Yes it did say f drive when I clicked on box and I got all data in you scanner will be erased ??? The card is formatted should I erase scanner info and start over
Yes, erase the scanner info. What I believe that does is remove any recordings, Favorites Lists, etc. that might be on the card. Since a re-formatted card doesn't have such things, it's kind of moot. Still it is something done when you click the Clear User Data.
After the recordings, Favorites List, etc. are removed, the next thing done during the Clear User Data process is that the correct files are installed on the SD card. This is done by the program - no special steps are needed by the user.
Following that, write your profile and Favorites Lists to the scanner.
Sometimes folks try to "over think" what is going on when they are doing something to the scanner via Sentinel. They just need to sit back and let the program do its thing - it's a lot simpler than it might appear to be.
