Need HDDErase That will work with SATA ...

that last comment is unwarranted. this is nothing like a format.
as a very long discussion on this forum amptly illustrates [with citations from professional journals, articles, blogs] formatting a HDD does not securely destroy data. To think otherwise is taking a huge risk if one does not want thieves recovering files.

Disk - Clean and Clean All with Diskpart Command

8. To Use the Clean All Diskpart Command
NOTE: See the green INFO box at the top of the tutorial for more information about this command. This command will wipe the HDD, and perform a secure erase. However, it will take a long time to do. It's best to only use this command if you wanted to help make sure that the data on the HDD cannot be recovered say when giving or selling the HDD to another person.

A) In the elevated command prompt, type clean all and press Enter. You will see the command prompt below as is until the "clean all" command is finished. (see screenshot below)

NOTE: This will take quite some time (several hours or more) to finish depending on how large the disk is since it is writing over each and every sector on it to zero. Think of it as being like a full or low level format.

fwiw, and for future fellow travelers: - Enhanced Secure Erase [which i think is drive-dependent] as follows [the utility put out by cmrr-ucsd supports]:
"CMRR has established minimum mandatory properties of an Enhanced Secure Erasure algorithm which provide
erasure security equivalent to most implementations of physical destruction and in a much shorter time. CMRR
specifies a minimum of two random data writes of all physical user sectors (including reassigned sectors),
where each write is offset off- track opposite to the other by at least 10% of the track pitch. The number of
physical sectors not successfully written should be reported, and any defective sectors which could not be written"

I have to agree that a clean all in DiskPart is completely sufficient for making any and all data unrecoverable through software means, which means file or partition recovery software of any kind.

Beyond that, a truly secure erase using multiple passes only makes sense if you actually have a real concern that someone might physically disassemble your HD (which you can only do in a clean room like those in professional data recovery institutes) and then connect it to special hardware capable of directly grabbing the analog signal from the read/write heads and examining it for remnants that could be reconstructed to form the bits previously overwritten with zeroes. This isn't stuff an average consumer can get their hands on, unless they're filthy rich maybe.

Really, you'd have to have some kind of industrial secret worth millions of dollars or illegal financial records or military research or things like that to even consider this an actual risk worth worrying about.

A single-pass overwrite with zeroes is totally sufficient if you're just selling/donating your system containing the HD.

try using HDDGURU FreeWipe Tool....just google it , supports all hard-drives , might have to run it in emulation mode for what ever OS your using but otherwise it works

I actually have used that one on light tasks, and read the underlying detail. Not sure it is as effective as Secure Erase - particularly the -Enhanced. Their low-level format util, however, seems to be solid, just understand that that tool does not address this subject
