[SOLVED] Unable to make snapshots

[optimistic]

No difference my VM on or off I can't take snapshots.
After some configuring I made successfully one snapshot, then I wanted to make another one, but I cant.
Button Take Snapshot not active.
I deleted my previous snapshot, I have no snapshots at all, and I still can't make any.

What am I doing wrong? How to make snapshots?

Have you choose RAW Image format?

Have you choose RAW Image format?

Yes, you are right! I mounted one more hard drive in raw image.
I just removed hard disk in raw and made snapshot successfully.
Thank you
