All standard tracks 0-79 read in successfully. For track 80 a "<mismatch>, *N" was reported and tracks 81-83 where unformatted.
I was interested in what kind of data is stored in track 80 so I tried to read the content e.g. with an hex editor. The problem was that the tracks 80-83 were not stored in the "disk.img" (maybe because of automatic image sizing) so no data was there to inspect. The parameter -os -oe (output image start/end track) did not solve the problem. Also the stream files cannot be used directly to search for an disk content.
Is there an easy way (except with programming) to access the content e.g. from track 80 as if it had been read by an standard floppy disk controller even if the track is invalid or contains garbage?
