I have a Sata drive that I tend not to use much and I want to sell it

When I try to format a drive, it leaves behind a lost+found folder and it's also in the linux file format and I'd like to format it to the windows one.

better obfuscate your personal data on the drive for privacy. ADDED: two methods

  • sudo dd if=/dev/random of=/dev/sdx bs=1M
  • sudo shred -z /dev/sdx
    Replace sdx with that of the appropriate drive.

You have to flood the drive with zeroes sometimes in multiple passes. Use data recovery software like Rstudio to make sure nothing is left. Warning, doing this can cut the drive's lifespan in half.

shred command ought to work as dezi wrote above. (on linux OS) You may also use a third-party file/drive shredder application on Windows or Mac to deal with the drive in question.

#
  • there is also Shred OS, a bootable live ISO you'd use much in the same way as linux live, or gparted-live. Handy for cases where the drive in question can't even boot its own OS, and u want it securely wiped.
#
  • once drive is cleared, make a new partition table on it (GPT is the norm these days), then lay down an NTFS filesystem on it. Can easily be done using gparted.

oh o.o
I didn't know that personal info could remain like that...

#

might not bother selling it considering similar drives are only going for 30 bucks anyways lol

this is another way. and instead of quick-erase, you choose 'overwrite'
