Writing Gotek QL Image Disks
Re: Writing Gotek QL Image Disks
Thanks, but shouldn't it be 1.44Mb in size as a formatted image?, I tried it anyway and it doesn't show as format and still gives a "Format failed" after about 60 seconds.
I may be missing something and the Thor can't support 1.44mb floppies. It does seem to report 1440 sectors though.
Is it possible to get a blank QL formatted file thats 1.44Mb in size. I may just be wrong and the Thor can't support 1.44Mb.......

Re: Writing Gotek QL Image Disks
Did I screw up? The file was created with the -fhd option which should have worked. There are three options, -fdd gives 720Kb, -fhd gives 1.440MB and -fed which is 3.2M. Hang on, checks bash history....
Code: Select all
qltools ./image_1.44.img -fhd "1.44 Image"
Code: Select all
ls -l *.img

1440 sectors? It should be 2880 for a 1.4MB floppy. Hang on, checks with QPC2... dir flp2_ gives:
Code: Select all
1.44 Image QDOS HD
2871/2880 sectors
I think you are correct about the Thor, given the above. I obviously can't confirm as I never had one. Wanted one though.
Cheers,
Norm.

Re: Writing Gotek QL Image Disks
Okay I tried to dig further and tried a few QL emulators to try and generate formatted disk images, finally settled on Qemulator, which when I tried to register for Pro says you can't but gives you a free code for Pro until April, so useful if anyone wants to check it out. Seems to work fine.
So I generated 720k and 1.44k formatted images, when I go to look at them on the Thor they are 1440 and 2880 Sectors, when I format a 720k Disk on the Thor its 720 Sectors.
So does the QL native floppy Disks have a different sector size?.
Curiously if I mount a 720 Sector img on Qemulator it reads it fine, allows me to add files and writes it, which I am then able to load and run on the Thor.
So I'm now more confused and think I'll stick with 720k images.
Will attach a Thor formatted 720k disk image with 712/720 Sectors (please note you need to change the file extension back from zip to img, I don't seem to be allowed to upload ".img"), I'd be interested to know if this works on a normal QL and if it still shows 720 sectors.
Or is all this quirks with the Gotek and I need to change some configs........

Re: Writing Gotek QL Image Disks
The FDI Driver 2, and the Image files utilities https://dilwyn.qlforum.co.uk/utils/index.html can create blank floppy disk images.
Also does your Thor have single sided drives, or do you need to enter something special to force it to do double sided.

As far as I know, the Thor has always had 720k floppies.
