(1) In this lesson, you learn the essentials of file recovery in the three major operating systems. Discuss how to recover information from damaged media. Also, tell us your experience how to recover files from a crashed hard disk or a bad memory card.

Deleting a file is a common way to remove pieces of evidence from the source. Criminals would think that after deleting the file from the drive would create a safe environment for them. There are the different system for a different version to store the data such as FAT16 and FAT32 used in pre-Windows 2000 versions, NTFS file system in use since Windows 2000. Also, each of these systems has its own algorithm to store its data.

There are numerous ways to undelete or recover hidden or deleted files. One of the most common ways to undelete a file is “Winundelete” which is a very easy process. It is done through the wizard-driven. The next tool which can be used to undelete the file is “FreeUndelete”. This is for personal use. Deleted data unintentionally is a distressing encounter that influences many people who carry on with the computerized way of life. There are a few situations where you may erase records or void your PC reuse canister unintentionally. Typically, you can lose information because of physical harm done to your hard drive or through a sensible data loss process. Most physical harm situations are irreversible and might require proficient assistance from hard drive recuperation administration. Nonetheless, data damage situations that are not brought about by physical harm can be effectively recovered with hard drive information recuperation programming. Sensible information loss includes documents that have been lost because of arranged hard drive or unplanned erasure. The best alternative to regain the hard drive after physical harm is to open and assess it, supplanting any part that is harmed. The information from the hard disk, for example, hard disk, CD, DVD, floppy are replicated to some solid medium which is otherwise called test system. The replicated information is a unique copy of the information on the capacity media, keeping up a comparative structure. This is not as simple as a copy-paste but needs to be created using a special software program. Recovering from logical damage is quite challenging. According to the article (Recovering Data From Damaged Media, 2018), a special software are required to recover logically deleted files. Some of the tools for Microsoft windows is chkdsk, linux is fsck and Mac Os is disk utility.

One time I accidentally lost my data which was very important for my science project while I was in college. I permanently deleted the file from the recycle bin. Then I used ApowerRecover to get it back. Also, one of my memory card was crashed and I was not able to locate my file. I used disk drill to get it back.
