The reason I asked this question is because I read that with JPG files
a single pixel error can ruin the whole photo but is not noticed i a
TIF file. I didn't know DNG files were TIF files. So I should be ok
saving directly to DNG in the camera and making a JPG copy for
viewing.

What camera are you using? Most camera-produced DNGs are
uncompressed so they're fairly immune from harm by
single-bit errors. Personally I've never had a DNG lost by
data corruption - not one - and all my DNGs are compressed
from various raw camera formats using the (free) Adobe DNG
Converter. My current DNG count exceeds 30k.
