I am using the USB MSC code in my project. The project works fine and I am able to see the file system mounted and file being created in the logs. When I plug in the device into my laptop, I can see the device as a drive. However, when I click to access the drive, it asks me to format the drive and I am not able to view the contents of the drive. What might be causing this issue?
Hi
The file system will need to be formatted in order for the device to be able to mount the file system and operate correctly. If it's not already formatted you can use the f_mkfsI() function to format your drive. That function is documented here: http://elm-chan.org/fsw/ff/doc/mkfs.html
Best regards,
Simon

Hi Simon,
I have already used this function in my code. Please take a look at this file. I have used the format function "f_mkfsI()" inside the "fatfs_init()" function.
