hey Garbanzo, the restore file should work - if it did not then you can go - Open RegEdit.exe and go to:
delete the DriveIcons key insode registry and all should go back to normal after reboot if not right away. That is how it works for my machine anyway. Sorry you had to run SFC. It was not reverting everytime for me as well. Guess maybe it's better to delete key than run reg key fix, as it only removes sub keys and not the driveletter key itself.
I also have these black icons from DA - i am posting the imageres file only - that is all i use.
I am using these icons now without the driveletter icons. The icons are form the DA inverted theme found Sewen Style Expansion Pack by ~rtwinph on deviantART
I am using these icons along with this theme - Elegant GRAY VS - Windows 7 RC by ~DjabyTown on deviantART
installed theme using this patcher - TCP-Z, Best TCP/IP Patch: Universal Theme Patcher (v1.5, Build 20090409)
