I used to do the update whenever available. For the past few days i was not able to create/paste/delete/ a file or folder in 3 out of 4 NTFS drives in my laptop. I couldnt even unmount the drives. 1 out of 4 drives has write access.
Previously i used to mount a drive to use, but nowadays its been already mounted. I'm using the latest kernel as per the update but forgot the exact number.
I also recently installed Bitdefender unices, does it change any security settings.
PS: I tried the above processes with root permissions also.
