in situations when I need to sanitize a few laptops, I get annoyed by having e.g. 4 laptops running 24/7 just to have 'shred' running and cloning the image. So I got myself an external HDD to USB adapter to be able to just shred and supply HDDs from my normal private laptop and install them in the sanitized laptops afterwards.
Here is the adapter I bought: https://www.pearl.de/a-PX4943-1162.shtml
Problem: I used a Tails Linux installation booted from USB stick and command 'shred' to shred a HDD connected by mentioned adapter. Always after a few minutes, I got an 'I/O write' error and shredding failed.
I tried another borrowed adapter and the same approach worked, but the shredding was much slower than during the few minutes when it did not yet fail with my adapter. The only difference I saw was the working adapter had only USB2, while mine had USB3.
So my questions to you people come done to this:
- How do you kill the data on laptops for sanitizing?
- Do you leave the HDDs inside the laptops or do you use some adapter, like I tried?
- Do you use command 'shred'? If yes, how many rounds? If no, what tool do you recommend?
- Any recommendations around my 'I/O write' error?
