I've taken this into account, hence the second pass after each fsck. This is either a dosfsck issue, a usb-storage issue for the PNY compact flash drive, or an issue with vfat itself. So either LKML needs to fix the drivers, or Ubuntu needs to upgrade/fix dosfsck or some patch they've applied to the kernel. - -- All content of all messages exchanged herein are left in the Public Domain, unless otherwise explicitly stated.
