Hard drive making strange noises is one of the most common types of hard drive failures. At times it can be much more severe than what you can imagine. Now follow the steps introduced in this article to protect the data on the failing drive.
When you hear strange noises from hard drive, no matter clicking or whirring sounds, it usually indicates that some components of the drive are damaged physically. Hence, you should take immediate actions to increase the chances of successful data recovery. Here are some essential steps if you notice odd sounds from an internal or external hard drive.
1. Shut down the Hard Drive Immediately
The case that hard drive makes grinding sounds usually occurs from mechanical failures. On average, it is either the drive heads or motor spindle malfunction. Here we will take the issues in drive heads as an example. The drive heads play an important role in reading and writing data on the platters that store the data. If the heads are damaged, they will get direct contact with the drive platters. At this point, the drive’s magnetic coating would be scraped during its operations. Apparently, this will lead to serious data loss immediately.
Under this circumstance, the longer the drive works after mechanical failures, the more extreme the corruption of the drive platter and the more severe data loss. Therefore, you have to shut down your drive as soon as you’ve heard any unusual grinding sounds from the drive.
2. Don’t Reboot the Hard Drive to Access Data
If the hard drive makes unusual noises when booting, everyone will absolutely worry about their data stored on the drive. For laymen, they will boot the drive, trying to access the data and verify its integrity. In fact, it is utterly wrong.
In light of the same principle, when you attempt to access your data, the heads will continue to read data. There is no denying that it will destroy all the exact data tracks and sectors where the data that you are accessing is located. Also, your original data may get overwritten. All these issues will greatly decrease the chances of data recovery. No matter hard drive makes clicking, grinding or whirring sounds, you should never try to reboot the drive to access your data
3. Don’t Utilize Recovery Software
As we all know, a great deal of DIY recovery software is available in the market nowadays. However, in prior to purchasing and putting the software into practice, we had better to consider a question. That is “What happened to your data on the hard drive?”
If your data is just deleted accidentally or just corrupted due to logical errors, you can apply the DIY recovery software to retrieve it. For example, if you cannot open your PST file in that errors occur to the file, you can use a PST repair tool to recover it. In contrast, if data got damaged owing to physical damages, don’t resort to DIY software. In this scenario, data recovery software will do nothing but to make the situation worse.
4. Bring the Hard Drive to Data Recovery Professionals
Now that your hard drive is damaged physically, the best way to protect and get back the internal data is to contact data recovery professionals for assistance. You should never take a chance to open and fix the drive by yourself, which will reduce the odds of data recovery to zero.
