[title] Parted Magic - Erasing hard drives | |
- | [* icon_caution] ***When possible, avoid sector-wiping SSDs. This will reduce the drive liftetime and can be drastic on older 75TBW SSDs.*** |
- | [* icon_caution] ***''Your erase options will be limited to the Security Set options supported in the drive firmware.''*** |
- | [* icon_reminder] Drives without ATA Secure Erase will need to be erased externally. Select ***''External''*** and choose Nwipe. ***''Run the DoD Short command (3 wipes+drive blanking).''*** |
- | [* red] ***''If your drive has a buggy ATA Secure Erase implementation, choose External and erase the drive with Nwipe.''*** ***''SSDs should only be erased with the Secure Erase command.''*** |
- | [* orange] ***''For NVMe SSDs, the best option is to use NVMe Secure Erase.''*** |
+ | [* icon_caution] ***When possible, avoid using "sector wipe" on SSDs. This will eat into the TBW of the drive, which can cause problems on older 75TBW drives.*** |
+ | [* icon_caution] ***The options available here that will work will vary based on what is supported by the firmware on the drive.*** |
+ | [* icon_caution] ***CAUTION: Drives with known issues in the firmware around the ATA Secure Erase option may be bricked depending on the severity (and risk). If you use this on a drive with known problems, it can potentially brick the drive. When in doubt, select EXTERNAL for safety (at the expense of time/NAND flash wear on SSDs).*** |
+ | [* icon_reminder] ***IF the drive does not support ATA Secure Erase (primarily older drives),*** you will need to select ***External*** and use Nwipe to erase it. ***The best middle ground in Nwipe/DBAN is "DoD Short (3 pass+blanking).*** |
+ | [* red] ***AHCI drives (M.2 SATA/2.5" drives/3.5" drives)*** When possible for security (and in the case of SSDs, reduced or mitigated drive wear), try to use the ***ATA Secure Erase*** option when possible, unless the drive has known bugs (see warning above). |
+ | [* orange] ***NVMe SSD Recomendation:*** When possible, use ***NVMe secure erase***. This is instant because it destroys the encryption key on these drives so the data can no longer be read and does not need to zero out the entire drive. |
