110 Portable Plus software, Teledisk

RE: 110 Portable Plus software, Teledisk
I had no luck.
Teledisk refuses to restore the image back onto a DD disk.
It stops immediately, saying: cannot find cyl. 0 side 0 sector 0.

@ Dave: I should go for a slower machine and/ or another disk controller, since you have been successful.

Strange: The FD2IMD conversion utility from Dave Dunfield's image disk pac doesn't work for 110PROGT, it states:

" TD 1.5 3.5 LD MFM S-Step, 1 sides 7/01/2012 20:38:21
110 PROGRAMMERS TOOL KIT
45419-13001
Cannot do mixed sector size within track. "

Does that explain anything?

@ Paul:
Like you I was able to translate the FD0 image to hpi using FD2HPI, but I'm not sure whether the resulting file is of any use. The translation routine warns: No LIF file!, and it describes the image as follows:
number of cylinders: 71
number of heads: 1
number of sectors 17 (!!)
sector size: 256

According to Dave, FDIO -info says: 16 sectors, obviously a contradiction.

As mentioned before, the hpi plugin for total commander cannot open the hpi file, nor can Winimage open the corresponding .ima file ( which is created before the hpi file, as an intermediate step ).
Even if the hpi file is the "correct" flat binary, I can't imagine that it should be an easy task to extract the files from it without special tools, just by means of a hex editor. You have to have an exact knowledge of the directory structure, f.e.. Since I plan to use not only 110PROGT, but several other disks that I can't currently convert as well ( ECMPORT, f.e. ), binary analysis seems to me the (too) hard way.
Since you and Dave were able to restore the Teledisk image to disk, I have to search for hardware that better fits the requirements, I guess.
