I have had a 500GB SSD iPod working with Rockbox without any problems for the last three years, and a 250GB one for the last two.
Unpatched version doesnt load rockbox at all, regardless of what's on the device, it gives an "ATA error" ("-1" i think) on startup.
Apple firmware not an option as it has a file number limit (around 45000 IIRC) which I have exceeded by about 450% at this point.
I have removed some of the files and it now starts and has built a database. So either the problem is that I have some corrupted files or that Rockbox also has a file limit (albeit not by design). If it is the former case I would however like to know what the corrupted files are, so it would be helpful if someone could tell me what the error message means.
The SSD itself, btw, is brand new (Samsung 850 EVO).
