For the last two years I've been trying to archive my large (26 GB) Home movie DV data files. I've made over 30 burns to (mostly 25 GB) Verbatim BD-R media.
The problem is, almost all of them seem to 'go bad' within about a year of burning them. I'm getting pretty discouraged, and can't seem to figure out what's going wrong.
I started out about 2 years ago with an LG GGW-H20L and CyberLink Power2Go/Nero. All were 'verified' when they were written.
About a year later I ran Nero Discspeed on them, and many were all 'green' except for the outside 5-10% which had unrecoverable errors.
At that time, I remade the discs when I had added a new Pioneer BDR-205. This time I checked to ensure I created them with Verify and Defect Management on. I verified them with DiscSpeed and most were 100% 'Green' at that time.
But a year later and now many of these verify the first 90-95 percent as 'all green', but have yellow/red bad spots on the 'outside' scan again (and won't read completely without errors).
The discs get stored in white sleeve DVD cases in an dark environment that runs 55F - 70F. Much older DVDs I have seem fine.
Anyone have any ideas on what might be going wrong?
