Yes you can, and it’s awesome.  It took about 10 minutes, and about 10 screws.  But why would you?  Well I’m glad you asked!

I robocopy all my DVD’s up to a couple of Western Digital My Books.  That way all my DVDs are at my fingertips, and it stops my little man from putting vegemite toast in the DVD drive of the Media Centre :)

The My Book upgraded from 500gb to 750gbBut Christmas Santa gave me quite a few DVDs.  So it’s time to copy them up, but I’m out of space.  So I bought a couple of WD 750 SATA disks on special.  $200 AUD each, a bargain!

The upgrade was quite painless:  popped of the chassis of the My Book, removed the cage screws, removed the drive screws, one screw out of the PCB.

Then I just popped in the new drive, put it all back together, plugged it back in and Voilla!  The My Book is now 250Gb larger.  I’m just copying over all the content from the old disk now.  ….23 minutes remaining.
