Reclaim your DVDs.

Many times we face a very common yet unrecoverable problem and that problem is read error or CRC error while reading a DVD. 

Today I will show you different methods of overcoming this problem.

 First of all if you are installing from the DVD or playing directly from DVD then don’t do that. Copy it to your local hard drive. And eventually you will get the error message while copying from normal Window copy pest. You must use Tera copy (click on the link to download) or similar software which can error freely copy from a DVD.

The other thing that you can do yet the risky one is to clean you DVD read write side (i.e the glossy side which you are told not to touch) some time when a DVD is left for a long time due to moisture the glossy side becomes opaque due to dust deposition. Hence laser can not read correctly. So follow these steps.

1. Spray Collin or other cleaner that is used to clean tables or TV screen.(i.e used to clean glass) on the glossy side.

2. Leave it for a second and the rub the glossy side with cotton, rub it until all the Collin is dry.

3. DVD is ready for use.

Nokia 808 PureView 41 mega pixel Camera

Cant believe your own eyes?well, guess what i didn't too and lost bet with one of my dearest friend.But it is true, Nokia has announced a phone that will come with an 41 MP camera.They announced it at MWC 2012 and named it 808 PureView.

The technology means that taking typically sized shots (say, 5 megapixels) the camera can use oversampling to combine up to seven pixels into one “pure” pixel, eliminating the visual noise found on other mobile phone cameras. On top of that, you can zoom in up to 3X without losing any of the details in your shot – and there’s no artificially created pixels in your picture, either.

                                     some says that it will be available in india for Rs.30,000/-
