Disk imaging software

I need to make a disk image (not clone) of my current disk on my laptop. I tried Laplink’s DiskImage. It didn’t work. Laplink tech support says it is not usable on a WD My Book drive.

What disk imaging software is compatible with the WD My Book and it’s software?

Look in downloads on WD site they have a modified version of Acroins True Image. Acronis also has a try and buy deal. I’ve used Acronis for several years. I make my image by booting from the boot disk.
