Avoid the built-in continuous backup software,
This review is from: WD My Book 1TB External Hard Drive Storage USB 3.0 File Backup and Storage (Personal Computers)
This review is for a 1TB USB 3.0/2.0 MyBook Essential running on Win Vista, 32-bit, fully patched, on a dual-core Intel machine with 4Gb of RAM.
WD supplies a "continuous backup" program that aims to keep your files automatically backed up at all times. This is a nice idea, but in practice, the "wdsmartware.exe" service is a total resource hog, using ~70%-80% of CPU with a 300Mb virtual memory size, 140Mb working set, running at "normal" priority. It makes logon time intolerably slow, and it slows down all other interactive desktop actions. It is simply unworkable, and you will need to uninstall it. The drive can be accessed and used without it.
