There is really no need to do that, the process of marking bad clusters is
fairly simple. It is even not nessecary to 'cut' the entire file if only the
middle cluster of it is erroneous. I can write a program which does in a
moment. I just need to know how to access the drive on sector-level without
getting the A/R/I message.
It's disassemble, by the way.

If I recall correctly there is a DiskROM routine to read a drive's sectors.
It returns an error code (if any), which tells you what error has occurred.
But it won't show the annoying (A)bort, (R)etry, (I)gnore message, which I
want to avoid.
The question is: is this routine (which one exactly? and how to call it?)
compatible with all DiskROMs??? (as you can see I don't really trust my
docs, which are mainly from the Dos1 age).
Jon, could you give me an answer???
