Mac OSX Bootable Disk error code (-9999,0)

Hi I am trying to make a bootable disk with OSX El Capitan so I can continue to use this computer with a newer operating system.

I have installed the disk named it (INSTALLER) and formated it to MAC OSX Extended (Journaled) with a GUID Partition

I downloaded the OS X El Capitain install package and placed it in my applications folder.

I then go to the Terminal and this is the error i get:

Last login: Sat Apr 18 20:15:27 on ttys000

Users-iMac:~ user$ sudo /Applications/Install\ OS\ X\ El\ Capita

> n.app/Contents/Resources/createinstallme

> dia --volume /Volumes/INSTALLER --applic

> ationpath /Applications/Install\ OS\ X\ El\ Capitan.app

Ready to start.

To continue we need to erase the disk at /Volumes/INSTALLER.

If you wish to continue type (Y) then press return: Y

Failed to start erase of disk due to error (-9999, 0).

A error occurred erasing the disk.

Users-iMac:~ user$

Any insight on how to complete the making of my bootable disk and fix this error?
