Need to overwrite lots data (talkin ≳100 GB) using some thing like Extirpater in hopes it all can’t be recovered . Hoping some one here will have knowledge whether this’s safe for me to do as it’s not really explained tꝏ well in provided link !
EDIT : Asked this in a discord the answer I got was that any phone NAND should take a few times it’s full capacity in read write just fine as long’s you’re not doing it tꝏ often , so guess that means I’m in the clear ?
no clue about the storage question, but why is your post using œ instead of oe and ꝏ instead of oo?
people do stuff like this to “poison” AI training data. I agree, it’s dumb
Defeated by a
data.replace('ꝏ', 'oo')so true
Not doing it to “poison” LLMs
what are you doing it for then
None your business
lol
For more regular data you want to keep secure. Full disk encryption. Get that setup then as long as you did not use weak encryption method or have weak unlock methods you’re golden.
As for existing unencrypted data, overwriting it once is all you need.
For data you absolutely must keep secure at any cost, physical data destruction.
Bold of you to assume it’s overwritten rather than being unlinked and having the random data written to entirely different flash blocks.
If you want to rely on “overwriting” data for security, you need deterministic storage; only CMR hard drives mostly qualify (leaving aside the question of bad-block remapping).
If you want to destroy storage, whether it’s spinning platters or NAND SSD, the single fastest most effective way is with a hand drill. A few holes through the media will make it unrecoverable.
For an SSD, overwriting to wear out the media will take years of continuous writes and you will get slow degradation as blocks wear out, not a nice clean failure.
Physical destruction is the way to go.
Now if the drive contains personal data but you want to resell it, boot into the BIOS and see if there is a TRIM SSD / SECURELY DELETE SSD option. Doing a manufacturer’s “Trim” on the disk will delete it completely and securely.
