VBA to protect workbooks.

[baxius]

Hello, i'm thinking of implementing a safety measure to prevent the usage of the my workbook by people who would really want to but shouldn't use it without my consent.
The VBA i'm thinking of is to check if a USB drive is present with a specific while on it. Looks something like this:

So my question is: Would it be a good idea to implement something like this? Maybe there are better methods? Won't this solution backfire by making accessibility of the workbook impossible?

Any help, insights and tips are really appreciated.
Thank you.

It’s largely a waste of time, to circumvent that, one could simply disable macros. It’s also trivial to change VBA code regardless of the measures you put in place. As long as you’re only trying to prevent casual use though, you should be fine, just be aware you can’t stop someone with a bit of know how or willingness to google!
