If you want to keep/sell the drive...
Is that the best strategy? Or is anything outside of 2 and 3 redundant?
You can’t fill the drive. The drive decides when to use its buffered free storage blocks. It’s at the hardware level and only the Secure Erase command will clear it.
Right, I read some more of the comments and realized that's what some of the "unreported space" is used for. Makes sense, thanks!
You fill up the usable space. Or the visible space. No one will disamble the device and read from the raw storage.
Then why do that when you can do a secure erase in seconds?
That makes sense. Thank you!
Nobody is gonna bother doing advanced forensics on 2nd hand storage, digging into megabytes of reallocated sectors on the off chance they to find something financially exploitable. That's a level of paranoia no data supports.
My example applies to storage devices which don't default to encryption (most non-OS external storage). It's analogous to changing your existing encrypted disks password to a random-ass unrecoverable throwaway.
