OK. I won’t. J


I was trying to read up on the subject as best as I could. From what I understand, most of what the 64bit format provides is bigger block sizes and a larger filesystem (+8TB). However, I only have drives in the hundreds of GB not in the TB range (I wish…but don’t we all). It is my understanding that 64bit carries full backwards compatibility, but I really wanted to verify first. So now all that is left is to give the upgrade a shot and see what happens.


Besides…I have backups. J


Thanks for your input guys!
