construct.core.StreamError: Error in path (parsing)

[ezaspy]

I have followed the updated instructions for setting up a venv and have ran into the following error:

$ sudo venv/bin/python tools/INDXRipper/INDXRipper.py -w csv -o 576716800 /mnt/i30_disk1.E01/ewf1 outfile

construct.core.StreamError: Error in path (parsing)
stream read less than specified amount, expected 3, found 0

I have two offsets for the disk:

• 2048 (x512) = 1048576
• 1126400 (x512) = 576716800

And I can't not run it as sudo, as the mount point permissions for /mnt/i30_disk1/ewf1 cannot be altered:

chmod: changing permissions of '/mnt/i30_disk1.E01': Function not implemented
chmod: changing permissions of '/mnt/i30_disk1.E01/ewf1': Function not implemented

INDXRipper expects the offset you give it to be in sectors, not in bytes. If 2048 is the offset in sectors, don't multiply it by 512.

Excellent, it works. My bad! Thanks again
