In general, however, data recovery software is safe and can be a helpful tool if you've lost important files with intuitive graphic user interface. However, it's essential to be careful when using these programs, as they can sometimes cause more damage to your device. If you're unsure whether it's safe to use data recovery software, it's always best to consult with a professional.
Data recovery software is a program that can be used to recover lost or deleted files from your computer. When a file is deleted, the data is not actually erased from your hard drive. Instead, the file space occupied is simply marked as empty and available for new data. As long as the old data is not overwritten, it can be recovered using special software. Data recovery tools work by scanning your hard drive for any traces of the lost data. Once they have located the data, they can then rebuild the files and save them to a new location. In most cases, data recovery software can successfully recover lost files with little to no damage. However, if the data has been overwritten, it will be much more difficult to recover.
The source and destination drives must be different. When recovering from the operating system drive (often C: ), use the /n switches to specify the user files or folder.
Microsoft automatically creates a recovery folder for you called, Recovery_ on the destination drive.
When you are prompted for confirmation to continue, enter Y to start the recovery operation. Depending on the size of your source drive, this may take a while. To stop the recovery process, press Ctrl + C.
There are several file systems supported by Windows that vary depending on the storage device or operating system. Recovering files from non-NTFS file systems is only supported by extensive mode. To see which file system you have, right click a drive in File Explorer and select Properties.
To keep your results manageable and focus on user files, some file types are filtered by default, but this switch removes that filter. For a complete list of these file types, see the information after this table.
Behind the scenes, Windows is constantly creating and deleting files. By default, Windows File Recovery filters out these files, but some slip through. To prevent this, use the /n as per examples in this article.
For NTFS and segment modes, you may also see lost files recovered from the Recycle Bin (files either in the recycle bin or that were permanently deleted) with the name $files.xxx and stored in a folder called $RECYCLE.BIN.

Scans for files with specific file types. Separate multiple entries by using commas. For a list of extension groups and corresponding file types, see the table, "Signature mode extension groups and file types" in the section, "About modes and file systems".

The former kind look at the file-system on the disk for information about files and folders to recover. They may look at the FAT/MFT, but usually when a file is lost, that information is lost and so these programs will often examine the clusters on the disk to find what look like directories. Then they will examine the directory entries to identify files that are marked as deleted. If the indicated files have not been overwritten, then there should be enough data in the directory (name, starting cluster, and size) to recover the file. The same goes for subdirectories: there should be enough information (name, starting cluster) to identify the subdirectory and repeat the aforementioned process for files in there.
The latter type of data-recovery program ignores the file-system altogether and instead looks for file types. It will usually contain a list of file signatures (e.g., headers, magic numbers, etc.) which are typical of different kinds of files. It then scans the disk, looking for these patterns of bytes, and whenever it finds one, it adds that cluster, and a number of subsequent clusters as a file, then displays the list of files.
The two methods have their pros and cons, and which you use is up to you because it will depend on your disk and files. You are probably best served by using at least one program of each type to maximize your success. That way, you will find the most files by recovering both the most content and meta-data (filenames, etc.) You may need to do some comparisons and manual work to copy the correct meta-data to the correct content, but it is your best bet at maximum recovery. On the down-side, using multiple programs will result in a lot of clutter and false-positives that need to be sorted through, so it is up to you to decide the value of the lost files.
I understand the 'source' for the names is the Master File Table where it stores names/structures/attributes etc. Is this true? For true recovery, with structure and names, is it necessary to have the MFT intact?
Recovering deleted files is often more successful with NTFS than with FAT for the reasons you described, however PhotoRec is a signature-style program, so it does not refer to the MFT for meta-data about files/folders.
Depending on the file system, the name and the contents of the file are usually stored in different places. The name and timestamp will go in the directory with a link to a separate series of blocks containing the contents of the file. When a file is deleted, the blocks holding the content are returned to free space and the directory is edited to remove the entry. Undelete programs can spot the blocks that were recently freed but the directory entry will already be gone. Again, the specifics depends on the OS and the filesystem but I hope this gives you a helpful, but general idea.
Due to some problems, I tried installing Ubuntu in my machine. But accidentally I installed it in the same partition where my earlier installation was. My data was inside the home directory in the same partition. So all got wiped.Is there any way to recover the data? I am trying to use Testdisk. It is analyzing the disk for several hours. I am not sure how to use it properly. Is it the right tool? Or should I try any other tool?
TestDisk is a much better tool than PhotoRec. However, the only problem with TestDisk is that it doesn't always recover all the deleted files. So, if you accidentally reformat a partition, TestDisk can recover thousands of files without missing a single file, but if you deleted a file by sending it to the Recycle Bin (Trash), and then emptying the Trash, TestDisk might not be able to recover it for you in all the cases.
PhotoRec can selectively recover files based on their filetype(s), but PhotoRec / TestDisk can't selectively scan an individual directory for lost files unless you had mounted a whole hard drive partition as this directory. In some cases, the filename is stored in the file itself. PhotoRec tries to recover the filename in this case, but most of the time PhotoRec can't recover the filenames.
I have deleted a zip archive from my E: drive which was really important to me about 3 days ago.Since I really needed it back, I ended up using Data Recovery software like eraseus data recover. This software showing me a lot of files that I can recover, but almost all of them are really old (months old, or some of them are years old), and wouldn't even show a file that I have recently deleted even if i try a deep scan.Can anyone please explain me why I cannot recover recently deleted file ?
A file you deleted 3 days ago, you would expect to be easier to recover. However, depending on where on the drive it was saved, it may have already been written over. A file that was deleted months ago could be closer to the end of the drive, and not in imminent danger of being fully erased from the drive itself.
That said, it might be worth trying different recovery software, as the detection may vary between different packages, avoiding writing anything else to the drive until you've fully exhausted the options.
To some extent, the longer a deleted file sits, the more likely it is to be overwritten or otherwise irretrievably lost. So the percentage chance an older files can be recovered is lower than for more recently-deleted files.
Say you have 10 recently-deleted files and 5,000 files not recently deleted. Even if 20% of your recently-deleted files and only 2% of your older files are recoverable, that will still mean only about 2 recently-deleted files and about 100 files not recently deleted.
Whoever said that lied to you. Unless you had /home on a separate partition, and in the new install chose to not format that partition, your files are unrecoverably gone. And even if /home was separate, if it was encrypted I hope you backed up the encryption key. Otherwise the files are still gone.
On re-installing Ubuntu use option "Upgrade" to not wipe all home directories. You may then have created a new account rather than using the existing one. In case your file system was not encrypted your data may still be present in the home directory of your previous user. To test this open Nautilus and point it to "File System -> /home. See what directories are there.
