the order of the physical sectors is 1,2,3,4,5,6,7,8 9 whereas on your
