How to recover data from formatted c Drive

[ramji]

I have lost most of my photos that i kept in the digital camera and laptop.

my laptop did not boot up on one day , i kept all the photos in it .the laptop service guy formatted it and all my data in that were erased.also he loaded the new OS in the c drive , can my pics taken from this?

the photos in my digital camera got deleted ( the photos taken before a period of time ) due to some unknown reason and i bought Vibosoft for the data recovery for 2000 rs and it recovered a part of the deleted photos.But the i could see the actual count of photos as 2500 and around 600 was shown as corrupted .
can the corrupted files recovered back ?

I have earlier uploaded my pics in picasa but deleted after some time can those be recovered some how?

Kindly suggest me a good idea , i need those pics back some how.

new OS overwrote data, overwritten data area permanent loss. only hope to get the rest area data.

use the drive as secondary, thn run the soft, also recover data to another location except original partition/c drive.

thanks man can you say the most powerful recovery software , the softwares that i have used so far scans some 7 % of the c drive then the system hangs , any idea why this happens

Considering them both together, the 2 parts I have underlined suggest that your drive has an internal fault - likely having problems reading some sectors and it might get worse if you continue trying to recover directly from that drive.

Do you want to continue with DIY recovery attempts, which means that you accept responsibility for the possibility of losing your data permanently due to any mistakes that you make (or just bad luck) with your recovery attempts?

If you accept responsibility for continuing your DIY attempts, then a typical next step would be to clone the full raw drive (or at least the relevant partition) from your "problem" (source) drive, onto another (target) drive with enough free space [which you need to provide / buy], using a utility which is designed to cope with and retry/ignore unreadable blocks, and preferably not running on Windows e.g. DMDE, GNU ddrescue, Prosoft Media Tools Pro etc etc. If you clone the drive (or partition) to another drive/partition, you will lose all data on the equivalent part of the target drive. Alternatively you can (try to) create an image file of the "problem" drive, into a filesystem on the target drive. Make sure you understand the difference between these 2 techniques!

There are several places where you can make a mistake, if you are not experienced. This approach has been discussed here many times - search the forum for discussions about cloning. However, based on your comments and the fact that you used a "laptop service guy", I suspect that you should not attempt this yourself due to lack of experience, and should instead seek professional help. In your case, from the symptoms you have described, it is not just as simple as running recovery software on your drive.
