Thanks for the tip. Using Konqueror, I unchecked the options "Synchronous" and "Acces time updates". That helped; now the copy-to speed is as fast as the copy-from speed.

What do these options actually do? Are they not safe to use as long as I use the "safely remove" function before unplugging the USB disk?

this if perfectly safe is you use "safely remove" (or do a "sync" command) the slow mode writes immediately, but thus by small chunks, so the slowness, but then you can unplug the thing at once. this is unnoticable if the computer is iddle, but in case of heavy disk load the writing can be delayed some seconds, and in case of very big file some minutes (I use a 300Gb HDD, so video copying needs some time :-) jdd -- http://www.dodin.net http://dodin.org/mediawiki/index.php/GPS_Lowrance_GO -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

in kde, right click on the device and look for a tab with options, some are faster (but less secure, don't remove the usb device too fast)

Look for the description of the options "async"/"sync" and "noatime"/"atime" while issueing "man mount" A coarse explanation: With the "sync"-option each block is forced to be written to the drive as soon as possible. This takes some time. With "async" the buffer gets written in larger chunks. A problem could be if one disconnects the drive to early. In this case the file system could be corrupted because not all data are written to the drive. -- Never give up ! Best regards / Gruß, Reinhard. "Software is like a parachute.
