But ... ... and there is a thread on the linux kernel mailing list about it ... ... you stand a chance of destroying the flash drive because of the updates to the FAT tables during the write process. [I think someone wrote a 1GB file to a large fat drive and fried it in the process] What the grandparent post wants to do is controlled by HAL parameters.
