Has been recovering a lot of old photos from 2 HDD's. 99% of my 100+ Gb is in perfect shape so now I decided I'll store this on Blu Ray disks. I use Verbatim discs and ImgBurn software on an Asus BW-16D1HT burner. But when the disk is finished and I try opening photos, then a lot of files just don't work. Some of them are totaly dead, others gets read like half of the picture, the rest is in one collor only. What can be the problem?
