When attempting to reinstall OS El Capitan so that I can donate it to a charity, I opened the computer with command R, I click on erase and then it says erase hass failed. Now what?

Original Title: Erase has failed
MacBook Pro 13″, OS X 10.11
The charity recipient would be very happy if you made a latest supported bootable macOS installer USB thumb drive for that Mac model.
And donated also that thumb drive with the Mac erased, and re-installed so it boots to the factory settings ready for the recipient to enter his/her personal info.

Sometimes the erase will just fail for unknown reasons. Try immediately erasing it again. In fact, select the physical drive to erase so it recreates the partition table as well.
If it still fails, then the internal Hard Drive is likely bad.
From disk utility in Recovery pick the erase format as Mac OS extended (journaled). Be sure you select the top drive line when erasing.
