Does it deliver any bytes before erroring out ? dd if=/mnt/1mb bs=1 | wc -c Just to be sure, can you copy the ISO to a Linux machine with <= 32 KiB page size and verify that the file "1mb" is readable without i/o error and yields the due checksum ? (I am not aware how xorriso could have spoiled it, but ...) The kernel log shows no hint what's wrong. strace cannot, because the problem happens under mm/readahead in zisofs_fill_pages() deep inside the kernel. At least i know where to look for code flaws. I wonder whether this ever was tested in the last 19 years. Thanks a lot for doing it now. Have a nice day :) Thomas
