corrupted directory, I can not clear !! help !!

[Dave Selby <dave_arahan@yahoo.co.uk>]

I had hdb partitioned as

hdb1	windows
hdb2	debian
hdb3	linux partition for archive

I have since moved debian to an 80GB drive hda.
I want hdb to be a single linux partition I can use to archive data.

I used linux fdisk to remove all partitions on hdb, I then created one 
partition on hdb, ie hdb1 taking up the entire disk.

I ran mkfs.ex2 /dev/hdb1

All AOK
Except when I mount it and go into the directory I get .....

debian:/mnt# cd archive/
debian:/mnt/archive# ls

Im stuck guys. I have tried e2fsck, it check out aok but somehow I am stuck 
with a corrupted DOS directory which I can not clear ??

I need an equiverlant of a DOS format command I think, the nearest I can find 
is fdformat but this is only for floppy disks.

Any ideas how I can wipe my hdb disk clean ??

Many thanks for any help
Dave
