mke2fs -j /dev/hd10to11 gets me with "no such device
I'm guessing, it should be '/dev/hda10'
I don't think you can create a ext3 file system for swap. Swap gets its own file system.
You may want to look into getting a copy of G-Parted live CD. You boot the system with it, and the whole partitioning and formatting process is handled graphically. Seems to work well.
