When I said deleteing, I meant securly deleting.

If you don't care about deleting all the data, a much easier way is:
dd if=/dev/zero/ of=/dev/hda
It will run for awhile (without a progress bar) and then stop. Check
the man pages if you want to check the progress of the wipe.

Try man shred
Shred is the linux utility for cleaning hard drives.
Delete FILE(s) if --remove (-u) is specified. The default is
not to
remove the files because it is common to operate on device
files like
/dev/hda, and those files usually should not be removed.
When operat-
ing on regular files, most people use the --remove option.
CAUTION: Note that shred relies on a very important
assumption: that
the filesystem overwrites data in place. This is the
traditional way
to do things, but many modern filesystem designs do not
satisfy this
assumption. The following are examples of filesystems on
which shred
is not effective:
* log-structured or journaled filesystems, such as those
supplied with
AIX and Solaris (and JFS, ReiserFS, XFS, Ext3, etc.)
* filesystems that write redundant data and carry on even
if some
writes
fail, such as RAID-based filesystems
* filesystems that make snapshots, such as Network
Appliance’s NFS
server
* filesystems that cache in temporary locations, such as NFS
version 3 clients
* compressed filesystems
In addition, file system backups and remote mirrors may
contain copies
of the file that cannot be removed, and that will allow a
shredded
file to be recovered later.
Autoclave uses Shred and I use ext3 filesystem and Autoclave wiped my
disk but I didn't test the disk (WD 120GB) to see how it performed.
