Don't boot 2.11 and try to write to your hard disk formatted with 3.x.  
DOS 2.x formats hard discs using a 12-bit File allocation table.  
DOS 3.x formats hard discs using 16-bit File Allocation Table entries.
If you write to a hard disc formatted with 16-bit FAT entries using an
operating system that thinks its dealing with 12-bit FAT entries, you
can kiss the data on your hard disc goodbye.
