Windows 10: How dangerous is erasing/wiping an SSD while it's still running with the OS running?

Oh yeah I have Windows 11 "How dangerous is erasing/wiping an SSD while it's still running with the OS running and its the OS thats erasing it?"

Securely erasing old SSD - Ubuntu

Very inexperienced with Linux and have been playing around lately with Ubuntu 17.10 successfully recovering data from a bad HDD, quite impressed by it also.

First question is. I have an old OCZ Vertex 3 120GB that has been lying around forever and want to wipe it to factory settings and install Ubuntu on it (so I don't need to run Windows side by side on my current OS drive). I'm assuming the easiest way to do this is to do the following?

• Boot Ubuntu from USB installer
• Select 'Try Ubuntu before you install it'
• Open the Terminal and
• Use the Command-line to Simple Secure Erase i.e. hdparm --security-erase PASS /dev/sdX

My second question is, if the above will work do I then need to format the entire SSD in ext4 or does the installer by default format/partition the SSD when 'Erase disk and install Ubuntu' is selected?

 

Completely wipe an SSD including Windows 10

If I plug the SSD into my new PC, will the 2 versions of Windows 10 on each of them clash and cause an issue?

- Nope.

And once I put the SSD into my new PC, how would I go about completely wiping its contents and Windows 10 off of it?

- Open File Explorer and go to the "This PC" section

- Right-click the drive you want to erase and choose "Format" in the list

- Use the default settings and just click OK to format (erase) the drive

 

How to securely erase an SSD using the OS on the SSD?

Does anybody know of a way to erase hard drives from the hard drive? Without anything else?
EG. I have a windows 10 pc and would like to wipe the hard drive as-is, with no boot key/disk and while running either the OS on the HDD or BIOS?
