Let's clear up the FUD (Fear, Uncertainty & Distrust) Surrounding The Norton Utilities suite of tools.
The only tool in the Norton suite which caused problems in the past is Norton Disc Doctor, as the early version for OSX were poorly written, and the version for OS9 was also not suited for use on an OSX type system. While Disc Doctor is better now, I would still recommend an alternative if you are repairing your disc (Discwarrior etc).
The REST of the tools in the Suite have had very few issues, and NONE to my knowledge with Norton Unerase/Undelete (I forget what it is called in the later version) which is what you would be using to recover your files. Neither is there any issue with Norton Speeddisc, should you be defragmenting your hard drive (to the best on my knowledge, it is the only consumer Mac app that truly defragments data for Mac OSX (unlike some other which only defragment the directory structure). And for those who suggest that fragmentation isn't an issue on Macs - they obviously don't deal with thousands of reasonably sized file on a regular basis, in an environment such as a art studio, video editing facility etc.
