When purchasing or replacing a computer, questions about the Hard Drive Wipe procedure are frequently posed. The process of erasing or removing your personal information is surprisingly straightforward. To completely erase your data, you will need to overwrite it. Simply reformatting the hard drive or deleting all of the files will not be effective. A number of inexpensive and free wipe programs, also known as shedders, can obfuscate the data with a random pattern or zeros, rendering the data restoration software unreadable. However, there are machines capable of recovering data that has been overwritten a few times. This is where the secure erase standards, such as DoD 5220.22-M, will need to be referenced. According to the specifications, it would be challenging to recover the data if the drive were overwritten three times. However, a number of experts recommend that you overwrite the data seven times to ensure that you have completely erased it from your hard drive, rendering it unrecoverable. Sometimes reading data that has been overwritten by a shredder requires expensive hardware, so if you are not concerned about professional data theft, you do not need to overwrite sensitive information.
Always keep in mind that deleting your sensitive files or data will not provide you with complete protection. This is due to the fact that there may be unidentified copies of your file or data in an unused portion of your swap files or on your hard drive, as well as other possible locations. You can err on the side of caution by erasing an entire section of your hard drive, or you can be certain by erasing the entire hard drive. There are a number of software programs that can help you delete specific files and the free space on your hard drive, as well as software that will overwrite your hard drive three times.
If you wish to dispose of your old hard drive or sell your old computer, it is imperative that you take the utmost care in erasing all of your personal and sensitive files and data prior to selling your hard drive. Although it is extremely challenging to recover lost data from any hard drive, it is not impossible. However, data is recoverable to some extent. If proper specifications are followed, this task can be made impossible. Always keep in mind that deleting files or data or formatting your hard drive alone is not enough to completely erase your hard drive. To ensure that your fines have been completely erased, you should utilize an erasing or wiping service. There are tools available to help you clear your hard drive, which will overwrite every sector. Before selling your hard drive or computer, one of the most important things you must remember is to empty or otherwise prepare your hard drive.
