    Best way to wipe data partition on SSD?


    My 2Tb SSD is failing and I have a Dell guy coming on Monday to replace it.

    I have a data partition which is all fully backed up and in dropbox but I want to securely delete all the data on this partition, and probably some of the files on the Win10 partition too.

    Searching mainly seems to come up with options for wiping the whole disk, which I don't want to do. I also found a few commenst that wiping an SSD is different from wiping a HDD. How so?

    Any recommendations for a free utility I can use?

    I'm running Win10 Version 21H2 (Build 19044.1826) if that makes a difference.

    Cheers

    You could use something like Diskpart, or extend the OS Partition after formatting the Data Partition, or use something like . . .

    Thanks @Paulblack

    Even if I delete the partition and extend the win10 partition does that not still leave the original data potentially recoverable? I'd always assumed unless you overwrote the disk with 1/0 then you hadn't truly "deleted" everything.

    If I was replacing the SSD myself I woudn't be concerned as I would retain the disk and then wipe/delete in my own time but Dell will take the old SSD away with them and it contains a lot of proprietary and confidential data from my work.

    I wonder if you delete all the files and folders from the partition and then run trim.

    It erases the data blocks that are not in use.

    If you rt clcik a file and delete, it can still be recovered.

    If you run trim those blocks are erased.

    Looks like Minitools Partition Magic might be what I need as it will do a secure delete of a single partition using it's "wipe" function.

    I guess I could move any other files on the OS partition onto my data partition and then wipe it in one go

    those kind of things write 0 and 1 to all the sectors sometimes using several passes. You wouldnt normally want to do that on an ssd.

    If it is failing anyway, I dont suppose it matters.

    there are special tools to sanitize ( some call it secure wipe ) an ssd without causing all the damage of multiple sector overwrites, but I think they do the entire disk - it only take a couple of seconds

    you could move any data you need off it first, then sanitize.

    All the usual ssd toolbxes have that sanitize function - corsair ssd toolbox, samsung magician, the crucial storage executive, the micron one and so on.
    The Secure Wipe tool will completely and permanently erase the entire drive contents including partitions and file systems returning it to a raw state. Any data that was previously on the SSD drive will be non-recoverable at the end of this process
    If none of those support your ssd, there is one in partedmagic that works on all of them as far as I know.

    Partition assistant i recommend. you can scrub as many passes you want too deeper and deeper and also replace all sectors with all 0's or 1's it will take time to scrub deep and then run replace with 0 1's

    if any program is fast its just doing a basic format. recoverable. !!!

    Hi,

    The SSD manufacturer's management app is the first place to check for a secure erase tool.

    Using the "ATA Secure Erase" command instructs the drive to flush all stored electrons, a process that forces the drive to "forget" all stored data. The command resets all available blocks to the "erase" state and runs trim on the whole drive.

    There is no wiping of the drive done and there's no recoverable data left on the drive after it's done.
