The Format function in the SETTINGS menu is only on the v2 model and the User’s Guide doesn’t differentiate between the two. If you have a v1 that would explain why it’s not there.
If indeed you have a v1 model, you can connect in MSC mode, make sure Windows is set to show hidden files & folders, and find the SYSTEM folder. Inside of this will be a DATA folder. Highlight this folder and delete it. This is where your player’s database is stored.
When you un-plug from the computer, and the player ‘refreshes database’ it will build an entirely new one of the current content on the player (and memory card, if inserted) rather than just appending the existing one. Your deleted song titles should now be gone.
