The Volume Serial # Update dialog can be displayed by choosing Volume Serial # Update from the Tools menu. Its purpose is to allow you to tell PMIO about changes to volume serial numbers. You will rarely need to use this facility. It may be of use if you have to reinstall your operating system or have formatted a disk volume (formatting changes the serial number).
The Volume Serial # Update Dialog
Note: If the volume in question is not listed, PMIO doesn't know about the volume so you do not have to use this function.
Warning: You need to be extremely careful when using this facility. If you are at all unsure about whether you need to use it or not, it is best to not use it. Incorrect use of this feature can cause the loss of PMIO settings and memos.
