command?

you guys know of a command to erase the hard drive, that contains RedHat v9 OS ?... thank you

rm -rf *

Seriously, just use any low level format utility, found on nearly any install CD.

Cheers.

umm I dont understand... sorry.. can you explain?

It depends on why your erasing it. If your just talking about formatting the drive, all Linux install disks come with the utilities to do that.

If your installing Windows, I think if you delete the partition and then remake a partition and format it NTFS that'll work.

If you want to wipe a single partition that has RH9 on it the mk(fs) commands do that for you. So for example to wipe the third partition on my primary HDD with ReiserFS you would do:
mkreiserfs /dev/hda3

It'll warn you about deleting all the information and proceed to format it.

Good luck.

Just boot from a Linux install disk and it can wipe the partition directly.

Use a Slackware disk from:

http://www.slackware.com or http://www.linuxiso.org

Boot from disk and remove that RedHat partition. You can back out of the current Linux install once the drive is clean.

It's easy just make bootable dos floppy. Copy, any partition manager on it .
And do as u like delete partition, resize it, format it with new file system.
I recommend to use "Ranish partition manager" small size and multi-file system option and it is free.
Fount it on :
