hi swapnil ,
if you are still having problem accessing your NTFS then follow the below steps:
1)Go to taskbar menu select "Install & remove software" & enter ur password when prompted.
2)In the Search box above enter "NTFS" & u will get a list .Select the available packages and click Apply.
The requested drivers will be downloaded.
3)Then after download finishes go to Menu in taskbar select Tools/System Tools/NTFS Configuration Tool
and Enable Write support . If it doesn't work do it forcefully.
