Unexpectedly, anyone lost his/her files from Android phone or PC etc then immediately they might get a doubt how to recover deleted files from external hard drive?. In this case, everyone follows a different procedure. But choosing the right tool will certainly recover the lost files. Anyhow, I hope you’re the luckiest person for choosing our platform to get back your deleted files and surely this article will help you a lot.  Simply go through DiskDigger Pro.

What is DiskDigger? And How DiskDigger works?

DiskDigger is a free data recovery software which helps to recover lost files, photos from your memory card and or internal memory without rooting process.

How DiskDigger Works? 

DiskDigger has two methods which you have to choose every time while scanning a disk. These methods are named as “dig deep” and “dig deeper“.

Now Let’s See How Diskdigger Works: 

Digging Deep: 

The “Dig Deep” advice DiskDiggerundelete” files from the file system on your disk. Suppose, under many file system, when you delete a file, it doesn’t get wiped from the disk. However, the file system will simply mark the deleted file and will not display you the file when you browse the contents of the disk. DiskDigger scans the file system for deleted files, display them to you, and allow you to bring them back as normal files again.

To implement this process we have several limitations. First step1: Diskdigger has to be “aware” of which type of file system present in the disk. To get knowledge of those files follows the below steps.

FAT — Used on floppy disks (FAT12), most USB flash drives and memory cards under 4 gigabytes, and older hard disks (FAT16).
FAT32 — Used on slightly older hard disks and most USB flash drives and memory cards with 4 gigabytes or greater.
NTFS — Used on most modern hard disks.
exFAT — Used on some modern hard disks and high-capacity memory cards and USB drives.

Luckily, the above list of file systems covers the wide majority of the world’s users, so this limitation is trivial compared to the next one.

After a file deleted, the file system is completely free to overwrite the contents of the deleted file with new data. From the perspective of the file system, the deleted file is currently as good as free space, prepared for the taking. The following file that is saved by the file system may simply be written on top of the deleted one. If it happens,  the deleted record will really be lost forever.

So, the rule would be like this: The undelete procedure is effective only for the file that has been removed very recently. Or on the other hand, more exactly: The likelihood of effectively retrieving a file is inversely corresponding to the amount of time passed in the wake of deleting it.

Digging deeper:

The “dig deeper” mode causes DiskDigger Pro became a  powerful information carver, and carve out whatever file it can discover on the disk, free of the record framework. Information cutting alludes to physically scanning each and every area on the disk, and searching for hints of known file types.

Pros And Cons:

This method has some pros and cons. The main pro is that it’s independent of the file system that’s on the disk, so the disk can be formatted as FAT, NTFS, HFS, ext2, or anything else; it doesn’t matter. DiskDigger scans “underneath” the file system, which gives it an added pro of being able to scan any free space on the disk outside of the file system, which the “dig deep” mode cannot do.

The main con of digging deeper is, it takes more time for scanning. If you’re scanning a memory card or USB drive, it shouldn’t be too bad, but if you’re scanning an entire hard drive, be prepared for a several-hour job.  Of course, the burden of the time spent on the scan is subjective and depends on the value of the files you’re trying to recover.

And one more con of this method is only a limited number of file types can be recovered. Since we’re not aware of the file system, we have no way of knowing what types of files are present, so the only thing we have to go on are the actual bytes that we see on the disk. This means DiskDigger must know about the structure of the file type we have to recover lost files and search for examples of bytes explicit to each file format. Luckily, DiskDigger supports a genuinely wide variety of document types which should cover most cases.

Last but not least, one more con of this process is that it’s not possible to recover files that have been fragmented by the file system.  Since it’s not aware of the file system, DiskDigger has no way of knowing whether or not a certain file has been fragmented. So, technically, when digging deeper, DiskDigger will just recover the main fragment of a file. Most files comprise of a single fragment anyway, but in some cases, the file system will choose to split a file into two or more fragments. A standard guideline is:  the bigger file is, the more likely it is that it’s been fragmented. I hope data recovery software helps you a lot.
