hmm, I now I have tried several different USB-sticks, and I still have the problem (It perhaps isn't quite as serious as I believed though)... If having copied a "big" file, unmounting through Thunar pretty much always results in the following error message: > Failed unmounting 'Devicename' > "Did not receive a reply. Possible causes include: the remote > application did not send a reply, the message bus security policy > blocked the reply, the reply timeout expired, or the network > connection was broken." - after a short while (way before the actual writing is done) - But, if I keep waiting for some time _after_ this, the data is still written to the device as it should. However, it doesn't give any clue whatsoever to when it actually is finished writing the files to the device, so it is easy to (by mistake) physically take the USB-stick before the data is actually written. However, I do have one USB-stick, that actually lights up a LED during copying, making it pretty easy to spot when it is safe to remove it and not, but I kind of wish that that sort of feature wouldn't be necessary to safely use an USB-stick... If I don't copy any files, or just copy small files, I get that standard "It's now safe to remove the device" when unmounting - This is what I expect in the scenario with bigger files described above too after copying is done, but no... -- Andreas Rönnquist mailingli...@gusnan.se gus...@gusnan.se
