Product Name: HP Probook 4530s
Operating System: Microsoft Windows 10 (64-bit)
I have HP probook 4530s ci5



having hard disk drive (HDD) of 750 GB.

Hard disk is of Hitachi (HTS727575A9E364)



I need to pass my notebook to someone for some days, so I needed to make sure my data is permanently gone.



I can use the disk sanitizer or secure erase option present in the BIOS. But I am not sure how much time it will take?



Can anybody please tell me what time disk-sanitizer option and secure erase will take for one pass?

U r rite, but it is said once started the wipe, you shouldn't stop it in the middle, it could damage the Hard Drive. So?

I did not even touch it fearing it could wipe before I want to. :(o_O

Do you have any experience with it, or please someone who experienced any kind of wiping may give me some comfort.

My experience differs from the above post that it will take 3 hours for one pass if the hard disk of 40 GB.


For other people like me looking for the answer to that question I am going to share my experience.



When I clicked on the disk sanitizer option, it gave me several choices like, 1 pass, optimum, gutmen, and custom. I choose optimum, it gave warning only that data will be permanently erased, it gave no time estimation, I had to do it, so I did it. After 22-23 Hours of wait, it did it. And the optimum was 6 cycles option. It showed the result as shown in the image attached.
