Can I conver/mount ext4 as ext2? Because I have pendrive flash disk and I heard that ext2 is better than ext4 but my installator forced me to ext4. Can I do something with it?

What is the real problem? Just format it again as ext2? Just use ext4? In what way would ext2 be "better"? –  slhck Apr 5 '12 at 10:05
    
ext4 uses journalising, which shorts pendrive life. –  oneat Apr 5 '12 at 10:12
    
I heard that I don't have to reformat it. Just change the type (?) or mount it as ext2 without losing data. –  oneat Apr 5 '12 at 10:17

You can mount ext4 with journalling disabled.

Most people don't seem to think there is a significant problem with journalling on a large flash-memory device.
