On Fedora Linux I had some really strange error messages 
when trying to copy files from my hard drive to a USB flash drive.

I identified the errors as being due to the fact that the 
USB was automounted by the kernel.

I think this was due to the flash drive being formated as 
FAT32, which caused it to be automounted.

I reformatted the USB stick as an extended partition, with 
an ext3 logical partition inside that.

It did not get automounted by the kernel. I mounted the USB 
flash drive by hand and the errors went away.
