As P.F.R. above says, CDs are a very long way from permanent. I have professionally recorded CDs that are showing signs of deterioration, and some self-burned CDs that are unplayable. Not just MY self-burned CDs.
A couple of bright spots. I had occasion to burn an LP copy recently, and I found that 'LP Recorder' freeware still works on this W7 machine, although my old Nero software (for W98) doesn't.
Also, I needed a new cartridge for my turntable and found 'L.P.Gear' in the USA could supply one that may well be better than the old one was when it was new.
What a trip down memory lane this thread is. I feel like drinking to absent(web)friends.
