Found slave hard drive, but can't open folders or files

[Daniel Saunders]

It's probably a problem with permissions then.  You probably want to
mount the hard drive with umask=022.  Maybe reading 'man chmod'  will
help you to understand this command, but it willl give everyone
reading and executing permissions for the disk and allow the root user
to read, write and execute.  Alternatively umask=000 will allow
everyone read, write, execute privileges - though obviously it's not
as safe.
