I have to reformat my hard disk, 500 Gb.,due to "error finding your system's active partition". I went through Google and found Easus which wipes and formats. I checked other sites too like killdisk, dban and other sites. One thing struck me is all these sites announce complete wiping to erase data so that you can discard or give it away or resell the same. I wish to reuse the same disk. Can I reuse it, without any tension after I wipe? If so, will someone please guide me how? Thanks in advance.
