![]() ![]() Multiple overwrites is completely pointless, except in as much as it may result in all viable sectors being recycled at least once. ![]() Previous existing data will remain in sectors awaiting recycling, and if the drive has detected that any are giving soft errors above a certain threshold they will be permanently left in a pool of worn sectors. If you write to every addressable sector, it’ll simply allocate new sectors for the zeros you’re writing - but the drive’s garbage collection will already have cleared them. It’s important to note, though, that it’s not possible to reliably wipe an SSD. It doesn’t connect to the Internet (or any network) so its attack surface is essentially zero. Apart from that I wouldn’t worry about lack of updates. Maybe DBAN no longer boots easily under UEFI. I’ve used DBAN and nwipe a fair few times but ShredOS is new to me. Can you explain please? DBAN, nwipe and ShredOS all use essentially the same code to do the wiping, with (as far as I can make out) pretty much identical user interface. You say “by its nature” DBAN won’t work on SSDs. ![]()
