Hello and welcome to the forums.
Sounds to me like there are some serious problems with respect to the disk and or partition(s) that is hosting your OS(s)
a device has been unpluggedi try to open the win8 partition a Message appear telling if i want to format and i can't access to the partitionNot sure why you decided to host critical data within a Beta OSi've tried to run chkdsk but disc is not recognized
But I suppose we have all been there in one form or another.i have 500gb of data there and a lot are important
You may want to try using one of the Linux Distro's (Live CD) https://help.ubuntu.com/community/LiveCD
And see if you can use that environment (independent of the installed OS(s)) to see if you can access your critical data on the problem drive / partition and copy it off to an external device for safety.
If the disk / partition is failing (bad sectors) then your options might be limited as any disk utilities you might attempt to use to examine the problem or repair it might also serve to further exacerbate the problem.
I guess the bottom line is that you are going to have to address the problem in some manner up to and including replacing the drive if necessary. But do try to secure your critical data first.
