wd write zeroes effectiveness

[bikasdas]

I want to write zeroes to my hard drive. I want to know how effective is wd write zeroes option? Is it impossible to recover data after the operation was complete?

 

[Mattios]

Yes, as long as the whole drive is written entirely with zeroes then yes.

 

[bikasdas]

Yes, as long as the whole drive is written entirely with zeroes then yes.

YES for what? for effectiveness or for recovery?

 

[Mattios]

What do you mean? Writing all 0s or 1s to the drive will erase it. You won't recover anything.
