I’m not an expert, but wouldn’t proper deletion be writing random ones and zeroes to the block?
Comment on iPhone owners say the latest iOS update is resurfacing deleted nudes
Forester@yiffit.net 7 months agoProper deletion should include writing all 1s or all zeroes to the block but y’all be lazy as fuck.

I don’t think it’s been shown to make a difference.
EvilBit@lemmy.world 7 months ago
It certainly feels more deleted…

That just makes no sense to do, modern storage is write limited. As long as you used encryption the old bits mean nothing.
catloaf@lemm.ee 7 months ago
SSDs are. Big storage is not using SSDs.

yeah cuz for normal, day-to-day use that’s exponentially slower the more you’re deleting
You can do that when you wipe something.
Forester@yiffit.net 7 months ago
Yeah, such as sensitive photos

Nitpick: it should be fuzzed with random 0s and 1s.

Only necessary on the ol spinning rust, with SSDs not only is not completely unnecessary, but it also burns extra writes.
Spinny’s store data magnetically on the platter with 1s and 0s, SSDs store data on the NAND as a held charge. If there’s a charge in the block it’s a 1 if there’s no charge it’s a 0.
With spinny’s, a file gets marked as “deleted” but the residual magnetic 1s and 0s will remain on the platter until eventually overwritten
With SSDs a file gets marked “deleted” and within no more than a few minutes TRIM comes along and ensures the charge on the NAND is released for that data, there’s no residuals to worry about like with spinny’s and is in fact necessary to ensure decent lifespans.

I want a spinny as a pet now. Sounds cute.

But wouldn’t TRIM be the deleting he is requesting? Removing the charges would be setting all the bits in that block to the same value.
