Erasing Hard Drive Completely
Our hard drives contain all types of information related to us, like credit card numbers, detailed personal information, financial information, medical reports, e-mails and lots more what we go on storing on them, these information's and data are still their on the hard disk even after we delete, erase or just format it and at any moment it can recovered using right recovery software's.
May a times we just delete the data or just format the disk before dumping your old disk thinking that the data is lost forever but it isn't the truth if the drive hasn't been erased completely anyone can recover the data which was present on your disk and can misuse it, so be cautious before completely dumping your old hard disk.
Now how to be on the safer side..?
Many of use will think that reformatting will do the trick but its not secure, we have to do disk wiping. Disk wiping is the method through which we can ensure that data is irrecoverably deleted before dumping the storage device. Disk wiping is a process in which it will overwrite entire hard disk with data several times and then it will have to be formatted which will make it impossible to retrieve data which was stored in disk.
There are lots of products available which can perform disk wipes, these disk wipe applications typically overwrite the master boot record, partition table and every sector of the hard drive.
Few of the applications available:
WipeDrive and MediaWiper
Paragon Disk Wiper
