The ext2/3 Windows driver doesn't support extents yet so one common use would be to do a mount -o remount,noextents and make a dir and copy the files you want to read from Windows to it. I think mount -o remount is something that is well known, if you use tune2fs you would need to do research before you know if the change starts working right a way or after a reboot or if it is valid only until reboot or is static, with mount -o remount there is no risk that you forget to set the flag back to the right value.

Also when I tryed tune2fs as you said, I got the following error message:

peter@sanna:~$ sudo tune2fs -O ^extents /dev/mapper/sannavg-home
tune2fs 1.41.4 (27-Jan-2009)
Clearing filesystem feature 'extent' not supported.
peter@sanna:~$
