Hi There Last night I added the "date added" column on my exFat32 external hard drive. Unfortunately nothing appeared. "date modified" and "date created" are showing their respective dates however just some blank hypens under "date added". Its playing havoc with my music folder! After indexing a couple of times still no luck. Ive tried indexing through the system preferences add/remove mode and the terminal sudo method. What I have also noticed is that under downloads folder in the internal drive the date added column displays but if i transfer to the external it disappears? Any suggestions guys? Running Mountain Lion OS X 10.8.3. Thanks!
