Format HDD hard drive?

Hello.

I want to format my 2TB HDD because I want to sell it.

To prevent data from being recovered, it is recommended to choose a more complex formatting.

The program offers the following options:

Which one would you recommend or which option is sufficient?

With such a modern HDD hard drive, one-time overwriting is absolutely sufficient. Since the traces slightly overlap, there is no technical space for any residual magnetism.

It is much more important to verify that the tool has actually destroyed all sectors (or if you want to make it just sample the last few sectors).

I am still concerned that small reserve areas (reallocated sectors) could have old content, which can also be done with the 35. Overwrite would not overwrite.

All that is below the selected option of BSI, I would classify as “paranoid”.

After the post has been relocated, the thing does not seem to be quite clear… I’ll give you the right thing, so even the more eager expert will rub on it. We had only in the company the discussion of how large the splitters can be at edge length of an HDD when they come out of the shredder to satisfy a certain standard.

With you it is so, you want to safely delete your HDD to sell it afterwards.

I’ll tell you very honestly about the technical side:

  • You delete all partitions in Partition Manager or with Diskpart
  • You let a deletion program read about what all bits writes to “0” or better writes a random pattern of binary numbers

If you are not a sought-after state enemy or top spy, or if you do not have any plans for a working time machine on the HDD, that is technically sufficient.

No one with normal technical means can then restore any sector. Sufficient for private things.

Now you’ve been doing the right thing and obviously got you a DBAN clone and want to delete your HDD. The standards that you see here are almost all military safety standards where x-fold safety is predicted that even with future technology, no one can restore you a byte of the original data even in 50 years.

The origin of this consideration was when HDDs of a still quite young generation with huge plates and huge track distance after the erasure had yet to prove a weak residual magnetism with which – appropriate intelligence technique was assumed, then bit for bit could be closed to the original data.

Nowadays, however, tracks are already written overlapping with such a small track distance that this is hardly possible today.

On the contrary, be careful not to ruin your HDD. We already had the same debate in the company when it was decided to safely erase out-ranked technology and output it to employees instead of shreddering when they then suddenly had newly assigned sectors in the SMART values after 7 runs. This is because things are getting hot, so make sure that the temperature does not rise above 50°C, because HDDs do not like it.

If I’m going to be safe, I’ll take the Gutmann-Method choose, although of course this takes longer.

After only games (completely inaccessible) and school stuff were on it, I would say: choose 2 or 3 passages.

Honestly, if you’re doing it for the Mammon, you’re definitely doing something wrong for me.

And whether it’s worth it, honestly: Can’t smell what you have on it. If you are Prof. Zweistein with the quadrature of the circle, then it is worth choosing the Gutmann method. But if you’re just Otto from the neighborhood, who has unobtrusive stuff on it, the standard formatting is enough.

Well, I’d do 7 passages.

ABER, for a used 2 TB hard drive you might get 10 – 15 €.

It’s not worth the effort.

Doesn’t pay for €10-15. Really, I would rather use the hard drive myself

Okay, everybody like he needs.

I have 20 times, and it still seems to me too little.

there is never too much storage. Trust me, you will regret it right

Well, I don’t need her

Like that? You can never have too much memory.

Copy a CD with the Wendler repeated to the record until it is full. There are also Russian ultracrackers struggling to investigate this thing.

For your purposes, the “Löschprogramm: Gut” option is completely sufficient. This program overwrites the data several times, making recovery almost impossible.

Good luck on sale!
