I have read this question/answer and found that an USB stick could have a serial number associated with it. This is an intersting info for my project but I wish to know if a re-format of the USB stick could wipe away the serial number and generate a new one.
Oh well, I could try it by myself but at the moment I have no usb stick to format.

  • A device like a USB pen drive should have its serial number fixed in ROM/firmware. A Harddisk partition otoh can also have sort iof serial number (UUID). Which of these are you referring to? – Hennes Feb 12 '16 at 13:25

  • The firmware one. But of course, if it exists and it is possible to read it then I have the answer. Thanks. – Steve Feb 12 '16 at 13:53

No, the serial number will be stored in the firmware of the drive, which is likely read-only and set in the factory when manufactured.

It certainly wouldn't be affected by formatting the drive.

    All right, finally I have managed to test a pendrive with some utilities and the SerialNumber is not changed by a format. – Steve Feb 12 '16 at 17:19
