Imaging linux ext3 not working

Hi all,
I am trying to make an image from a linux workstation with these partitions:

Linux native (raw) 250
Linux ext3 5114
Linux ext3 21289
Linux ext3 49661

It starts with the linux native, and it finishes, but when starting the second partition program shows the "Unknown error 32".

Tested with zen 7 sp1 and sp1ir1, tested one ext3 partition only, same result.

Thanks for any help.
