Formatting a usb pen in fat32 using mkdosfs

8 posts · originally from https://geek.digit.in/community/threads/formatting-a-usb-pen-in-fat32-using-mkdosfs.105390/

After unmounting the pendrive, and using fdisk to set the partition as W95 FAT32, I used the following command

sudo mkdosfs -F 32 /dev/sdb1

Now everything was successful, but when I try to paste files as user I cannot because the owner of the filesystem is root (I had to be root to fdisk and mkdosfs).

So how do I solve this problem?

Re-Mount stick and set umask value to zero. Let say, /media/sdb1 is mount point ( folder ). In case it doesn't exist, create it.

Code:

sudo umount /dev/sdb1
sudo mount -vfat /dev/sdb1 /media/sdb1 -o defaults,umask=0

Regular user will have full privileges.

Thank you for your reply, will await other replies too. This is a manual method. I am ok with it, but not if I teach newcomers.

Please have a look at this thread also

Easiest but a risky way is, press Alt+F2 and type this

Code:

gksu nautilus

It will open Nautilus with root privileges. You will have full access to every file/folder. Risky, because you will root user and it not good to have root privileges in GUI.

I usually use mkfs.vfat to format usb on linux. Is this different from the method discussed here ?

Maybe the same?

Try adding the user to group haldaemon, since the mounting and things are controlled by hal.

mkfs.vfat and mkdosfs -F 32 do the same job. Both commands format partition in FAT32 filesystem in similar way.
