Physical Hard Disk Destruction Methods and the Benefits

خرید دی وی دی خام However, if the thief is desperate, he can use advanced tools to get to the permanently deleted file.What actually happens when a file Is deletedWhen a file is fully deleted, they are not actually overwritten. Nevertheless, it is rare to see such a file being reused and, it only occurs when a disk space is required.There is a different file removal method for each file system type. Below are some common files systems and what it does when a file is deleted.NTFS: When there is nothing written in the disk, after deleting the file, the data are intact.FAT: The information about where the file fragment is lost immediately. If the file is not fragmented, then you can recover the file in full. The more you change things, the more you add files, the more the disk becomes fragmented.

HFS and HFS+: HFS stores information in a balanced tree structure. Sometimes, when a file is deleted, the entire tree has to be re-balanced resulting in massive change to the file system's structure. Using the tree method in the file system, recovering is unpredictable, and it all depends on how you tried to recover the file.The only way to make the file unrecoverable is to use software meant to overwrite bits of data in a file. This method won't work at all times specially when the hard drive is beyond functional state. Another procedure of data destruction is to destroy the HDD itself. Below are some drive destruction methods and where these methods are effective.Hard disk shredderWhen we shred paper, we know that our sensitive cannot be recovered any longer because we know nobody can bring a shredded documents back particularly if the shredded paper is extremely thin. That same convenience can be done on HDDs too, only that these are shredders are meant to shred metals as if it were paper.Advantage Increased data security. A shredded disk cannot be patched up and be functional again. Reduce the risk of improperly discarded drives. Minimize storage cost. However, the cost of buying a shredder is truly expensive and, hard disk destruction services are costly too. Hard disk shredders are also bulky in size you will need a specified room for hard disk shredding because not only that it is bulky but; also hard disk shredders are unusually noisy.Hard Disk CrusherA device meant to crush the hard disk by putting a large amount of weight into the drive.Advantage Small and compact. It can be used even in a desktop. Silent. The process takes less than 10 seconds. Platters are bent. It create ripples that even a hardware recovery method is impossible. A quick solution to destroying the hard disk data but not the problem is how you will dispose the crushed drives. Hard disk degausserA hard disk destruction machine that has a tremendously powerful magnet in which it can alter the current state of the drive, removing any residual data and also making the drive utterly unusable. Older drives won't get affected by degaussing but modern drives will become inoperable since modern drives have servo tracks inside the platter that can be erased the same way data in the disk are erased.
