This page is a repository of the online and software tools that I use. It is by no means exhaustive or representative of the best offering in its given category. These are the tools I have foundto get the job done in the way I need it done.
SpinRite - Yes, there are ways to kick a disk into gear with dd and afew other Unix commands, but sometimes you just need to set it and forget it and get a little feedback from the process.
NirSoft - This guy pretty much creates all the tools that should be built into Windows and Sysinternals has not addressed. I have use more than the list below, but theses are the ones I use most frequently.
