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 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 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 after all who knows what the next owner might find hiding inside lynda.com with a lynda.com membership you can watch and learn from top experts we're passionate about what they're talking about what they're teaching you can screen thousands of video courses on demand and learn on your own schedule at your own pace you can browse each course transcript to follow along so if you missed the part you can find it in the text-based script and then go to that part of the video which is pretty cool you can take notes and refer them later on for specific videos you can download tutorials watch them on the go whether you're waiting in line somewhere or it's sitting in traffic maybe not a grater if you're the passenger sitting in traffic you can watch it on your mobile devices and you can even customize your learning path and share it with friends colleagues team members whatever your lynda.com membership will give you unlimited access to training on hundreds of topics all for a flat rate just starting at $25 a month whether you're looking to become an industry expert you're passionate about some random hobby or you just want to learn something new check out lynda.com slash tech quickie and sign up for your free 10-day trial alright guys hopefully that was great liked the video if you liked it you can also dislike it if you disliked it if you disliked it though I want you to go down into the comments tell me what you'd prefer me to cover that would be cool all I want to know what you want to see check my channel super fun if that's what you want to see and if you liked it and if you liked that get subscribed to both wine
