Did you run e2fsck against /dev/hdb or /dev/hdb1?  /dev/hdb is the entire 
disk.  /dev/hdb1 (or 2, 3, etc....) is the file system that you want to 
check.  Running e2fsck /dev/hdb will give you that error even if all is well. 

Try: e2fsck /dev/hdb1.  Hopefully, you haven't started the reinstall yet.  :^|
