That is there because 99.9% of the usb disks use the fat file system, and yanking out a fat disk when it is still mounted can cause bad things to happen to the filesystem. As you are using ext3, your chance of lost data is _very_ low. And if you make sure you always unmount the disk before removing the cable, you will not have any problems at all. > I also get more feed back doing a copy now than I used to. > > #sudo time cp /srv/userdata/nathaniels/home/comtel.myo /media/usb0/ > 0.06user 1.91system 0:15.13elapsed 13%CPU (0avgtext+0avgdata 0maxresident)k > 0inputs+0outputs (0major+164minor)pagefaults 0swaps > > Whats with the minor pagefaults anything to worry about? > Any other side effects of takig sync out of that options list beside the > need for a manual (or scripted) sync before pulling the drive?
