This command does not work with USB flash drives that have a write-
protected primary partition. The partition will not mount properly. The most
common examples of these are drives with U3 software installed. In order to
log using these drives, this partition must be removed. Reformatting the drive
is not sufficient. According to the U3 web site:
“Most U3 smart drives come with an uninstall utility that converts the U3 smart
drive into a regular USB flash drive. This utility can be accessed from the U3
Launchpad. Open the U3 Launchpad and click on Settings, then select U3
Launchpad Settings and click on the Uninstall tab. Some devices have a link to
the Uninstall utility u
nder Help and Support.”

This command requires that at least 10% of the drive be free before logging begins.
Also, it will automatically stop logging when free space drops below 1 MByte.

After power cycle, file logging is in STOPPED status. To avoid file system
corruption on the USB flash drive, always stop file logging before removing the
flash drive.
