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

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.
