Slowness and blue screen If you are noticing and exaggerated slowness, your machine is crashing a lot, see if your computer or laptop is too hot too. This happens because his parts can't find the required data easily, and they keep looking and looking, it takes time and effort (which turns hot). Make a backup as soon as possible and see below for tips on trying to save your hard drive. Files are not opening Maybe the problem is with your Windows, but until then its worth check-in if it's not with your HD. Let's repeat one more time: make a backup. Also, make a loop antivirus scan after the backup. Many times this kind of error is not related to the physical structure of the hard drive (less bad, right?). If you don't find any virus, you can format your hard drive, then its code will be "redone". If none of this solves, you will have to buy a new HD. When this kind of error starts to happen, the tendency is only to get worse. It may be just that song, that photo, but soon less will be more and more important files. That is, take action as soon as possible. Corrupted files Several and several files are showing the message that they were corrupted? This is worrying. We recommend that you do the same procedures as the previous topic: backup, antivirus scanning, and formatting. If you use the hard drive again and the files are still corrupted, it is likely that it has bad blocks. Bad blocks Bad Block is a physical problem and when the first one shows up, he will call his bad blocks friends and they will become a gang. Then more and more bad blocks will appear and you will not be able to use your HD. You must identify where these errors are (you can use this program) to isolate them and not use these parts of your hard drive anymore. After doing this, make a backup (the backup is after isolating the bad blocks, remember that) and run to buy another hard drive. Strange sounds They may look like aliens trying to communicate, but they are just the parts of your HD asking for help. Unfortunately, the limit of use has arrived. These noises can be either the HD itself, the parts giving trouble, or your computer for not being able to interact with it. The needle may be out of position, some components may be defective, or the motor may be stuck. It varies a lot, but both the sound coming from the HD and from your machine are worrying situations. If you still can, backup your data immediately and buy another HD. It's worth remembering that needle failures are extremely worrying situations. The longer it takes to solve this problem or change HDDs, the more data will be affected.
