Possible Duplicate: Copying files to SD card not saving
When copying large (or even files of a few KB) to an SD card from Ubuntu 10.10 (Maverick Meerkat), the files appear to be there, but when I access the card from another device, the files are either missing or 0 bytes in size.
I suspect that the problem is that it takes time for the files to copy to the card and I'm taking it out too soon, but there is no progress bar - I'm just doing it from the command line. And it even happens when I cleanly eject the card.
Is there a preferred way to do this so I can know that the files are copied?
