Erasing SSD's and NVME's #156
-
|
Hello, I was wondering which method Shredos uses, especially for Sata/M2 SSDs and NVME SSD. Is Sherdos just filling all the blocks on the disks, so Shredos doesn't recognize the difference between disks? Or my understanding is incorrect. Thanks :) |

ATA secure erase is scheduled for release 0.35 or 0.36. So at the moment it simply treats a SSD or NVME as if they were an ordinary spinning disc, ie just filling all the blocks. You can do a ATA secure erase using hdparm or nvme-cli by running the commands in the ALT F2 virtual terminal in ShredOS. In the 0.35/0.36 release there will be a new method 'ATA Secure erase (HDD/SSD/NvMe)' built into the nwipe GUI that issues the ATA secure erase command and lets drive do the wipe. nwipe will estimate the progress on screen so it will look similar to wiping a HDD. |

Is this still being worked on? Can we expect it in future releases? |

That's the plan. Unfortunately I'm really busy on things unrelated to ShredOS/Nwipe at the moment, so no timeline. |

Hello, thanks for the response. Is there any expected release date for 0.35/0.36 or for nvme-cli/hdparm (or maybe month, year, etc)? Or it is just planned for the future? |

I'm currently finishing off the PDF report and will more than likely do a 0.35 release next week or the week after. I will then do a full release of ShredOS based on the 0.35 version of ShredOS, that will be the week after. ATA secure erase will be done immediately after that. I've given myself a couple of months, but may do it quicker.. but as soon as ATA secure erase is complete I would release as 0.36. So probably two months between the two releases. So i guess I'm looking at sometime in September .. fingers crossed for ATA secure erase... famous last words :-) |

Okay thanks, that's a pity but I will be looking forward to it ⏩
Are you thinking, that it will be just an option in GUI to select the deletion method? Or some automation, because it would be beautiful to just connect all disks to the computer running shredos, the system will recognize them and delete them accordingly by their type. (HDD, SATA SSD, NVME) I'm thinking something like this script for Parted can maybe be an inspiration: https://github.com/tslight/disknukem |

Yes, that's certainly a possibility, i.e in config there could be an option Always wipe SSD/NvMe with ATA secure erase If that is set then only connected HDD's will be wiped with the selected method, while the SSD/NvMe drives will be wiped with secure erase. |

Thanks for that link. It's always useful to see how others do it. I could always include those scripts in shredos if anybody is interested. |

Maybe this could serve as a temporary solution until you develop something robust and you will be satisfied with it.
But it would be very useful |
