Can the ZimaBoard 282 power 1x 3.5 inch Hard Drives? and Disk Wiping Tool for CasaOS Help!

[sinful tusk]

you simply can do
dd if=/dev/zero of=/dev/sdX status=progress to overwrite an attached HDD fully with zeros

Doing this over e.g a docker container is a little complicated because docker cannot access the full block device

thanks a lot, so i guess after writing zero, do you think other disk recover software like Easus recover will recover the data?

[sinful tusk]

no. once you overwrite sectors with 0 there are zeros

you cannot magically recover the state it had before.

thanks a lot

[sinful tusk]

you can use /dev/urandom

to use random numbers as your source

then it just a random mess

but a little slower

[versed hamlet]

great, thanks a lot

[sinful tusk]

there are also other command line utils like with gui. etc. https://www.maketecheasier.com/completely-wipe-hard-drive-linux/

i don't know a docker container for this, but you might be able to forward a full disk into the container

To quote this "PS: Before you Bruce Schneier fanboys downvote me: I want proof that it's possible to recover data from a non-ancient rotational hard drive that has been overwritten with zeros. Don't even think about commenting otherwise! :P"
