Hi DEP! Did you format your friend's HDD using -u option? Or was it a clean, low level format? I'm not sure if there are any advanced techniques of data recovery. You can try the data recovery software available for free in the following link
https://www.recovermyfiles.com/

It should recover all your lost files. Let us know your experience.

Hi DEP,

We find a no. of softwares available in the market which recovery the lost data's which have been deleted from hard disk. Some them available free of cost which are downloadable from internet.

You also check the range of Fastrecovery & Unistal.

in any case, if you are very persistent about recovering that data make sure you don't use that hard disk any more. You can decide wat recovery software to use later. but before that as a precaution stop using that hard disk. There's a chance that it could be over written.

Don't you think your vernacular post will make it difficult for our International audience to understand what you are saying?

DEP, I guess the software should be able to recover the data if the format was 'Quick Format'. As Desijays said, stop using the HDD, otherwise the data will get overwritten. Just let us know the results.

its supposed to be be "if someone" !!!! duh.

i think you should go through the common sense guide

Good Luck mate

ps: i have a feeling i'm breaking some of the rules this very moment. And i have a feeling atkt knows !!

How if every engineer over here starts posting in his/her own language? We'll have to wait till he/she explains the same again in English.

That's against Common Sense 😁 . CEans are supposed to follow the Common Sense Guide, that's the only expectation over here.

Let's stick to the topic.

hi desijays $ big_k,

thanks for the suggestions. i am not using that hardisk at all. i am going to try out my hand on those recovering softwares in a day or two and will surely tell you the results.

I have recently lost my windows data from my hard.My hard drive get corrupted.I do not know what to do.I have search on net data recovery software and found list of software.I have tried Stellar Phoenix data recovery software.Firstly I download the demo version and see preview of most of my data.Then I download the full version and recover all my data.This software is very good. If any one is in trouble and want good data recovery try this software from
Hard Drive Data Recovery Software, Disk Recovery & Data Recovery Tools - Stellar
Hope it will help you to recover your data back easily.

Hi to all, anybody know how the data ll occupy the space in HDD?? let me explain...as yo all know data stores in consecutive bytes and the particular data is read from its index address. whenever yo try to read some data then the control signal ll send the index address to processor and reads the data( its lengthy process).As once you delete any data from HDD then the control signal ll just send the index address of particular data to processor then the processor ll jsut delete the index address but not the whole data, so according to my knowledge i'm suggestin yo that yo can definately recover ur lost datas unless n untill yo dint FORMAT the HDD. Once you do format then plzzzz just forget the thing what you want to recover....

hi all
you can recover data(most of not all) even if you have formatted you hdd using some data recovery tools, but only if you have not stored any new data on the formatted disk.
some people are Professional data recovery specialists.

Hi,
I would like to add some info that I googled to this interesting topic:

There are 2 kinds of formatting methods avail:
1. High level format (also known as quick format)
Only rewrites the File Index(Master boot record, File Allocation Table, Master File Table) of the media and makes the whole space available for writing data. Althought physically, previous data is still present, only marked as free space.
Data is almost fully recoverable.

2. Disk Reinitialization (also known as Low level format / Default Format)
Every sector of the drive is written to by writing a zero byte to every addressable location on the disk.

Recovering overwritten data
When data has been physically overwritten on a hard disk it is generally assumed that the previous data is no longer possible to recover. In 1996, Peter Gutmann, a respected computer scientist, presented a paper that suggested overwritten data could be recovered through the use of Scanning transmission electron microscopy.[3] In 2001, he presented another paper on a similar topic.[4] Substantial criticism has followed, primarily dealing with the lack of any concrete examples of significant amounts of overwritten data being recovered.[5][6] To guard against this type of data recovery, he and Colin Plumb designed the Gutmann method, which is used by several disk scrubbing software packages.

Although Gutmann's theory may not be wrong, there's no practical evidence that overwritten data can be recovered. Moreover, there are good reasons to think that it cannot.[7][8]

Feasibility of recovering overwritten data
Peter Gutmann investigated data recovery from nominally overwritten media in the mid-1990s. He suggested magnetic force microscopy may be able to recover such data, and developed specific patterns, for specific drive technologies, designed to counter such.[1] These patterns have come to be known as the Gutmann method.

Daniel Feenberg, an economist at the private National Bureau of Economic Research, claims that the chances of overwritten data being recovered from a modern hard drive amount to "urban legend".[2]
"Surveying all the references, I conclude that Gutmann's claim belongs in the category of urban legend.
Or it may be in the category of marketing hype. I note that it is being used to sell a software package called "The Annililator". "

As of Nov 2007, the DoD considers overwriting acceptable for clearing magnetic media, but not as a sanitization method. Only degaussing or physical destruction is acceptable for the latter.[3]

On the other hand, according to the 2006 NIST Special Publication 800-88 (p. 7): "Studies have shown that most of today’s media can be effectively cleared by one overwrite" and "for ATA disk drives manufactured after 2001 (over 15 GB) the terms clearing and purging have converged."[4]

Personally, I think it's not totally impossible to recover data "bit" by 'bit", as data is a sequence of "1 and 0 bits" (8 bit being 1 byte).
But it would be extremely COSTLY, requiring a high level of forensic expertise in a "clean room" and plenty of patience. Thus, nearly an impossible task to undertake.

If u have used quick format then you can recover data using tools like 'get data back' or 'easy recovery'.There are many tools available but i think these two are better

Yeah definately it is possible..........Deleteing the files or data only deletes the reference to them. The files are still on the hard drive until they are overwritten......
There are programs or softwares that will find these deleted data.....Advanced disc recovery is a type of application which is used to recover lost data...it can also recover data from formatted hard disc ....
