I use Clonezilla regularly to back up my whole hard drive in Ubuntu 12.04.
Every time I ask Clonezilla to check the system before making the image file I get the following message:
"Free blocks count is wrong. Fix <y> ?"
"Free inodes count is wrong. Fix <y> ?"

I respond with y and all seems to be OK.

Is the problem due to a bug or am I doing something wrong?
