SP1: Can I delete all the small recovery partitions? topic

Hi guys! After I move the recovery partition to an usb flash drive using the windows procedure, I can't merge the free space on the ssd because of some small partition on the drive. It is the partition number 5 in the image below.

My question is: if I delete the partition 5, will I be able to reset my surface using the usb drive I have created before, or not? Why does this partition exists? Why it should be there just in order to prevent the partitions to be merged?
Thanks
