What is the Purpose of a Hard Drive Shredder?
As a paper shredder is needed in order to destroy or remove any documents on your paper, a hard drive shredder is also needed in order to completely destroy or remove any documents on your hard drive. The main purpose is to completely destroy all the files as well as not to leave any trace of the shredded documents in the history or directory of your computer. Deleting a file in your computer does not mean that it is completely removed from your hard drive. A person having the right knowledge and expertise can easily find the location and recover the deleted file. But in some instance, a deleted file may also be removed from your hard drive if it has been written over with other files that will usually happen after a long period of time. But you cannot be sure, since a deleted file can still be recovered if it is written over only once.
Primarily, what a hard drive shredder does is to overwrite the file in order to completely remove it. In case where the files needed to be removed is very sensitive or confidential, you can also overwrite it several times. The same process of overwriting is again used in order to remove any trace to the directory after deleting it. Shredding an entire partition of a hard drive is useful and highly advisable if the file that you want to remove has been edited several times. As well as to shred the entire partition, if the file you wanted to remove has been previously moved. If the purpose of removing the files is for security reason, then it is highly advisable that you shred the entire drive. In can be difficult to use a shredder if the drive containing the confidential information has been defragmented. Since the partition containing the files may be marked as a bad sector, and cannot anymore be visible to the computer. It would reveal, that on most computers that were donate, files containing personal information can still be found even if they were already deleted. That is why if you have any sensitive or personal information that was stored on your computer, you need to have hard drive shredder before you can dispose of it. This can be very useful if you belong to a company who is going to make an upgrade on their computer and would want to donate or sell the old ones. This is the case where a hard drive shredder is usually needed in order to protect confidential information. Because the information that are stored on your computer is mostly related to your work or company. Then it would be better to use a hard drive shredder to be sure that files containing any confidential information are completely removed than to normally just delete the file.
