When I use the function GETVOLUMEINFORMATION() of the KERNEL32.DLL, it returns an integer number on the 4th parameter that gives-me the drives serial number in integer format. Translated to hexa-decimal, this number is equal of the number displayed on a command prompt window with the command LABEL or DIR.

A strange behavior has ocurred: when I run this function on a computer that has partitions on HD (windows / linux), it returns other value on drives serial number, different that obtained on command prompt.

Someone could give-me a idea of how to obtain always the same number that the commands DIR or LABEL display?

Really thanks for any replay.
