I need my script to get the size (Preferably in bytes) of a hard drive, I tried this: my $Size = (-s "/dev/sda4"); but it always sets $Size to 0.

Since this seems very OS-specific it may be sensible to use OS-specific tools. Anyway a module like Sys::Filesystem seems like a good start. I found it with a few seconds' CPAN search for Linux device. Other searches may return more appropriate results for you.
