If it helps I've noticed that one way to reproduce it is to use Azureus to download a torrent (eg an Ubuntu CD) and then copy a large file to the SD card. While it's doing this I get heaps of mmcblk errors and subsequent data loss. When I stop Azureus so the system is no longer under load and try copying to SD again the errors (usually) go away.
