I suggest you look harder for an alternative explanation.  For example,
if your Prefix is set to a volume that is no longer online, a program
you launch could easily be looking for a file in the current directory,
or even temporarily setting the prefix to its *own* directory, and then
trying to set the prefix *back* where it was (to an offline volume).
This would scan all your drives.
