Is there a way I can reduce the recovery amount?
That Recovery Partition, with drive letter E, was put there by the manufacturer. 21GB.
I'm assuming this is a prebuilt system?
This is used to bring the system back to factory condition.
There should be a function for you to create a DVD stack or USB from that Recovery partition. Look in the user manual for how to invoke this.
This is useful for if you need to do a Factory Reset after the original drive dies.
With that function living on that original drive...if the drive dies, you are Out Of Luck.
