I just recently started archiving by both Dvd's and HDD, I use to depend on my HDDs. I have
1 x 160gb,
1 x 300 gb, (external)
1 x 30 gb (external case)
1 x 80 gb.(external case)
I had another 160 gb but that one died recently sad to say, it didn't see that much use, infact it was a newer one.And was not used for anything, only because i didn't have an external case for it. But when i finally got one for it. The freaking thing died, my first hdd ever to die. But it did teach me how important it is to have Dvd back ups. So I burn all completed series and the ones that are incomplete or i watch often i keep, but i back up them. I hope you all learn the importance of backing up too.
