I would like to know if a dvd rom over time could start acting up as far as reading disks? Sometimes the disc is scratched but does'nt look to bad but I get an error cyclyic redundency error. I have had this drd rom for about 3 yrs but wonder if over time they might not read as well as in the newer state. I have ran probably 700-800 disc through it. Any info would be appreciated.
