Just thought I'd pass this along in case anyone else is having a problem with errors when they update there rescue area. I installed Comodo CIS and when I updated the rescue area I had errors with it. The errors were GRH:: Create file and Windows\system32\drivers\sfi.dat. When I uninstalled Comodo CIS and updated the rescue area the errors went away. Comodo has some locked files. I tried updating several times before I uninstalled Comdo and always had the same errors. I believe it's the anti virus portion of CIS that's causing the problem.
