Data recovery and disk repair questions and discussions related to old-fashioned SATA, SAS, SCSI, IDE, MFM hard drives - any type of storage device that has moving parts

Hi friends
I am looking for a professional tool for my data sanitizing requirements. I have various hardware based tools as well as lots of softwares which works on device level (erase entire disk) , another disadvantage of this method is no reporting is there.
I have tested most of the so called DoD 5220.22-M tools as well as I am aware of latest update to DoD ( NIST SP 800-88 Rev1 guidelines)
Somehow I am not satisfied with these breed. Some vendors are charging exorbitantly ( blancco /Jetico etc)
I am keen to know if any more efficient software is there which I am not aware of.
My basic requirement is ---
1) It should support various eraser methods - one pass zero etc.
2) It should log process with device details (model / sn , start sector , end sector , start time end time and output of process). Active killdisk has some of the features but again it erases entire disk not individual files /folders etc.
3) If it allows to make live USB using winPE / any other OS that will be good.
4) It should give all available erasing options --- 1) files /folders 2) partitions 3) Entire disk 4)Dynamic disks and any other formats.
Thank you.

If you do not spend serious money here you won't get such a solution.
1. Only way to guarantee a full data destruction is a degauser.
2. There are areas, software can't access and overwrite. You would need MRT or PC3000 to access that.
3. Software won't work on anything that is flash based tech.

Hi nicoalbrecht
I do not agree with you. I think using pc3000 for disk eraser is only good if client is paying $ 500 per eraser otherwise its like using a AK47 machine gun to kill a mosquito . Ina typical enterprise customer there could 10000+ hdds erasing them with pc3000 will take ages. Instead with dedicated hardware /software one can erase no. of disks at a time. One can even use ATA commands (secure erase) .
There is no guarantee that whether disk is properly erased by degauser as there is no process log to confirm the same.
I think and as per US NIST SP 800-88 rev 1 one pass overwrite is more than enough to erase hard disk beyond recovery for most of the business level.
Recovery from remapped sector / overwritten track is not possible on commercial level and is important to CIA and pentagon only .For average users single pass overwrite ( zero fill ) is more than enough. (see attached pic)

Hi Spildit
Thanks a lot for the valuable information.

Personally I use this one. It gives you lots of options for the types of erase and generates certificates if needed. It does work with Windows 10.

Is it possible to get data back if I make low level format with windows?
I have tried before. It's filling zero. Any way to recover it ?
Or
If I fully write a random files (ex: videos ) over the my data , all to hdd capacity
Who can get back again old data? ?
Write random files over old datas from 0 gb to the end of hdd capacity.
And format it? . Easy . Who can get back ex data after then?
