Celsius Posted May 31, 2023 Share Posted May 31, 2023 Yes. I used dban 20 years ago and it is still as effective. Just put it on usb and launch it before starting winblows. I do not see how can anything be recobered after overwriting it with a bunch of 1 and 0's 2 Link to comment Share on other sites More sharing options...

JustAnotherHun Posted May 31, 2023 Share Posted May 31, 2023 If you hand your old PC to others, use Eraser https://eraser.heidi.ie Even IF data could be restored, it would be very very hard. So If your data is not relevant to NSA, you schould be very safe. If you want to throw it away, damage the HDD physicly. 2 Link to comment Share on other sites More sharing options...

The abovementioned Darik's software has got that covered.... "There's a popular freeware app called DBAN (Darik's Boot and Nuke) that writes to all the sectors using secure sanitization methods." "Select the method of drive erasure by hitting M if you want something other than the default, DoD Short method. DoD short is a 3-pass version of the American Depart of Defense 5220.22-M wipe process. It overwrites all sectors with zeroes on the first pass, overwrites them with ones on the second pass and then uses a random pattern on the third pass. A standard DoD 5220.22-M erasure is 7 passes. The more passes, the longer the secure erase takes. The DoD short method should be fine for most people so you can skip this step if you agree."

clearance Posted May 31, 2023 Share Posted May 31, 2023 There is another way: Encrypt drives with Bitlocker with a strong password (no need to save it obviously), format drives after that, and write some big files to them (you can use CrystalDiskMark with larger file sizes possible). Almost impossible to recover any data after that. Link to comment Share on other sites More sharing options...
Lemsta69 Posted May 31, 2023 Share Posted May 31, 2023 Just for laughs, why not try the Peter Guttman method? 35 passes with random data, not ones and zeroes.

bendejo Posted May 31, 2023 Share Posted May 31, 2023 Another vote for Darik's. I used it and then had a look at the disk. It shreds the partition table into a load of tiny partitions. It appeared that the entire disk was filled with partition table data, over-writing just about all of whatever was on there before. Haven't used it in some years, and it appears it hasn't been updated in a while. https://www.lifewire.com/dban-dariks-boot-and-nuke-review-2619130 The newer versions of Windows create private partitions to hold Win data, which is why the partition table needs to be destroyed for cleanup. If you want to fix the partition table afterward (as a courtesy to to whoever you're giving the system to) use a Linux installable booted from a pen drive or CD. There is a bootable Linux utility called gparted that I prefer -- easy to use. If you want to be a rascal after the destruction is done fill the disk up with useless junk. If you suspect someone will attempt to recover what is on the disk that junk will keep them busy. ???? 1 Link to comment Share on other sites More sharing options...

Surface deleting files on a PC doesn't really erase them permanently. It merely changing the file info on the files so they're not readable by Windows... But that process can be undone by anyone with a bit of PC smarts, if they wanted to do so. Unless you physically disable the disk as suggested above, or really do a full and complete reformat of the disk. It all depends on where you toss them.

Any Thai computer shop I tried to hand them off to (even though they're still functional)...would probably laugh and hand them right back to me! ???? Not necessarily as old functional computer components can be valuable and sought after by some people. The last one I handed over was a 2009 Compaq laptop and they greatfully accepted it. Your 20+ year old systems might have some value yet. If they don't want it, dump it in the bin. Link to comment Share on other sites More sharing options...
