With technological advancement at its crest, new devices are launched every other day that are equipped with much better security and other features. Because of this reason, users are often making the shift from their old devices to the new ones. As you make the transition to a new device, it is really important that you take care of your personal data that was stored in your old device.
Formatting and deleting is ineffective
Many people believe that formatting or deleting the files from the media is the best way to wipe away all important data. This is certainly not true. This data still exists even after the files have been deleted or one has executed the format command. A delete command merely removes the pointers to files that make it impossible for the OS to locate the data. The data remains in the device till the time it has been overwritten with some new data.
This is where data recovery techniques come into play. By using specific tools and skills, data recovery in Brimingham can be done by scouting for data that exists on the drive and offer several options to recover them. There are many data recovery products available in the market that anyone with wrong intention can get and access your personal files if you have not cleaned the device thoroughly.
Here are simple ways how you can erase data from your device effectively:
Simple yet effective data erasure techniques
You would be surprised to know that data can be recovered from damaged hard drives as well. Therefore, just to be sure that your sensitive data does not get into wrong hands, you must know how to destroy it completely before you discard your device.
• Physical destruction of your device
This is the best and the easiest method to ensure that your device won’t be used in future for extracting any information. You may break the device apart or shred it into small pieces. Once the device is physically destroyed, no one can recover the data from it. The best part about this technique is that you can destroy a large amount of data in one go easily and can be used for any kind of media.
There are a few drawbacks of this technique as well. Firstly, it lets the user destroy the device and not the data. Once the hard drives or media are destroyed, you will not be able to sell it to get any compensation.
• Magnetic destruction of the recorded data
This process is known as degaussing and it involves applying a reverse magnetic field with a machine. Once the magnetic flux returns to a zero state, all content on magnetic media is erased. However, you must remember that different magnetic media needs different magnetic field strength. Therefore, if you fail to create a strong magnetic field for a particular media type, the process would remain incomplete. This process is quite effective for deleting data that requires low electromagnetic field and is less time consuming as well.
There are some drawbacks associated with this technique. First, you would need to invest in a degaussing machine and it does not assure that it would produce strong enough fields to destroy data on several types of media. The machine is quite expensive and not everyone can afford it. Furthermore, this technique is only viable for magnetic media.
• Software overwrite
Special software is used for overwriting existing data with some patterns of meaningless data. This is done several times on each sector of the hard drive to ensure that all current data has been overwritten and is beyond recovery now. The more times the data is overwritten, the higher would be its security.
Well, it does not matter which technique you use. After all, you just have to ensure that your data cannot be recovered from your old device!
