Keep your fingers crossed.

I've had serious trouble with a whole bunch of CDRs containing my
back-ups of film scan data. They were stored in specially made CD paper
jackets, the kind commonly used in books or commercial software
packages. These jackets, bought from a local CD production company, had
self-adhesive flaps and it appears something evaporating from this
adhesive has damaged the CDs in the jacket to the point that they've
become unredable. All this after about four years of storage. There was
a distinct brownish colouring of the CDs in the section whch had been
next to the flap.


I've had a few CDs go bad, stored in plastic jewel cases. I've always tried to 
buy name brand 
ones such as Verbatim or Fuji, and I have always verified the data after the 
write. It's just 
the luck of the draw, I guess.
I'm pretty close to buying an external RAID of some sort, and I will probably 
transfer as many 
of my files over to it from the CDs as is practical.
