Secure erase

is it safe enough
i selected 7 passes
is it enough

Should do.

One single overwrite with zeros is safe.

And the next time you got sensitive data just encrypt the drive before you ever need to erase anything.

2 Passes is enough for max-paranoia. 1 pass is enough for selling on ebay.

really?

then why does 7 pass erase exist

for military purposes

if its on an ssd then no amount of passes will help as it can still be recovered

sorry op im reporting you for cp.

Why does anything exist?
Why are you allowed to defragment an SSD? Why are allowed to spill water on your computer?

there must be some reason it exists if 1 pass is good enough

someone had to code it in

1 is enough.

there's a guy offering $1 million to anyone who can recover data from a drive that's been overwritten once. No one won.

There's a paper saying it's theoretically possible. Has an alphabet soup agency ever recovered information from a drive that's been written over with 0s? I very much doubt it.

Maybe that's what they want you to think

They've probably recovered data from a drive that was only passed once, but it takes weeks and thousands of man hours to recover small amounts.
Two passes and they don't even bother unless it's like nuclear codes or something.

They put it in because it's as easy as pressing '7' on your keyboard. There's no physical reason. It's like how there's a setting to turn mouse sensitivity WAY TOO HIGH. No-one uses that but it's there.

Old versions of Disk Utility even had a 35-pass option

7 and 35 passes are legacy from decades ago. They still exist so that paranoid people will use their software, and coding it in is as simple as "1) DO IT. 2) REPEAT 6 MORE TIMES."

Nobody knows because we cannot study it's source. We can assume it uses GNU/shred or works like that but that's a dangerous assumption. This means no number of passes is guaranteed to destroy anything.

Boot GNU/Linux from USB and use shred. 1 pass should be enough.

Don't need to read the source to find out what it does, you fucking freetard.

Secure erase in fact uploads the contents of your hard disk to the Utah Datacentre before running a single pass of zeroes over the files (it uploads the data while pretending to write the first 6 passes).

Kys pedo

What are you hiding from the storage forensic teams, OP?

You seem desperate to delete the evidence. I know this is evidence to something incriminating.

Yes, you do. Only the source actually states what the program does. The rest is marketing bullshit. It can tell you it wipes over 9000 times but actually just apply a reversible operation on it. You don't know. I don't know. Nobody but Apple software engineers know (and maybe some government officials guiding Apple).

...

You think you're funny or clever but you are making a complete fool of yourself. Are you that Stockholm syndromed that you simply take Apple's word for what their software does? You don't realize that the descriptive text from isn't from an engineer but a marketing department?

Stop acting this stupid. You might not be that stupid but someone that is a bit more gullible might actually take your shit for real.

Unless you actually have illegal or incriminating data which will be investigated by the CIA, 1 pass is enough.
Hell, just a quick format is good for most cases where you are trying to hide data.

How fucking paranoid do you have to be to assume you're being lied to about everything?
>You don't realize that the descriptive text from (You) isn't from an engineer but a marketing department?
A marketing department that put what the program does into words.

>A marketing department that put what the program does into words.
Holy fuck, Apple actually pays you for this shit, don't they?

No, but I would love to get paid to make fun of freetards. I already enjoy doing it for free.

Nothing but a sledge hammer will be enough

Well, at least you have the balls and the honesty to post your intentions so readers can take that into account when reading about your unconditional faith in companies that are only loyal to their stakeholders and the governments of the countries it operates in.

Thanks for the laughs, bud

>fill with horse porn
why would you even
...
right, so where i can find alot of horse porn ?

>Holy fuck, Apple actually pays you for this shit, don't they?
And you run this shit-line free. Microsoft must love you, but I bet you get nothing but a warm feeling.

>Microsoft must love you
I don't think so because Microsoft hasn't got he guts to open source their shit as well. To me Apple and Microsoft are basically the same shit were Apple sells a bit more devices and Microsoft a bit more software.

>I don't think so because Microsoft hasn't got he guts to open source their shit as well.
So, where's Microsoft's equivalent of Darwin?
Is there an equivalent to apple.com/opensource?
Among other things Apple looks after CUPS, Swift, WebKit and so on.

Gutmann 45 passes then physical destruction of the hard drive/ssd
its the only way to be sure

Microsoft contributes to the Linux kernel as well. Don't immediately makes them a saint. Their products are closed source. Apples OS is also closed source in a way I cannot study its source and compile it myself. This makes MacOS as unusable and untrusted as Windows. No winner here.

isnt one image enough? just dup until full or use gimp to enlarge until full.

>use gimp to enlarge until full.
It's hilarious and stereotypical that a Macfag thinks a computer can generate an image in RAM to completely fills its non-volatile storage.

What if the computer has more memory than storage? What if it used a drive larger than the one being erased for swap?

I'm pretty sure GIMP can store metadata rather than the actual image in ram, and the actual image is read from file.

That's only true for HDDs. There's no record of once zeroed HDD being recovered. At least by non-NSA level of expetise.

This user knows their stuff. SATA SSD controller may even be compressing the data written on it so when you write zeroes it just marks the area as empty and writes the first few bytes as zeroes. NVMe drives are probably safer.

In theory SATA SSDs should be erasable with ATA Secure Erase command but not all manufacturers implement it correctly or at all. If you have incriminating stuff on an SSD you should manually destroy it to be sure.

conveniently 45 passes kills the drive anyway

>the drive in op has 7.67 GB
