About SSD Memory Cell Clearing
The page describes how to reset a solid-state drive to its factory clean state using firmware-level Secure Erase, which can restore factory default write performance. It covers SATA ATA SECURITY ERASE UNIT and ENHANCED SECURITY ERASE UNIT with hdparm, including checking for frozen security state, setting a temporary user password, and issuing the erase command.
It warns the procedure destroys all data beyond recovery and requires repartitioning and restoring data afterward, and must only be used on drives directly connected via SATA/NVMe. Secure Erase does not reset cell wear-leveling status.
Key features
- Instructions for ATA SECURITY ERASE UNIT and ENHANCED SECURITY ERASE UNIT
- Commands to check if drive security is frozen
- Steps to set temporary user password with hdparm
- Workarounds for frozen state on Dell systems
- Guidance to verify correct device node before erasing
- Advice to check logical sector size after clearing
Best for: People maintaining Arch Linux systems who need to clear a directly connected SATA SSD.
Good for
- Explains restoration to factory default write performance
- Lists hdparm commands to check status and issue erase
- Notes the same ATA commands can zero out hard disk drives
Watch out for
- Erases all data beyond recovery and requires repartitioning and restore
- Requires direct SATA/NVMe connection; USB or SAS/RAID use may brick drive

SSD Memory Cell Clearing FAQ
Does Secure Erase reset SSD wear leveling?
No. A drive close to the end of its lifespan may become writable for a short while, but it will still fail after a limited amount of writes.
Does TRIM prevent all write-performance degradation?
No. TRIM only safeguards against file deletes, not replacements such as an incremental save.
Can I run Secure Erase over USB?
No. Do not proceed unless the drive is directly connected to a SATA/NVMe interface; using USB or a SAS/RAID card could potentially brick the drive.
