You are using wrong cloop version

Which knoppix are you trying to extract and which cloop do you have?

Latest knoppix uses cloop 2.01

Previous versions used 1.02 and 0.68 respectivley

Hi,
while running extract_compressed_fs using the
KNOPPIX-file on CD and from the iso-image
downloaded from one of the mirrors I encountered
the following problem:
uncomp: input corrupt block xxx
Problem appeared always at different blocks - I never
got further than 6662.
Does anybody has an idea why or how to solve this?
I appriciate your help!
Solong
