[ale] Linux Ext2 Unformat?

[charriglists at bellsouth.net]

Greetings all,
     Had a little goof during a late night session.  Is there a utility that can unformat an ext2 partition?  I was aiming the format at /dev/hdb1 and hit /dev/hda1 instead.  I googled for info on it, came up with R-Linux.  R-Linux runs in windows of all places, but I just couldn't seem to make it work.  Any assistance, pointers will be greatly appreciated.

Thanks
