| Post subject: | SSD eraser question |
Hi I have got a work of secure eraser work of 100 odd ssd's Unlike CMR hard disks there is no chances of remnant data recovery on defect lists with SSD. I would like to know is it technically ok to single pass overwrite., so that I can quote for the same. Thank you. |

Single pass overwrite potentially leaves you with overprovisioned space. Writing zeros potentially leaves you with lots of unaffected data due to advanced firmware detecting zeros and simply add place-holders in FTL. Zero filling overwriting virtually nothing due to firmware level compression. Why not use built-in secure erase, crypto erase etc.? |

Thanks a lot Joep Do I need third party tools or manufacturer utility to initiate secure eraser. Cusomer wants reports of each eraser like model, fw, sn, erasing date / time Technique used and time required etc. |

Maybe a tool like KillDisk will make your life easier but I personally believe your client wants to purchase peace of mind with that certificate. |

Exactly ,even client suggested this. Is there any universal secure /crypto erase tool irrespective of make of SSD ? For large volume of disks its not practical to check each ssd & erase it using manufacturer supplied tools (not all tools are self bootable as well) Thanks |

IIRC, the ATA standard has sanitize and cryptoerase commands. These are universal, ie not vendor specific. |

Thanks a lot fzabkar , I have used killdisk as I think its too clumsy to boot large (different types ) of laptops using linux & issue commands onsite. There should be a readymade live bootable pen drive having interface , logging to perform the same. Besides that I read that not all models support secure erase. |

Well, Older versions of killdisk was able to work with several hard drives without a license |
