I was able to reproduce, CD to a directory causes a critical error prompt. I built a hard disk image like this: nasm -D_MEDIAID=0F8h -D_SPF=2000 ../bootimg/bootimg.asm -I ../bootimg/ -I ../lmacros/ -D_MBR -D_BPE=32 -D_MBR_PART_TYPE=fat32 -o big32.img -D_PAYLOADFILE=::fill,'(512 * 76000),26h,fill.dat,::chdir,testdir,::fill,32,32,test.dat' -D_SPI=256000

I am fairly sure that a SvarDOS contribution changing the LBA flagging is to blame: https://hg.pushbx.org/ecm/edrdos/rev/220f54eecbb8 From https://github.com/SvarDOS/edrdos/commit/99765bd4c9ec9e035f1bd2af191c35d440c99383

It changed the LBA use to be indicated by the UDF_LBA flag. However, in add_unit this flag is cleared: https://hg.pushbx.org/ecm/edrdos/file/1137afe0115d/drbio/disk.asm#l616

The next changeset will fix this problem, please test today's June build in 45min from now.
