Re: [Clonezilla-live] Clonezilla / Partclone ext4 problem

[Andreas W. <and...@nt...>]

Hi,

I ran fsck on the disk and I also verified the image using a SHA1
checksum. The image is rather large and contains sensitive data.
However, I will try to create an image with smaller size and without any
sensitive data showing the same problem. As soon as I succeeded in doing
so I will provide that image to you.

Regards,
Andreas
