delete rom slot 1
I have had issues with HD installing in slot 1, I am not sure why but slot 2 or 3 have worked much better for me when installing Hyperdrive. I would suggest trying this and see if it works for you as well.
Hope this helps!
Currently using RLS14 and Latest Safestrap version on MJ7 Base in slot 2 for call recording and touchwiz!\Rom Slot 3 Created searching for a AOSP style like Eclipse to run in slot 3 (open for now and suggestions!)
Razr maxx also supporting hashcode running SS 3.11 and RLS8 slot 1 with Nexus 4.4 experience in slot 2
