I’ve a MyBook World Edition with a 1TB drive (a WD Caviar Green WD10EACS), and I’m wondering if anyone has experience in replacing that drive with a larger model in the exact same WD Caviar range of drives (e.g. WD20EARX)? Is it as simple as putting in a new blank drive and powering on, or do I need to mirror the drive contents across first, then grow the partition to fill the empty space?
you are correct, it is a bit more complicated than just tossing in a new drive. THe OS is on the drive, so you first have to install the OS, and you have to install the correct partition sizes.
There guides on how to do this on the wikidot forum.
