foreach my $process (in $sobj->InstancesOf("Win32_LogicalDisk")) {
next if $ignoreDriveTypes{ $process->{DriveType} };
So this would evaluate to true if $process->{DriveType} matches a key in
the hash?
It would evaluate to whatever $ignoreDriveTypes{$process->{DriveType}} is.
If $process->{DriveType} is a key of %ignoreDriveTypes, it'd be whatever
that key's value is. Otherwise, it returns undef (false).
If, by some bizarre coincidence, 0, '', or undef would be a valid value
for the key's value in the hash, you would need to use
next if exists $ignoreDriveTypes{ $process->{DriveType} };
which ignores the actual contents of the key's value, and just checks to
see if the key is in the hash.
