Hi, this is Wayne again with a topic “Data Recovery As Fast As Possible”.
Data loss, no matter what you do, it can still happen, sometimes as it did to us when our main SSD server spectacularly went down. But you can check out in this article 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 the leading a file in Windows is only actually marking the data as free space. It just sits on your drive until something overrides 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 test disk, 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 that 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. That might look like something out of a movie about our 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 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 Derek’s boot and nuke before you sell your PC.
