Help..How can I recover lost information after formatting HD ? Is it possible by Data Recovery Tools .?
Answers:
While all of those are moral PRACTICAL solutions to the problem, I think we'd be missing out if we didn't mention an implausible intangible model.
It requires access to an electron microscope, and probably friends at the NSA ... but it is theoretically possible to read the bits rotten of the disk based on minute traces by the read/write manager not doing a perfect duty of re-aligning ferrous material on the platters.
A fellow name Peter Gutman wrote a paper roughly speaking such a system in the precipitate 90's:

you need a second strong drive to put the files on, and a live cd with photorec. I've used it in the past and I've found tons of stuff
If your using the hard drive, be advise that any new information will start to overwrite the data your trying to recover. So first stop using that Hard Drive, next use a recovery tool like 'Recover My Files', cooperation to demo version http://www.tucows.com/preview/258313
Well so far in that are a lot of biddable things posted here for this but they are all incomplete, here is the in one piece thing......
Was the format a low height format
(kinda difficultly done)?
If it was merely a format with the format command dash or windows... be it a quick format or a full format?
If it be a low level format (usually done by a tech. to get hold of all virus off the drive or to fix doomed to failure spots on it) then the information is lost.
if it be a command line or window format, first, if it was a sudden format, all the information is still in that as long as you haven't used the drive to store anything since the format, if you did use the drive since the format some of the information is gone but most will be recoverable. However you will need a program to recover it.
the differences are.....
a low rank format will erase the whole drive and write the hex number FF contained by all the available space and to smudge the bad spots so they are never used (all drives will enjoy some bad spots) making it impossable to recover the information.
on a command smudge or windows expeditious format the only entry that gets erased is the FAT or NTSF this is the drives directory and wallet location information that points the computer to the place the files are stored but it leaves the information alone and most of it can be recovered. If it is a full command or windows format later the above is done plus the fragmentation table is also erased, meaning if a wallet was stored on the disk surrounded by two or more locations, when you recover the files that have be in fragments on the disk instead of a single recovered profile you will get two or more files that contain parts of the report that would require you to go threw them and see if you can put "humpty dumpty" rear legs together again, but are still recoverable but it is just profoundly harder to put things back together.
This is not a really glib process so ask your self if the information you need to recover is worth the time and try, but if the information is extremely valuable even if the drive have been low stratum formated there is a spirit of the information that can be recovered but a service need to do it and even later you will only attain an average of 35% ot what was lost and this is really expensive.
I hope this helps
The unadulterated trick to recovering the hard drive successfully is to realize how the file system works, you can any search the web for this information or you can email me for the information.
possibly... if you have not written up to date data to the drive (as contained by not even putting the operating system back) then Norton Utilities might know how to "unformat" the drive and recover ALL of the data.
The more you enjoy done since the format... the less facts you can recover.
If you used a "wipe" program... give up immediately. it will be gone.
yes i believe it is possible. I will ask my husband when he gets rear legs, so check he post later.
