After Install cannot see Router drive

I have a external USB 3.0 drive connected to my linksys WRT 1900acs router. After installing CIS my drive dissappeared. I uninstalled CIS and I still cannot see or access my drive. I went to my other PC and can see and access my external drive. So with my network place open and being able to see my drive, I installed CIS and after it was completed the drive dissappeared, Now I have 2 computers that cannot access this drive. I reinstalled CIS and started deleting rules, disabling the firewall and nothing is working. This is my last effort before I have to do I reformat to unblock whatever comodo has blocked on me.

Anyone have any suggestions?
