So I had a few large files to copy, about 5GB each. From/to same partition. Start the copy, it says '3 minutes left', so I think....a quick solitare game. And poof...system hangs. Nada. Nothing. I wait about 5 minutes, and nada...mouse is obviously not working. Power down, reboot. And of course the new directory I was copying to doesn't even exist after a reboot.
When copying large (or even files of a few KB) to an sd card from ubuntu 10.10, 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 - im just doing it from cmd line.
