Can't change permissions on mounted FAT32 partition

[Vai Pandøži Trabian]

I have a FAT32 partition that is shared with Windows XP mounted under /windows. I want to set write permissions for all users for that partition, but when I use chmod 777 /windows nothing happens. The permissions remain rwxr-xr-x. The fstab options for the partition are rw and user, so the user should be able to write to it. How do I fix this?

try adding the umask=0000 to the fstab entry for the fat partition.

Here is my fstab entry for my FAT partition:

/dev/hdc5       /windows/E      vfat    iocharset=utf8,umask=000   0       0

I got that from www.ubuntuguide.org

IIRC FAT32 doesn't support all the permissions dealy, so I'm not sure if you can change them once they are on it.

Same problem: fixed with the following fstab entry
/dev/sda4 /windows/RW vfat rw,fat=32,umask=000,noexec,quiet 1 1

The umask thing should work as it sets the default permission for all the files on the filesystem - think of 777 - umask value = permissions of files.

So to set all the files permission 777, use umask=000.

Myself i use uid=1000,gid=100 instead to make me the owner of all files.

FAT filesystem doesnt support any permissions so you have to fake it

I'm new to Linux but have a little experience with it, using UBUNTU 11.04, I have an external 1TB USB HDD mounted to this computer which is running dual boot with Windows7. The HDD is formatted FAT32 and I've set the share options but the permisions for allowing others to access it say NONE and cannot be changed. I read through the threads and this one, even though it is from 2006, it seams closest to my issue but the things it says to do are not making sense to me... Does my issue sound like something that could be resolved by the above steps? if so can I get help on how to do so please?
