    Default Erasing Hard Drive Completely

    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

    Permanent Erasure

    DBAN

    Eraser

    Best way is to destroy. That is what is being done in US intelligence agencies.

    When you format, only the indexes will be erased, But all the files will be there in the hard disk. As long as, the memory locations are not overwritten, the files can be recovered if you can guess the index(starting point) of that file. That is what a recovery tool does. What a Wiper/ Eraser/ Shredder does is, it overwrites the memory locations with some random values. So, even though you know the exact index of the file, all you can recover is some garbage values.

    One can shred the hard disk, just by overwriting the previous files which can be done by pasting some other file in the exact same folder of the previous files.

    While there are a lot of hard disk eraser's on the market, the only way to permanently delete a file is to overwrite it with another.

    Blank overwriting as far as I'm aware is the only way to securely delete anything on a hard drive and only that will stop the original file from being able to be accessible later on.

    That is quite a lot of things to learn here. I know the files once deleted will remain in our hard drive for some more time until it is overwritten by another file. So, I think till then it is recoverable under any circumstances, right? Hope this applies to mobile phones too or any other devices that use memory to store files.

    So, it is better to take out the memory card when you give your mobile phone for repairing or something like that. Will that be enough to protect our private data in mobiles?
