Hi Bob,
just like my approach was when I got my first Mac ever last year after 20+ years of MS-DOS and Windows 😉
But if I ever learned one thing from using Windows PCs, then it is 'save early, save often' .
A lot of the 'fear and avoidance' can be overcome when always having an uptodate backup of all things valuable.
It might be interesting for you that there is 'a new kid in town' :
Paragon has released its NTFS for OSX
http://www.paragon-software.com/home/ntfs-mac/ which I have to try out yet, but it seems that with it one might be able to use any kind of backup application in OSX to also backup the NTFS partition.
Might be making life easier with it.
Have Fun
Stefan
