I would do it this way:
use Modern::Perl;

while (<DATA>) {
    my @record = split;
    if ($record[1]=~s/-$//) {
        while (<DATA>) {
            my ($continuation) = split;
            $record[1] .= $continuation;
            last unless $record[1]=~s/-$//;
        }
    }
    say join ' ', @record;
}

__DATA__
A00002   \\a00002\c$    2   WinNT   NTFS  Yes 73,626MB  42.5
A00003   /            1     Linux86 EXT3  No  38,289MB  29.8
A00004
A00004   \Sys-       1     WinNT    VSS  Yes  0 KB     0.0

And yes, you get a few "Use of uninitialized value $record1" warnings because of the anomalous third record which has only one filed "A00004" in it. You can safely ignore these warnings or add another test to drop such record if you do not need it.

A program should be light and agile, its subroutines connected like a string of pearls. The spirit and intent of the program should be retained throughout. There should be neither too little or too much, neither needless loops nor useless variables, neither lack of structure nor overwhelming rigidity." - The Tao of Programming, 4.1 - Geoffrey James
