Re: Today I received.....

Nice drives. =D> Now a 5.25", 3.5" AND a Gotek in the same case would be amazing! Is it possible, I wonder? Physically fitting all 3 into a full height case would be possible, using something like this for the Gotek and 3.5" floppy: https://www.thingiverse.com/thing:4237727 But you l...

Re: Today I received.....

Not so much received, but finished building. All working really nicely. The switch at the LHS of the 3.5" floppy drive is used to toggle which drive is drive 0/2, and which is drive 1/3 (or drive 0/4 & drive 1/5 for ADFS). I'm going to add the same switch to the Gotek / 5.25" floppy dr...

That HxCFloppyEmulator version looks a bit old. I have v2.5.6.7 and I took the first HFE (Elite) and it loads fine.
Ah. Just downloaded v2.5.6.6 (couldn't find v2.5.6.7 at first glance) and that seems to have fixed it.

Edit: Found v2.5.6.7 as a Beta download.

Thanks

Re: Starting an archive of HFE protected disc files

Do you know why the HFE files in your archive (at least the ones I've tried) won't load into HxCFloppyEmulator? Can you give a link to a specific HFE or two? And I'll check them out.

Re: Disc rot on 5 1/2” disc

Re: Starting an archive of HFE protected disc files

You've been unlucky! The early Level 9 protection is _not_ 1770 compatible and is expected to fail with exactly that error code $0E. I think the catalog or !BOOT sectors declare themselves as 512 bytes or something like that. The 8271 can read them as 256 bytes by force anyway, but the 1770 is only...

Re: Disc rot on 5 1/2” disc

After removing the disk from its sleeve I tried the isopropyl alcohol on an unused part of the disk, but it left a horrible residue, so in the end I just used a cotton bud and some water. The marks are still on the disk, but it otherwise seems to be working ok: https://stardot.org.uk/forums/viewtopi...

You can clean it with a cotton bud and distilled water. I have a load to clean I keep putting off :lol:
Does it need to be distilled water? What would isopropyl alcohol do to the disk?

I think it's because they're easier to work on, with most chips being socketed, which then allows more internal upgra...
