Wipe HDD - FDISK fails to work

[David_Jones]

Hi All,

I am trying to wipe a HDD to completely start from scratch.

I had it dual booting Red Hat 9 and Win98 SE, but I want to scrap that, and install something else.

I am running FDISK from a Win98 Boot Diskette, and it has successfully deleted the two non-DOS partitions (Linux) leaving me with a single Primary DOS partition, and an Extended DOS Partition.

If I use option '4' it tells me that there are no logical drives in the Extended DOS partition.

However, if I try to remove that Extended Partition, FDISK reports that there *is* a logical drive that needs to be removed first.

If I try to remove a logical drive from the extended DOS partition, FDISK tells me that there isn't one there.

Any ideas?

Can I just wipe the MBR in some way perhaps to delete references to the existing partitions, and then use FDISK to re-create from scratch?

Thanks,

David.

PS: Just in case anyone is worried - I know that I will lose everything in the partitions, that is fine, it is just a play PC that I use to experiment with different OSs etc.

Darik's Boot and Nuke will get the job done and then some. It will completely wipe your hdd clean. Just follow the instructions on the site.

You could do a zero fill using the HDD manufacturer's disk utilities, then repartition with fdisk. Linux partitions are non-dos (ext3, for example), so fdisk cannot touch them.

By doing a zero fill, the HDD is wiped clean, ready to be used again.

When I was playing around with Linux I had to do as force_flow suggested in order to reuse the drive in Windows.

You may save the time zero fill takes by downloading and running delpart from http://www.russelltexas.com/delpart.htm

I didn't know about that program when I used zero fill and don't know if it will work but it only takes a minute to try.

Hi Guys,

Thanks for the advice - you were (of course) correct that FDISK cannot remove the Linux Ext2 (or Ext3 ?) partition.

I used the Linux app form a boot disk as suggested and it is all fixed.

Thanks again,

David.

Depending on what you use, yes you could be using ext2 or ext3.
