We always care about the data and we always look out for the the ways to protect our data from loss. When ever we think of data we think of the hard drive and the flash drives that have our data but we kind of ignore the optical storage media that is the CD DVD. Most of us think that the data stored in the CD or DVD id really safe and we don't need to worry about it. It's not the case as we worry about the data in the hard drive similarly we need to worry about the data in the optical media too. It can't be left alone.
CD/DVD's are really sensitive, there are several reason that cause data loss
1)Dirty disk surface
2)Dirty lens in the DVD reader
3)Software or hard ware problems
We need to analyze the reason of the data loss before trying to opt for the data recovery
method. It will minimize the effort you will put in to check out every possible cause.
The recovery process is also not that simple as its in the hard drive corruption scenario. We need to consider too many things before taking the backup media into consideration.
Those points are:
Durability of the media : should be given the prime importance as if the durability of the media is low then the data is again at a danger of getting corrupt. The total mechanism might get destroyed which will lead to data loss.
Size of the media : has to be given the importance too as if it's bigger in the size then it can disturb the whole system. If the media is smaller in size then in that case it will capture only the data that will fit in and the rest of the data will be lost. Each and every computer has it's own configuration ans we must choose the media accordingly.
Lastly the media that is portable to the system should only be used. Even a tape can be used for CD DVD data recovery
it will read the data and create a copy with in itself.
