Parted Magic - Erasing hard drives

  • 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.

  • The options available here that will work will vary based on what is supported by the firmware on the drive.

  • 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).

  • 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).

  • 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).

  • 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.

(Parted Magic) Effacement des disques durs

Dans la mesure du possible, évitez d'effacer les secteurs des SSD. Cela réduira la durée de vie du disque et peut être drastique sur les anciens disques à durée de vie de 75 TBW.

Vos options d'effacement sont limitées aux options de jeu de sécurité prises en charge par votre lecteur.

Les disques sans ATA Secure Erase devront être effacés en externe. Sélectionnez Externe et choisissez Nwipe. Exécutez la commande DoD Short (3 wipes + drive blanking).

Si votre disque a une implémentation buggy ATA Secure Erase, choisissez Externe et effacez le disque avec Nwipe. Les SSD ne doivent être effacés qu'avec la commande Secure Erase.

Pour les SSD NVMe, la meilleure option consiste à utiliser NVMe Secure Erase.
