Hi,

Have some HDDs to write zeros to entire disk and would like to use a bootable DOS Floppy to do this.

Appreciate any recommendations.

If you think a bootable Floppy Linux app is faster would be interested. I do use DBAN 1.06 from bootable Floppy but only want to write zeros to these HDDs so am checking if there is something faster.

Thanks

Ken

You could download MHDD and make a bootable floppy or USB and then use the erase command.

In linux you can copy /dev/zero to the device you wish to erase.

Example, using ddrescue where x is the actual disk number you wish to erase:

> ddrescue --force /dev/zero /dev/sd[x]

Hi Luke,

Was reading some basic info MHDD erase command but it did not mention what the options (if like DBAN...) is it only Zero writing?

I normally use Windows so Linux is challenging for me.

DBAN uses SysLinux so did some checking The Syslinux Project http://www.syslinux.org/wiki/index.php? ... ux_Project but have not found any info if there is a Linux write Zeros to HDD app that can use with it on a bootable floppy?

Am not familiar with ddrescue will it fit on a bootable floppy?

Thanks for your suggestions!

Ken

Or use security erase ....

But beaware sometimes it will not erase at all (in particular with Samsung drives.

That brings to mind a question : when using ddrescue or hddsuperclone, when enabling the option for filling the bad positions with something ( eg, "BADBADBAD" ) theorically this would overwrite all of the destination disk ? So that it would not be necessary to clear the disk before

i use HDTune. if you use DOS you waste your time and electrical energy.

:shock: :shock: :shock:

You can use DOS + MHDD + "fasterase" and it will issue the Security Erase that is drive internal and you can't beat it in terms of speed.

HDTune will be slower to write to the drive ! I don't see why DOS would be slower/faster as any other OS. You are limited only by the capability of the drive to write to it's own sectors and by the way the tool sends the data to the drive for it to be written.

If you eliminate the "ATA channel" and the necessity for the application to send data to the drive to write on it (even if it's just a zero pattern) and if the drive can erase itself without the need of extra data from the external tool then you will go as fast as you can and you can't beet the speed of the drive itself erasing itself so ..... Just use Security Erase !
