Re: How USB works?

Depends on your OS and how the drives are seen by it.

Many times, the removeable drives' file operations will be cached by the OS - the OS cache usually resides on the C: drive with the OS. This is why you should always "stop" the devices before you unplug them... this forces the OS to write any remaining data it has buffered to the intended destination.


If you have a USB hub w/ two drives on it and you copy files between them, there is an excellent chance the file data is being cached on the C:\ drive during the operation.
