TRD format compatible with QL?

I connected a 1.44 standard Gotek onto my QL/Trump and it wasn't super compatible. Is the TRD (Spectrum TR-DOS) format usable, and of any advantage? It is one of the formats supported by the FlashFloppy firmware replacement project.

The Trump card is 720K. If you want to use the 1.44MB mode you need to connect it to a (Super) Gold Card.

I used to have a Gotek and many others have used them successfully.

No, Trump Card (andf QL) is incompatible with TR-DOS format (and its silly sector size 256 bytes).

What Dave says, the actual physical sector format is the same as a PC.

The QL also came with a CST Q-disc, any chance that is 1.44 compatible? I don't think the CST has any extra RAM though. No 720KB Goteks seem to be available easily any longer, which is why I inquired about the FlashFloppy firmware, which seems to be based on Lotharek's open-sourced floppy emu product.

The CST also does not support 1.44MB floppy disk drives - only the Gold Card and Super Gold Card support those.

I have used a HxC Floppy Disk emulator successfully with a range of disk drive units and even uploaded a little guide to using them onto Dilwyn's Sinclair QL Homepage - http://www.dilwyn.me.uk/docs/manuals/Si ... rticle.pdf
