Arvind pointed me to this & I was amazed to know the fact. My DVDs and CDs are good for few years only
A quick googling gave me this...
>>You know those CD-R's and DVD-R's that you've trusted your most precious memories to? They could be little more use than coasters after just two years.
>> Typically, however, they will claim an estimated shelf life of between 5 and 10 years.
I don't want to believe this but at same time it might be true. Even we have seen CDs/DVDs going bad soon.
I've started backing up my stuff on my online... (Hope it will be fine there)
