Again note that you used /dev/sdd not /dev/sdd1

You won't be able to remove files from /dev/hdd1 by doing things to
/dev/hdd. You _will_ be able to corrupt the file system but it is FAT
so it could show up as an inability to remove files.
Try:
# dd if=/dev/zero of=/dev/hdd
this should zero the whole drive
then use cfdisk and create /dev/hdd1 with the whole space.
Then use mkdosfs on /dev/hdd1 not /dev/hdd.
Then mount /dev/hdd1 and see what's there.
