F:\ is not accesible, Access is denied

hi guys, i want to expand my F drive into two partitions.. i started doing it so by "Disk Management Utility" and accidently cancelled the process in the middle of it. After this, i m receiving this error on my F Drive.
F:\ is not accesible, Access is denied

When i checked properties of F drive, it shows used space = 0 bytes and free space = 0 bytes.
But in Disk management, it shows 108 Gb total, and free 108 Gb

Can anybody help me in resolving this issue?
i have very imp data on this drive..

You nee to add the permissions to it.


Click on Start --> In search box, type cmd. When the cmd appears in the
search list, right-click on it and select "Run as administrator".
"Command Prompt" will be opened.
Since access denied message appears only for F-Drive, enter the below


commands
takeown /f f: --> Press Enter.
icacls f: /grant username:f --> Press Enter.
