I recommend this highly.

Two drives:
Drive C - operating system
Drive D - Storage, everything else.

On drive D I keep not only documents, spreadsheets, etc, but also copies of installable applications, notes, drivers, etc and also GHOST image of the operating system drive upstairs!!!! Restoration is easy.

Redundant copy of Drive D also maintained, one on a networked station downstairs and USB drives.

As I support corporate computers, I fear home computers and do not enjoy working on them, tooooooo many things can be so bad and weird there, and home users do not understand what a rebuild entails, or hours of diagnostics performed. Then put little Tommy back on it again ......
