I have been looking and I do not see any syntax errors. any suggestions?

Yes, you completely dropped the creation of the OLE filesystem object, thus $fs is left undefined. And you dropped the error message from the die statement.

my $fs = Win32::OLE->CreateObject('Scripting.FileSystemObject');
my $d = $fs->GetDrive('Y:') or die "GetDrive failed $!";
