Disposing of deleted data.
To save using free-space wipers, can I just do an
intelligent image backup to another HDD, reformat the original HDD and then restore the image back to this? Is there a facility in the .cmd to wipe clean a drive beyond forensic access? Peter |

I downloaded it and tried the 64 version, but I get a flash across the screen and nothing else. I found this in my sysinternals folder too, but this gave the same results. I have Win10pro. |

Reformatting doesn't wipe the "deleted" data. A utility like Recuva can recover it. the only suer way to remove data from a HD is to destroy the platter. Is there a facility in the .cmd to wipe clean a drive beyond forensic access? No. But there are utilities that will do this. They overwrite the disk several times. "Forensic access" is a variable, however. For most purposes, 7 or so overwrites are enough. For most purposes, doing nothing beyond deleting the files is enough. But if you really want to prevent access, destroy the platters. Which will destroy the HDD. Yes. But that's enormous overkill for almost everyone. |

But if you really want to prevent access, destroy the platters. Which will destroy the HDD. Yes. But that's enormous overkill for almost everyone. yep. |

So unnecessary. diskpart list disk select disk 3 list partition # verify you're on the correct disk clean all # *zeroes* every byte of the hard drive # This can take hours. Pack a picnic lunch. exit Now, take HxD the hex editor, and skim through the disk, and verify that the disk is indeed empty. ******* You can also use a utility that does Secure Erase or Enhanced Secure Erase, which are features of the ATA command set (good for IDE or SATA drives, but not SCSI). In those cases, the drive erases itself, and that takes hours too. Paul |

On the contrary, it makes things simpler. What apparently the OP wants is to delete permanently whatever he deletes, and for this he is prepared to copy everything to another disk, format fully, and restore the data. This process takes many hours. And would have to be repeated often, as soon as he does some work with that sensitive material. With full disk encryption you simply do nothing. You do not need to destroy erased data, as it is not accessible being encrypted. Fast and neat, and works every day, instantly. Someone steals the machine, the data is safe. The paranoid would worry whether full disk encryption in Windows is reliable, and thus prefer secure deletion. -- Cheers, Carlos. |

He needs to erase the drive everytime he works on that sensitive material. He dis not say anything about giving the drive, he is keeping it. So everytime he works on the data, he needs to erase it. Or, encrypt it instead. Just once. -- Cheers, Carlos. |
