No matter what you do, it can still happen sometimes as it did to us when our main SSD server spectacularly went down, which you can check out in this video up here. But, we were able to get back up and running thanks to our friends at We Recover Data who worked with us on this episode, which is sponsored by them. So, data loss is a little like the sword of Damocles, constantly hanging over the head of anyone who stores anything important electronically. But, after it happens, is it really gone for good? Often, the answer isn't clear. What if you delete a file by mistake, suffer corruption due to power loss, or have physical damage like a head crash where the read-write head of your hard drive crashes into the platters that store your data? Fortunately, there's a number of techniques that have been developed over the years to rescue inaccessible data before it becomes permanently lost. Let's say that you've been the victim of the all too common accident where someone empties your recycling bin, and it turns out that you had a mission critical selfie inside of it. Since deleting a file in Windows is only actually marking the data as free space, it just sits on your drive until something overwrites it. So, sooner is better if you're using simple recovery software, lest your selfie get overwritten by something completely irrelevant like a tax return. But, what if you can't even access your drive due to some type of serious corruption with the file system itself? In that case, certain utilities like open source TestDisk can attempt to repair the underlying problem with the drive. But, if that works, you could attempt a file technique called file carving, which despite its name is the process of reassembling files from fragments by looking at their headers to try and figure out what kinds of files they were, whether they were MP3s, JPEGs, or whatever else. But, if you have a hard drive with a platter that just won't spin, or maybe bad sectors, or a bad PCB, or an SSD module that somehow came loose, you'll probably want to send it off to a data recovery specialist as they have the correct hardware to physically examine the disk. If you don't have that, you're putting your hardware at risk, which is putting your files at risk, which is probably not a great idea. In the case of a hard drive, it'll need to go to a clean room that might look like something out of a movie about a killer virus since any type of dust or particulate can potentially wreck that part of the data on the hard drive or platter beyond recovery. Some drives can be rebuilt with new components, while other drives have to be examined by special machines that can read data directly off of platters. Pretty cool. Of course, however, even with the most advanced recovery methods, you can't get all of your stuff back in every case. This can be for reasons ranging from physical damage that's too extensive to having proprietary storage medium that needs to be reverse engineered to the target data being overwritten before you can recover it. It's virtually impossible to recover overwritten data using current methods, which is why it's a great idea to intentionally overwrite your hard drive with something like DBAN, also known as Darik's Boot and Nuke, before you sell your PC.
