I once performed a low level format on a hard drive like 7 years ago, but it booted of a floppy disc. Now i want to sell a couple of hard drives, and i want to securely erase them, but i dont want to boot from floppy. Is there any good utility that does that directly from Windows?

Diskpart is built in windows, use the clean all command and it will wipe them.
  1. Open the Start Menu, type diskpart, press Enter
  2. Type list disk, press Enter
  3. Type select disk X (where X is the number your drive shows up as), press Enter
  4. Type clean all, press Enter (this will take a long time, about 2-3hrs for a 500GB-1TB drive)
  5. Type create partition primary, press Enter
  6. Type format quick fs=ntfs, press Enter
  7. Type assign, press Enter
  8. Type exit, press Enter

Also, CCleaner has a drive wiper tool as well if you want to use that instead.

Are these utilities as good as a low level format? Will there still be any recoverable data left if i do a clean all or use ccleaner/easus?

Since I'm on a haste cause i need to deliver these drives tomorrow morning, i just started with diskpart since it does not require any software installation. Bad thing is that it doesnt give you any completion percentage and i wont know how long it will take.

But I'm still worried, Is clean all as good as a secure wipe, and is the wipe as good a low-level format? I need to be certain that the guy i sell to wont recover any of my data in case i may have anything sensitive there.

What you ask of us is to tell you it will be wiped....
The only way to be sure is for you to try and recover files.
If I was not sure, I would not sell drives

This is what CC Cleaner looks like...

Killdisk will do a 0 wipe in the free version.
Paid version will do a DOD level wipe.

DOS and Windows versions are available.

I just tried rstudio to see if i can recover anything and after a while i got a messgae that there is not enough space. Before i run R-studio i got 60GB free, and when i got the message i got like 24KB on my drive! I panicked and i restarted my computer now it seems i got 4GB free, but i cant locate where the rest of the files went.

*** happened? Why did my main drive fill up and i cant find any new files?

Define low level format. Window's full format does a check disk and a partition table rewrite. That will not make data unrecoverable.

Nope

The clean all is a secure erase. It writes 0's to all the secotros of the drive. Thus all data gone.

He won't be able to.

Use diskpart again. Just do the clean command, not clean all. You should have full capacity again.
  1. Open the Start Menu, type diskpart, press Enter
  2. Type list disk, press Enter
  3. Type select disk X (where X is the number your drive shows up as), press Enter
  4. Type clean, press Enter (this will take a long time, about 2-3hrs for a 500GB-1TB drive)
  5. Type create partition primary, press Enter
  6. Type format quick fs=ntfs, press Enter
  7. Type assign, press Enter
  8. Type exit, press Enter
If you are still having issue post a screenshot of your SMART data. You may have bad sectors or something.

No its OK, it must have been a bug. Now i get full size. I Run Piriformi Recuva on deep scan and found no file to recover. I am now on the second and final drive. This time I'm using ccleaner for the wipe so i can see how much time remains. Will run recuva again when finished and then hopefully sell the drives.

Thank you guys for helping me

Doesn't really feel like he took our advice...

Recuva is okay......but something more robust like getdataback might be able to find stuff.
I still recommend a DOD or higher level wipe.

Why do you say that? Obviously I couldn't try all the methods and software so i had to choose. I chose ccleaner and diskpart since they seemed to be the most accessible options for wiping. as for recovery, besides you naming "getdataback" right now, noone else recommended any alternative by name, just generally pointing me to trying to see if i can restore anything. Recuva is said to be a very good choice, so i tried that. And it found no traces so i guess i was safe.
