Running Win 7, decided I would unpartition my F: drive (to gain a whopping 100MB). I 'unpartitioned' it by deleting the smaller partition and making the disk a dynamic disk. However upon doing this I found out I had lost access to it. I can not open it, and I can't set a new owner.

I got to properties>security and see this. So I obviously clicked advanced as you can see in the picture. So I press continue Brininging up this, I select the admin account (mine), press apply and get this.

Looking online people have this issue with external hard drives or individual folders. The only thing I can think is to format it, but there's 1.5TB of data on there and I can't access it to make a backup (my previous backup of it has been damaged as a result the backup was lost).

So I'm wondering; did I dun goof by making it dynamic or can I recover access to it without losing data?

Thanks

Update: I can't run things like defrag, and disk cleanup. The drive appears in disk cleanup however when selected it says "Disk Cleanup cannot clean up drive F:\. Make sure that there is a disk in the drive." And it outright doesn't appear on defrag


UPDATE: Solved my own problem by using the age old adage "have you tried turning it off and on again". I'm leaving it unsolved due to a sub question I have; Dynamic vs Basic disk, what's the difference and is one better than the other? The Dynamic disk contains multiple media files (video, audio, and pictures) and all my basic drives have pretty much everything on them (pictures, videos, instillation files, games, etc.)
