Hi Brian, Backing up to a hard disk is very cool and convenient and, as you point out, not really that expensive. And with the HUGE capacity you can do complete backups of your system each time instead of doing incrementals most of the time so you can leave it unattended and be confident it will fit on a CD. The problem is that all the time the hard disk is in your computer, it is susceptible to the following problems: disaster (your house burns down) power spikes (which could cause the heads to scratch the disk, meaning the only chance of ever getting data off it again is to send it to an expensive data recovery service) malice (someone doesn't like you so they scribble on the backups) accident (someone mistypes something and ends up scribbling on your backups) Just make sure you're safe from the things that you want to be safe from; that's all I'm saying. If you can afford for your last backup to be slightly out of date (i.e. to the last time you took a disk out), and you think the chances of the above are small enough, then go for it and enjoy the convenience!
