dvdcopy powershell script

PowerShell: DVD copy automation script V2.0

Requirement

I have a bunch of DVD’s that I want to archive to hard-disk so I can dispose of the DVDs.

Automate the process as much as possible.

Note: This is not a DVD copy protection crack, the DVD’s have to be copyable by the OS.

Synopsis

This script will wait for the DVD volume name to be NOT NULL

When a DVD is inserted, the script automatically creates a new folder in the destination root path, using the DVD name as the destination folder name.

After completing the copy it ejects the DVD drive and loops back into the waiting state.

Features

  • Disk insertion detection (not based on auto-run)
  • Destination folder name duplication protection via folder-name suffix (this prevents DVDs of the same name overwriting each-other)
  • Simple copy integrity check using source and destination length comparison
  • Speech so I can hear it from the next room when the DVD needs to be changed out

To Do

I’m wondering if using [System.IO.StreamWriter would be faster, but I think the bottleneck would be in the DVD Read, not the disk write.  Speculation only.  Next time I use the script I’ll make that modification and see how it goes.

<# DVD Copy Script V 2.0
 
     This version speaks so I can hear it from the next room when it needs a new disk

 SYNOPSIS ----------------------------------------------------------------------

     I have a bunch of DVD's that I want to archive to Hard Disk so I can dispose of the DVDs
     I want to automate it as much as possible.

     When a DVD is inserted it automatically copies the DVD to a destination folder root
      using the DVD name as a new destination sub-folder
 
     After completing it pops open the dvd drive and loops back into waiting for disk mode
 
     This version uses speach so I can hear it from another room!
