Unable to read 5.25 ADFS E discs #34

Closed FrankHovis closed 9 months ago

FrankHovis commented 10 months ago

I have a number of 5.25 ADFS L format discs, non of which I can read. Ive successfully read 3.5 ADFS, 5.25 DFS and PC format discs, so I'm reasonably sure the hardware is ok. ADFS L discs just don't get recognized:

Is ADFS-L Assuming 300 rpm? Can I force a format to be used?

picosonic commented 10 months ago

Can you capture disk to a .RFI file and send to me to have a look at please?

The RPM mismatch could well have an effect, as it is taken into account when calculating bit cell window size.

drivetest will count index pulses on track zero to determine RPM, the capture program should do the same on a per track basis, but looking at the code it only does this when writing to .SCP and .RFI files.

300 RPM is the default unless a different RPM is detected.

You could try capturing to RFI file and then use that capture file as input when converting to an ADFS disk format. That way the RPM would be captured correctly.

Let me know if this works and I can update the code.

ADFS L format.zip

I've tried various attempts with different discs all in ADFS-L format, using various different options of sides/sectors etc. I just can't seem to get anything to work. I'm starting to wonder if I have some hardware issue as:

Single-sided disk assumed, only found data on side 0

doesn't seem at all right, some of these discs should be full.

I have two drives, both Canon MD5501. I can read both sides of a BBC DFS disc, but it'd be just my luck for them to both be faulty.

picosonic commented 10 months ago

I've managed to get a catalogue from that image by manually overriding the bitcell window size down to 3.33us (from 4us).

I also got sector data out of the file by converting the RFI to SCP and loading it into HxCFloppyEmulator, then dumping to generic IMG format, so that may be something you could try.

I've made a number of changes for this.

Firstly you can force an RPM value on the command line, this is incase the RPM was calculated wrong or the index sensor on the drive isn't working correctly.

Next I've fixed the bitcell window adjustments based on the RPM variance from target RPM.

Lastly I've changed the DFS detection algorithm to only validate against disks encoded in FM format, this is because the RFI you posted was validating as DFS even through it was ADFS.

I'll close this issue for now as it's working for me with your RFI image. Any further issue please raise a new issue on here.

Thanks
