A partition on one of my hard drives just died...it has to do with the failure of the filesystem.
It's a FAT32 filesystem, someone recommended i convert the filesystem to NTFS via command prompt with the method i posted above, this way i was able to repair the filesystem by converting it without losing my data.
Command Prompt gave an error when i tried to do it...so i wondered if it'll work when doing it under Linux.
What was suppose to happen under windows was that the task got scheduled to convert the partition on the next reboot...i should have had a prompt popup asking me if i wanted to do that, but because windows gave me an error before i got the prompt the task couldn't be scheduled.
So that's why i wanted to try it via Linux.

But i guess if it isn't possible i'll probably have to recover my data via some recovery app and reformat the broken partition.
