That seems to speed things up alot. However I can't unmount it > again, I keep getting "umount: /media/usbdisk: device is > busy" (twice(?)). It's been 5 minutes since I did the transfer (4 MB > file) now. Err, I accidently mixed up the device names of my keyring and the mp3 player. It works allright. (It flushes changes to the device when I unmount it now, which takes around 8 seconds for a 4 MB file.) Thanks a lot, Paulo! -- .-.
