Thanks David - just tried Awave ... but I need FZF format for Awave and all I've got now is IMG form Kryoflux and HFE from HxCFloppy - is there a way to create FZF from HxCFloppy ?

the only option I found was "Casio FZ-1 IMG2FZF v0.1 - Automatically convert Casio FZ disk images (IMG & HFE) to FZF format " - but that complains my IMGs are corrupt...

thanks for your help...

I've tried two drives so far... - one (from my old esynth (replaced with an emulator)) seems better than the other

If IMG2FZF says that, it will probably be right. The HxC-Tool can also read raw streams from kryoflux preservation dumps. Yes, and IMG2FZF reads HFE files as well as IMG files.

If you get bad images the tools won't make them good I guess. Are the floppies clean or are there visible spots (mold) on the surface? What happens if you set the retry parameter to a higher value (maybe 20)? Do the floppies have the HD notch? If not you have to fake the HD switch (only a few drives switch from DD to HD mode with the -dd parameter, thus ignoring the notch).

Or you may put a sample (raw kryoflux dump) somewhere online and send a link to it here for further examination...

Can you upload one of the bad dumps somewhere to look at?

Thanks @David and @ZrX - I've uploaded three IMG files and the associated logs from Kryoflux to a public folder on my onedrive: https://1drv.ms/u/s!AlfwmVQ2-FH2gRRr-hG ... 7?e=00mhHS

the disks surfaces look ok - but they have been in a case in the garage for nearly 30 years... - other disks work in my Kawai Q80.. but I sold the FZ1 25 years ago so can't try them directly. The disks are mostly (Sony and TDK) HD disks (with the extra notch). I've got some 99.9% alcohol and a disk clean 'kit' from https://www.floppycleaner.co.uk/ on order to make sure...

the logs show the options on Kryoflux I used "-v360 -z3 -i4" though it seems to have automatically added some default options I can see in the log -v360 -z3 -i4 -i0a -d0 -e81 -dd0

thanks very much for all your help !

I calibrated both my drives - one (ex EMU sampler) comes up with 81 tracks and the other (random PC drive) with 83 tracks. the old EMU one seems to find less bad sectors...

With the dump I meant the raw stream files generated from the disk, but from the log it seems you only made a direct to image reads of the disks.

As FZ1Banks1 looks the worst, if you could make the raw stream of that disk using just a blind read with dtc -fname_ -i -l8

The images almost look the same as the one included with IMG2FZF, but there's a small difference before the filedata in your images. Not sure if that's what trips IMG2FZF...

Also BeginVce.img is ok even if it shows errors. The errors happen at the last tracks but the disk space used doesn't reach the bad regions of the disk.

Btw, about the options, -i/-i0/-i0a should come before the .img filename (but after a raw stream filename) as it sets some basic parameters for reading the disk. -d0 doesn't really matter if you have just single drive connected. -exx you don't really need to define unless you need to limit the tracks to certain range. And -dd0 is typically only useful with 5.25" drives.

Thanks @ZrX - I was using the GUI so I've switched to CLI (as GUI seems to add the extra parameters and redone FZ1Banks1 as you suggest and put the RAW stream files into the related folder in my public share. I also did the BeginVce again with -e80 as an extra parameter and included the RAW stream too - still one bad block (again put into the public share)

I notice from http://www.buchty.net/casio/fz1-diskformat.html the disk format is only 80 tracks so thought may help by limiting it . Are there any other settings / parameters I can tweak or use to set up a Casio FZ1 disk format option with the details that are specified in the link?

thanks again for you help - I will retry again once disk cleaner arrives.... - all input / help v much appreciated!

hmm - I had a good look at the best disk and could see a little so cleaned off and got a read with no bad sectors "Fz1BegVceGuicleaned" in share ... but IMG2FZF still complaining 'Corrupt or otherwise not a proper Fz1 disk' ? - how do I see what's on the disk to see?

The last (cleaned) raw streams you uploaded decoded fine without read erros.

But it looks (as ZRX said), that they are different to the IMG provided with the the IMG2FZF tool.

A little google search reveals that FZF seemed to be a full dump. But there are other formats related to the Casio FZ1/FZ10. For example FZB holds a bank dump and FZV a voice dump only! Maybe your floppies are not full dump but bank or voice dump? IMG2FZF tool accepts only full dumps. (AWAVE also imports from FZB and FZV.)

David - thanks - I should have thought of that - so I think I am stuck as there isn't any (existing) way I can find to read an IMG and 'convert' it to an Awave readable FZV or FZB?
- other than finding someone with an FZ1/10/20 load it and save as FZF (full dump) so I can then use IMG2FZF and thence FZF into Awave
- PS I tried the obvious changing file type of the IMG to FZB/FZV but clearly that doesn't work as need to read the file format form the IMG

any thoughts?

From the filenames I'd then say beginvce is a voice-disk as it only contains one 16-bit monosample and fz1banks is a bank-disk having multiple voices. FZF looks like they contain multiple banks of multiple voices.

FZF is simple as the converter only strips few sectors from the beginning of the img-file and the empty space from the end. If I try to save banks or voices from the included img the data looks similar to what's on beginvce and fz1banks, but if I strip sectors from the disk images accordingly they're still not accepted.

Just telling Awave the data is 16bit mono to open the data, and then trying to save as banks or voices modifies the data a little, but it still looks very similar to what's on the disk images.
