Thunar, USB-sticks and big files
Hi guys! I have a problem copying big files to an USB-stick using thunar in Debian Stable. Doing the actual copying is mostly fine and no error is printed, but when unmounting the USB memory (I guess it is then the files are actually copied) - the device pretty much always times out, giving an error message, and the copied files are not readable. I do this to copy ripped DVD's to USB memory for viewing in a TV with USB connection - the result is that if the files are copied using Thunar, it fails, the files are not readable by the TV, but if copying using terminal and a simple cp, it works just fine. Has anybody seen similar results - is there anything to be done to solve it? Nothing extremely serious, I can still copy the files using terminal as I said, but it would be nice to have it working using only Thunar too. -- Andreas Rönnquist mailingli...@gusnan.se gus...@gusnan.se signature.asc Description: PGP signature

The current version of teh command line umount does seem to wait until all data are flushed to the drive before exiting; older versions, IIRC, didn't necessarily wait. Hmmm. You said 'timeout'. Could it be that Thunar doesn't wait long enough? See if there's a way to increase that timeout. 10 seconds generally ought to be long enough, unless you have a *very* slow flash drive. Or, if there's a way to do it, tell Thunar to mount using -o sync; this should disable caching (that is, make the effective policy 'write-through'). Writes will be slower, but you won't have to wait for the flush to complete when unmounting. -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of unsubscribe. Trouble?
