5 Things You Can Do to Securely Erase Your Hard Drive
For those who recently upgraded to a new laptop, the need to wipe your old hard drive correctly is vital. Not many people know that simply deleting data is not actually getting rid of it. When data is deleted, it is hidden from plain sight, but it is still present in your computer. In order to really delete data from your desktop, more invasive steps need to be taken. IT outsourcing services are ideal if the data erasure is being done by a business on more than a couple computers. Data that falls into the wrong hands can affect business continuity, or worse, cause a breach. It is therefore imperative to ensure that an IT consulting service provider is engaged in this process.
Data backup should be done before beginning the cleaning up to avoid permanently losing any important data. After the files are erased, they cannot be retrieved. Cloud archiving is an ideal, safe and convenient method to backup. Follow the steps below to make data permanently unusable:
One option that can be used is encryption. This method of securing a hard drive is popular, but can be time consuming. If the erasure is being done by your IT department it may not be the best use of resources. For those who use cloud computing, encryption is much less tasking and can easily be completed by a qualified IT consulting company.
There are software utilities that wipe out data safely. These utilities have specifics on the number of passes to make. Every pass indicates that the data is completely overwritten. A utility that conducts three passes therefore means that the data is overwritten three times. The more data is overwritten, the harder it will be to recover. There are utilities which can sustain Gutmann protection levels and perform 35 passes. However; three passes is what high security units such as the military and U.S defense department use. It can therefore be ideal for most businesses.
3. Open Source Eraser
This tool can be used to select the specific folders and files. To use this method, simply boot up the computer program and click on the arrow that is in between ‘erase schedule’ and the ‘’settings tab’. Select ‘new task’. A window showing the options for time schedules and tasks will pop up. Choose ‘add data’ then select the folders and files you want to erase and a method to erase. The DoD option with three passes is enough to completely erase your data.
Eraser has various options for those who need to regularly erase files safely. It however only works on HDD and not on SSD.
4. Roadkil Disk Wipe
Roadkil Disk Wipe works great on flash drives and hard drives too. Once a complete download is carried out, simply choose the drive to delete and key in the number of passes. One can decide to fill the file with junk or just wipe it clean.
DBAN works on SSDs and is loved by IT consulting experts. To access it, download and burn it onto a CD, then boot it to the computer. Once it is running in its blue and white signature page, choose the disk that needs to be cleaned and select the ideal erasure method. This method is time consuming. The amount of time it takes will depend on the disk size and erasure method.
For those who do not want to conduct erasure on their own, technical consulting services are a cost-effective and secure solution. iCorps Technologies provides IT consulting to Boston and companies in the greater Massachusetts area.
