| 1454314 | 2018-10-10 23:55:00 | Does anyone have any recommendations on tools to wipe an SSD before selling it on Trade Me? I'd like to avoid wearing it out too much before it leaves my hands, so don't want to be a tool designed for hard drives in mind. I just want to make data recovery on it difficult, it doesn't need to be military grade or anything :) | pcuser42 (130) | ||
| 1454315 | 2018-10-11 00:19:00 | It's not a good idea to do a secure erase since this means it'll do multiple writes lowering the SSD's life. Maybe just a single write with random data be enough but involves creating a lot of entrophies or just fill it with zeroes. If on Linux, using dd would be enough. |

| 1454316 | 2018-10-11 00:20:00 | Its an SSD , so multiple passes wont do anything more than a single pass will. anything with a single pass wipe would do the trick windlg : write zeros (WD's tool) I think CCleaner has a tool for HD wipe from memory ? Some drives even had a built in wipe command, I havnt used that for many years though or DBAN dban.org diskpart : clean. Given how fast the clean command is, I wouldnt rely on it for a secure erase |

| 1454317 | 2018-10-11 00:29:00 | This is new information :-) so the correct answer is smash it with a hammer or take the risk "With Solid State Drives, the disk erasing utility does not have direct access to the sectors on the drive. There is therefore no way to guarantee that a command to erase a given sector will actually erase that sector. The SSD’s controller may instead remap that physical sector to a new logical sector, leaving the data intact but inaccessible. Even a full overwrite of a SSD may therefore not result in a fully wiped drive. However, the data remaining on the drive would not be accessible via normal means. Recovering such data would require removing the actual flash chips from the SSD’s circuit board and accessing them with special equipment and software tools." www.cru-inc.com |

| 1454318 | 2018-10-11 01:12:00 | I guess I'm just less worried than others. I just delete the partitions and create new ones or simply reformat the drive. Data recovery may still be possible but not by most people, assuming whoever buys it even tries. | dugimodo (138) | ||
| 1454319 | 2018-10-11 01:38:00 | It depends what was on it . If there has to be zero chance of recovering old data, then physicaly destroy the HD Otherwise, as duji's suggestion . Format & write heaps of stuff onto it, format again :-) |

| 1454320 | 2018-10-11 01:48:00 | SeniorNet recommends DBan for us oldies. We burnt it CD for some unknown reason. lurking. |

Format & write heaps of stuff onto it, format again :-) Since that's technically already been done as the SSD was briefly repurposed, I'll just take the diskpart clean route :) |
