This is incorrect.  The correct command is fdisk -u=sectors /dev/sdb -
no "1" at the end.

/dev/sdb1 IS the first partition on /dev/sdb.  If you run fdisk on it
then you end up creating partitions inside that partition.  Linux
displays these as /dev/sdb1p1 and so on.  When you create a filesystem
on /dev/sdb1 you overwrite the nested partition table, and so the
nested partitions go away.  I doubt you can boot off of nested

What you want to do is create a partition table in /dev/sdb, and
however many partitions as you need.  Those will then show up as
/dev/sdb1, /dev/sdb2, and so on.  You can create filesystems inside of
each.  You shouldn't see any partitions with a letter p in them.
