CD-RW 24x disc read problem

Hi, folks,

I’d like to ask You about one strange problem. I wrote two CD-RWs 24x two years ago. Recently I tried to read them with my pc, but they didn’t start and these inserted discs appear as “blank”. Do CD-RW 24x discs become unreadable after more than two years? These two discs were stored in dark cool place all the time.

Thank You,
