#22See also [1], for a description of why erasing flash memory can't be done reliably with just "dd". Also, I find it disappointing that the GNU "shred" utility [2] apparently does not work as expected. [1] http://www.noah.org/wiki/Dd_-_Destroyer_of_Disks#caveat_on_F...

I feel stupid now. I can't be the only one who used shred on a journaled FS without giving it some thought.
It goes against unix philosophy of a simple tool that only does what it is supposed to do, but some warning from shred that you are using it on FS on which it can't be trusted would be nice.

#23I'm constantly amazed at the waste that happens when people decide they are going to destroy an old (serviceable) hard drive because they want to protect their old data on it. I don't see a need in 99% of cases, when there are perfectly good ways to permanently delete the data and make it unrecoverable, albeit taking a longer time. No doubt I'll get shot to bits for this with various edge cases where it's important t…
I agree Unless you're dealing with top-secret material, losing the encryption key is the best way Or just dd around 5x - 50x (or more if you're paranoid) its size to the disk - if you want to further reuse it. No, you won't have a meaningful amount of data remaining on the disk and extracting it requires special software/hardware. Unless you're dealing with data that makes the disk price irrelevant, you can follow th…
dd 1x-2x is enough in most use cases. most people don't have the time to go rummaging through random hard drive to recover what is mostly garbage. there might be a gem in there, but it's a straw in a haystack.

A bitcoin wallet is not top-secret material and I don't trust myself not to fuck up overwriting the entire disk. I'd rather just take an angle grinder to it and not worry about it.

#25Worst case scenario microwave it. It should make the ssd non functional and fry all circuits inside.
Re: How to securely recycle or dispose of your SSD
#26writing random data on it, rather than zeroing it out, will avoid block de-duplication and successfully completely fill it up. Here is a tool written for exactly that (although not intended for securely erasing a drive, it will have that effect too): https://github.com/rentzsch/stressdrive

#27I got only 3 words on how to dispose of your SDD:

ps: I am not affiliated in anyway, I just enjoy watching the guy's videos!

#28> Lock It Up and Throw Away the (Encryption) Key That might get you into a lot of legal problems, [1]. [1] https://en.wikipedia.org/wiki/Key_disclosure_law
You mean filling your disk with some random bits? Is white noise already illegal?
Yes, in any place where you are forced to disclose encryption keys.

#29What about the chemical option - attacking the board with a strong acid. Are there any readily available acids that would do the trick?
Re: How to securely recycle or dispose of your SSD
#30One option they don't mention: Thermite. Seriously, if you physically melt the chips, they're not going to retain any information.
Thermite sounds a bit excessive for a typical home or office. How about baking in an oven or roasting on a grill? Is modern flash memory fragile enough to be destroyed irreversibly at 230C/450F?
Maybe.
They have to be rated to survive those temperatures for short periods of time during reflow soldering.
Apparently flash memory is rated to last a minimum of 10 hours baking at 125c, or 360 hours at 85c. The decay is exponential, so in theory 30-60min at 230c should do a lot more damage.
But I'm not sure you should rely on it, that 10 hours @ 125c number is for when the bit-errors exceed the capabilities of the ECC. The data will be partially recoverable for much longer. Or you might have some flash which does a lot better than the minimum spec.
