    Can data ereased with Diskpart -> Clean all, be recovered?


    I have a doubt about data recovery software. I'm planing on definitly deleting data on one of my disks for selling. If I use diskpart with the command: Clean all

    Can the data be recovered with data recovering software like recuva? Or do I have to use some special data shrading software if I don't want my data to be recovered?

    Thanks in advance.

    No, it can't. Diskpart's CLEAN ALL writes zeros to every sector of the disk, same as data shredding software would do.

    If this disk is an SSD then doing so should be avoided. Writing to every sector will reduce the life of the SSD. Instead you should use the manufacturer's Secure Erase option. For example, Samsung included this in their Samsung Magician software.

    Your link describes recovering after DISKPART CLEAN, which does not erase all data.
    The CLEAN ALL option that @ricardobohner asked about will zero every sector - there's no recovering from that!

    The really paranoid brigade will sat that even that is not enough, and you need multiple passes but this text from a web page says otherwise

    The notion that it takes multiple passes to securely erase a HDD is FUD based on a seminal paper from 1996 by Peter Gutmann. This seminal paper argued that it was possible to recover data that had been overwritten on a HDD based using magnetic force microscopy. The paper was purely hypothetical and was not based on any actual validation of the process (i.e. it has never even been attempted in a lab). The paper has never been corroborated (i.e. noone has attempted, or at least successfully managed to use this process to recover overwritten data even in a lab environment). Furthermore, the paper is specific to technology that has not been used in HDDs on over 15 years.


    I have tried to recover data after "diskpart clean", and have recovered it using easily available tools e.g. easus data recovery, and it is quite effective.

    However after "diskpart clean all" - nothing, zilch, nada!

    I just do not believe the multiple pass BS - I believe it is a myth put about by TLA agencies to scaremonger thieves, drug dealers, terrorists etc., and they are happy to let TV cop shows perpetuate the myth.
