Re: Volume Serial No

How much cases with 0 did you get? You can consider someone changed his
volume serial number using tool like this:

Hello Volodymyr ,
Thanks for your kind help.
Now I am more delighted, but my question is still unanswered.
Using "GetVolumeInformation" api's "lpVolumeSerialNumber" returns 0 from
some computer. Acording to the info you provided this api should return a
valid numeric charecter in dword.
Why is that occuring or my understanding for this subject is wrong ?
Regards.

On some computers we are getting 0 (zero) as volume serial number. We
are
wondering why it is so. The serial number should allways be dword and
numeric.
That is why we want to know its logic and method whether it is allways
produced as a number or something else.

what

AFAIK the Serial Num is a hangover
from DOS decade to be aware of a disk

To get this data either use WMI, DeviceIoControl,
or GetVolumeInformation to request this information,...

When windows formats a disk it gives a volume serial number to
that
disk
or
to a partition. What is the logic or method of assigning volume
serial
number
to the disk or to the partition ?
Kind regards.
