I tried > skip=28672 to no avail as well. Anything did I do wrong? I have not any Vbox images with fixed size, but i tried this: # mdconfig -f 10G_GPT_UFS.vdi # gnop create -v -o 41472 /dev/md0 where 41472 is offData value. After that md0.nop was tasted and reports about invalid GPT. So, i think if your image is fixed size disk yout can try this method and mount UFS (not cd9660). -- WBR, Andrey V. Elsukov
