subject: Can I Do Data Recovery For My Deleted Or Corrupted Files After Running Defragmentation? [print this page] Given the plethora of questions about the recovery of deleted files (which I shall call Undelete), I would do a story that explains why we do not recover all the deleted files and that the defragment regularly brings in that context.
I must save my recovered file on another physical disk or logical after data recovery.
This is because a deleted file is not really what are the areas it occupied that are made available. If one wants to retrieve a deleted file, you are strongly advised to write to another medium, same logic, so as not to overwrite areas of the file. That is to say that if you have 2 drives (C and D) but are actually a single physical disk, you can save on a file deleted D on C, and vice versa.
I often see people asking how to retrieve a file or data recovery from corrupted disk , they are not ad hoc program. In this case, we must take all precautions. For those who surf to find an Undelete program, which the download on the same disc, there is very little chance that they recover their files. Ideally, it should already have the program Undelete hand. If this is not the case but you have a 2nd PC with Internet access, please use this one to download the program Undelete and set it on a floppy disk.
If you're networking, you may be able to recover a deleted file on another PC (I have never tried but a priori, it should work). If you only have one PC with Internet access, then download the file to a floppy or other disk that you want to retrieve the file. Be careful when installing, it could crush the areas you want to just recover. There Undelete programs that do not require installation, I think especially Restoration can run from a floppy disk, it needs only 400 KB when unzipped and no d ' installation.
Now when we run defragmentation in out computer, it collects the unused spaces from the sectors of the hard disk and assign this collected space as free for storage. Now it starts data gathering at one place starting from the first place and overwrites all free space by the data and assign the new empty space as free to data storage.
Now if we have some deleted files or corrupted files, and need to recover them after the defragmentation process, now it is not possible to recover these because the spaces have been overwritten.
