I checked the thing, now I'm getting the old high speed USB transfer.
Do take a look at it, and comment.
Yes, but you should keep in mind that you'll spend extra time when you
want to unmount your USB stick. So I prefer a "slow" transfer and a
fast unmount, because usually I'm in hurry for taking off the USB
drive and the unmounting visualizations are not very smart (only in
KDE SC 4.4 it is really usable).
Actually I was recently wondering a bit about the unmounting part,
especially with USB sticks. I do have udev rules, taken from the wiki,
in place that handle automatic mounting. There's also a unmounting part,
which afair removes created dirs, but I guess this is only called after
the usb drive is removed. It did happen more than once to me that a file
transfer seemed to be complete, but when I just removed the drive, the
data was gone. Is there a way to provide automatic safe removal? Manual
unmounting is a bit of a PITA, as you need to have a terminal ready,
guess sdN and type a line, where the device guessing part is the most
problematic. I tend to use /dev/sdN to make sure that I remove the
device from all mount points. Thanks for any advice.
I am no expert and am probably missing something here, but it should be
simple to create a desktop icon and/or menu option to issue the sync
command. That way you could have the speed of asynchronous mount and
clicking the icon or menu option before removing the drive will write
any buffered data to the device to prevent data loss if removing the
device without umounting. As the sync command syncs all mounted drives
you don't need to provide the /dev/sdN.
Ross.
Yeah exactly !
After copy your data to the drive, run the sync command or setup a
keyboard shortcut for it :-)
This will give you high speed transfer along with no data loss \m/
But if you're very forgetful to remove the drive without pressing the
keyboard shortcut for sync, then you're in trouble and this patch is not
for you.
Alternatively, you could write a bash daemon as per this tutorial:

which will check for a usb stick's existence and if its mounted, sync
every 15-30 seconds.
