Is there some Exfat weirdness between @BlueSCSI and Linux?
I formatted an SD card on linux, truncate(1)ed some images, installed using other disk drives. Installed off other media onto those disk images (one NT4, one DOS 6) but now if I look at those images on the Linux host they're blank???
I did also try putting the NT4 iso on the SD card, that fails to boot on the target machine, but now if I grep for some strings I expect to see on the hard disk images those show up in the ISO.
BlueSCSI 2 with firmware 2026.08.17-rel and Ubuntu 26.04 btw.
