Thread: Nüvi 3790

This is a situation that occurs when Windows detects errors in the file structure and tries to recover them
I would definitely advise you to backup the entire content, format the memory completely and then restore the necessary files. Preferably install fresh system via Garmin tool

In principle I will not format the drive. It seems to be without any defects, or at least, Windows has analyzed it and everything is fine.

I have read about it and I have not found any step by step that speaks clearly about how to format the drive.
I have doubts:
-If the nüvi drive is formatted, once formatted as FAT32:
-Does the PC detect the formatted drive?

-You tell me that it is better that I install a new system from Garmin Tool:
- Do you mean Garmin Express?

- For the installation of a new system:
- Did I have to copy the backup files to the formatted drive first, or does the drive have to be empty?


Thanks Boki
