Backup Hard Disk: Western Digital My Book 500

I bailed out on the sophisticated backup system by buying a Western Digital 500GB external "My Book Home" drive at Costco for $139. I really needed to back up my files pronto. So far, so good, but I did have to reformat it for NTFS, as it comes formatted as FAT32 (not a good thing).

One gripe: the included backup software, WD Anywhere Backup is a trial version, and not advertised as such. Also, it seems to be unable to backup my outlook.pst file and large .avi files. So far, the jury is out on whether it works well.
