lost windows partition file system after mounting under linux

Hi guys, I'm a linux newbie. Recently I mounted my fat32 partition under Linux and chmod 777 the directory in which it was mounted on. I shutdown my system without unmounting the fat32 partition. The problem is that now this partition has lost its file system and appears as unformatted under both linux & windows. However I did manage to do recover the data from the partition. My question is how can I restore the file system for this partition without loosing my data.

Thanks in advance.

When you shut down your system ALL filesystems were unmounted as part of the shutdown process, including the FAT32 partition. You lost partition information is not the result of Linux shutting down, you did make a newbie mistake however, Microsoft filesystems do not understand or care about Linux permissions at all (the chmod 777 bit).

To answer your question, restore from backup. You do not have one then lesson learned.

I would suggest that you take the time and truly fix your partitions issue and learn how to properly mount FAT32 partitions for use by non-root users in Linux.

Forgetting too unmount the partition shouldn't hurt anything. You do it everytime you shutdown. Unmounting partitions is part of the shutdown procedure.

Something else is at work here. Since you confess to being a Linux newbie, perhaps 'lack of knowledge'?

Open a terminal window, and run the command: fdisk -l

Post the return from that command.

Then we may be able to take it a step further.
