I hope there is a simple answer to this question (fingers crossed): how do I
overwrite an existing partition (hda2 for example) with all zeros
(essentially blanking the partition clean in preparation for installing
Lenny), without destroying the partition table? I've used the shred command
to wipe partitions before, but it messes up the partition table along with
it. The purpose is that I have a 200gb hard drive with music/pics/etc. on a
separate partition from the OS that I will mount via fstab upon boot. I've
searched around and the dd command can probably do it but haven't gotten the
command line to do it. Any thoughts?

Thanks in advance,
Mark

Something like dd if=/dev/null of=/dev/hda2 bs=4096

Thanks Aioanei, I'll give that a try. I know it's a dumb question I just
don't want to get it wrong!

Currently I have 180 of the 200 GB partitioned containing music, pictures,
etc. and an old OS installation on the hda2 partition. I'd like to keep the
180 gb partition in-tact, not damage the partition table, and fill the 20 gb
hda2 partition with zeros so I can install Lenny.

Thanks,
Mark

"Simply" install (using expert mode) onto the relevant partition.
During installation, you'll have an opportunity to mkfs each of the
partitions. Skip the "data" partition, but then tell the installer
to mount that partition as "/data" (or whatever).

Just make sure you first have a backup copy!
