urgent help with hard disk doing wrong . please

Actually ICit2lol, OP has mentioned a few times that he has a lot of very important information on that external WD My Passport hard drive. So reformatting is out of the question in this case. Also, I think he's using one OS – Windows 7 (for which in my previous post I wrote Vista by mistake, but now have corrected it, so I apologize).
I hope he'll run the WD DLG Quick and Extended tests to see what kind of errors (and if) it will show for the drive.
But so far it seems like a lost partition to me, though, I would like to see a screen shot of Drive Management and continue from there.

Cheers!

I tried to go through the Device Manager -- but it doesn't give the option - Enable - only Disable.
The WD program show this picture :

I think the faulty drive is F - shown down and it doesn't give the option to go there

And also I tried with another computer and doesn't work too

Got news
I can sea the passport on My Computer with all the folders. But -- I can't get in !!!!
It says

Hi Edi77,

You have shown that F:\My Video is not accessible. Are you able to access the other folders?

There is no point in giving information in bits and pieces overlooking the information sought.

Please post a screenshot of Windows Disk Management as already sought by others. Your screenshot should be a full Window of Disk Management hiding the Console Tree and Action Pane.

Disk Management - Post a Screen Capture Image

Also post a screenshot of how the drive looks in Partition Wizard.

The picture of the Computer management is :
