@TheMogMiner has done some sterling work, as has @AshEvans81. Are there still any boot assets still on the HDD that no one else has?

I am still keeping it safe, *IF* i do get the PB running, i can connect the HDD and see if anything happens.
Honestly, talk to Ash. Based on the signal protocol that the Paintbox's disc controller uses it should be relatively straightforward to just step through each head on each cylinder and crap the bytes out into an SD card or something similar.

Sure. Header mark, then 20k bytes of data. Metadata in the last 256 bytes of the last track, so you an identify last tracks and they should then give a size. Directory starts track zero, fixed size file descriptors, file zero is directory itself.

Is that for the 8" floppy?

I still have this mahoosive NEC SMD drive sat on a shelf. lol Along with the buffer board I made for the SMD interface. But I used the same chips for read/write data as for control, and they didn't seem fast enough to even write an MFM track at ~8 MHz.pic.twitter.com/lSietRByzF

So it got literally shelved, as Mark was getting the original Fujitsu "Eagle" HDD looked at etc. I was just using the DE1 FPGA board and some very basic Verilog to move the head position etc. That part seemed to work fine. But writing/reading the data didn't seem to work right.

Working with the M2294 is never straightforward! It's a absolute thicc angry unit!pic.twitter.com/plDvFGaLOc

Considering its age, those bearings don’t sound THAT bad. :)
