FloppyEMU HD20.dsk issues on SE

I have a new FloppyEMU rev C board updated with latest firmware.

Unfortunately, after downloading the linked HD20.dsk from https://www.savagetaylor.com/downloads/downloads-macintosh/ and copying it to it’s own subdirectory on the SD card, when I select it in floppy emu I get a “file not contiguous” vs FloppyEMU saying that the “startup disk has been saved” as it does with the default HD20.dsk supplied on the FloppyEMU SD card.

The dsk file opens up fine under mini Vmac emulator.

Any ideas?

Update:

The error is implying a disk fragmentation error. All files were copied to SD card today, so I doubt that.

Tried formatting the card and copying files again to defragment- no luck.

Copying the HD20.dsk on its own to the root of the SD seems to work but kinda defies the purpose.

Any clues?

Ran into this issue myself with my rev C on my SE, never had the issue with my rev B. It originally started with a read state error.

Reformatted the SD, re-copied just the one disk image, still got a "file not contiguous" error. The only other spare micro SD's I had laying around are cheapo's that the floppyEMU doesn't like, or massive 128GB microSD sandisks. I may try a sandisk out of morbid curiosity at this point, but last night I ended up setting the floppyemu back to floppy mode, and figuring out how to mount the SD from my extra SCSI2SD in Basilisk.

Edit: found a spare 16GB sandisk, copied the 2GB disk image to that, and the floppyEMU is happy again. Definitely be careful your brands of SD cards, as always nowadays.

Another edit: I spoke too soon, now I'm getting "READ STATE CHANGED 2" on the FloppyEMU :/ MacOS offers to format the disk and then is unable to.

I've emailed BMOW at this point, I cannot get this thing working in hard disk mode again, but I'm sure that BMOW will come through.

Ok, so I think I've narrowed this down to having something to do with the micromac accelerator.

If I boot with extensions off, effectively disabling the micromac, the FloppyEMU works in HD20 mode again. If I reboot with the accelerator enabled, I get the read state changed errors.

I let Steve/BMOW know... this happens with both Rev B and Rev C on the newest firmware. Hopefully there can be a fix, or someone else can try to reproduce this?

I have read that SE/30 may not support HD20 in which case that might explain this, seeing as the processor/FPU on my accelerator are that of an SE/30 for all intents and purposes.

The processor and FPU don't matter here. The SE/30 doesn't support the HD20 because the driver for the HD20 isn't in the SE/30 ROM. If your accelerator uses the SE ROM, the driver should be there (though it might be broken by the accelerator in other ways, I suppose)

Well... FWIW, I also get this READ STATE CHANGED 2 error when trying to use my FloppyEMU (also Rev.C) in my SE with my Total Systems Mercury 030 "on". If I disable or don't load the TS Mercury Extension, I can boot from the FloppyEMU in HD20 mode.

Thanks for that info, it definitely helps!

No worries here as I have my scsi2sd transport set up just fine but it would be interesting to see if it could be made to work. Probably more effort than it's worth for myself.

Also the rev B does the same with the accelerator, now that I did more testing. Not a surprise though as they both have the newest/same firmware.

Just to cross-post in case anyone else hits this ...
It looks like "Accelerators" do not play nice with the Floppy EMU's HD20 mode. Does anyone know if Steve from BMoW is still active here? Anyone know his ID?

Also chiming and confirming that Accelerators seem to be an issue in HD20 mode. I've got a Mac SE with a Radius Accelerator SE with a 68020 and I get the same "READ STATE CHANGED 2" error. Reformatting and copying back does not help. I've tried multiple images.
