My goal is to have a USB drive in ext4 and to use it as a normal Fat32/NTFS pendrive (or usb box drive). I would be happy to forget NTFS and Fat32 and to use this USB Drive with all pc in my local net. By the use of CHMOD and CHOWN I would create a REALLY everyone drive in ext4. Every mountpoint should be for everyone. Tons of command line rows are written but no tutorial and simple procedures to make it possible. Thanks.
If you want an owner/group-agnostic file system for your drive,
ext4 is not the right one for you.
As a workaround you could use a bind mount if you have
sudo, but that is probably not what you want:
sudo bindfs -u $(id -u) -g $(id -g) /media/diskFoo ~/myUIDdiskFoo
I don't know of any suitable unix/linux/opensource permission-agnostic file system. Unfortunately, you should probably use
NTFS is a journalling fs and thus not suitable for flash storage).
