For real media just change the offset so as not to include the 534 bytes of
header on the hdf file.
-Make a copy of the media as right now it eats the disks !

Debugging state:
-
-Looks like we may have some obscure interrupt corruption case or similar
-(we bomb weirdly late on or see a bit of random display corruption and
-fsck fails part way with corruption like results)
-
-Need to try cutting down IRQ handler. One mess was on the video display which
-suggests whatever happened occurred with the video mapped at one point (same
-char was later printed correctly)
-
-Disabling pre-empt doesn't help and fsck shows corruption in execution which
-suggests its not task switch related
-
+- Still chasing down a possible memory corruption bug that looks irq related
