I'm on a fresh install of #!Waldorf, have done a dist-upgrade and experience very slow write speeds to USB, especially with large files. I know this problem from my Ubuntu install. There it has been solved by the devs already.
Now this seems to be a common problem with the 3.2.0-3-amd64 kernel from what I read on Debian Bug Tracker: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=684630
And it seems to still exist after dist-upgrade to 3.2.0-4-amd64
There are suggested solutions from https://bbs.archlinux.org/viewtopic.php … 6#p1033186 that don't seem to help with #!
Another suggestion I found at http://forums.debian.net/viewtopic.php? … =0#p450178 involves the dd command like:
dd if=myfile of=/media/usb0/myfile oflag=direct obs=64k
I tried it with a 1.5G file and it worked like a charm.
Now I'm looking into making a custom action for Thunar. Something like:
dd if=%f of=/media/NAME_OF_MOUNTPOINT/%N oflag=direct obs=64k
And here's where the trouble starts.
I need to have a bash script that detects the inserted USB flash drive and it's mount point so I can replace NAME_OF_MOUNTPOINT with the proper mount point.
After a search I found some potential solutions at http://www.unix.com/shell-programming-s … rives.html. But they seem to be quite complicated. The one's I tried, didn't work on my system.
Anyways, in the Thunar right click menu there is an entry 'Send to' which nicely lists all mounted USB drives. So why not use that code, I thought.
But I can't find the relevant code. It is neither in ~/.local/share/Thunar/sendto nor in /usr/share/Thunar/sendto/
Can anybody help putting together that custom action or, even better, provide a general fix for the slow write speed in wheezy?

You may obtain the mountpoint with the following:
mount | grep -o "/media/usb[0-9]"/%N
Regarding slow usb speeds, try to adjust tlhe block option on dd, this works fine for me:
dd bs=1M if=%f of=`mount | grep -o "/media/usb[0-9]"`/%N
