Re: 5.25 floppies image profile
A preservation stream is always preferred, as there are some information in it which are not stored in the standard mfm image. Just for example: The order of the sectors on side 2 in your stream is very unique! It doesn't start with sector 0 (next to the index signal) but with sector 4 instead, havi...

Re: 5.25 floppies image profile
Aahrg! Yes it looks as if HxC is bad in this case and the floppy is fine! Never saw this behavior before So now we know that it's standard mfm encoding, 400k in size, organized double-sided with 40 cylinders, 10 sectors, 512 byte. And its not MS-DOS, CPM or UNIX (according to whats written on it). S...

Could also be the track zero sensor not being recognized! I would check for dust on the sensor first. If that doesn't solve it, I would try a different cable...
I agree with ZrX in that the printing on the screen would be much more helpful than the video in this case!

Re: 5.25 floppies image profile
Yes, it would be nice to see a dump with some data on it and not just an empty disk. It would also be interesting to see if the last tracks are unformatted per design (on each floppy) or or only an error on that particular floppy. The drive seems to be fine. There are no errors in the dump (at least...

Re: 5.25 floppies image profile
This decodes fine to mfm sector image with 40 tracks, 10 sectors , 512 byte. But the last 6 tracks on side 2 are missing or not formatted! And the floppy looks as beeing almost empty (not just formatted but filled with hex 6D). I don't have any clue about the filesystem at all!

Re: 5.25 floppies image profile
Nobody can tell that if you don't provide some information about the computer system they are made with! Just being 5.25 inch in size it could be everything from the profiles list...

Re: Question about a copy protection, Contra Copy
There are 32 overlapping sectors on track 1 side 0. Easy to write with a sector orientated controller but impossible to read with all it contents. So yes you can't copy that with any WD controller. But it should be no problem for a track orientated controller like kryoflux. Tested it on a WinXP Lapt...
