[Bug 43651] Engine Prime: can only add tracks if under C: drive

--- Comment #7 from Adam Szmigin  ---
Possible hint from the Denon DJ FAQ:
http://denondj.com/kb/article/2236#read_only
> Why can’t I add songs from read-only media to my collection?
>
> Engine Prime creates and stores the database on the same drive(s) that store
> the tracks. This means that drives/media must have write access enabled to
> work with Engine Prime. Typical read-only situations include locked SD cards,
> CDs or other ROM media, and 12” Vinyl Discs.

I'll test this out.
