Sansa Clip+ Storage issues

[capybaraa]

I just purchased a Sansa Clip+ and a 128 GB micro sd card to store my music on. When I tried uploading about 16 GB of music onto the Clip+ I got an extremely long loading screen so I figured that Rockbox would help with processing the data. Anyways, now I'm at the point where I have attempted to upload 16 GB of my music onto the player but only 9 GB of the audio files are in the music library whereas the other 7 GB are in the files library but only contains empty folders where the other music should be. Also, whenever I reboot the mp3 player with the stored files, I get an error message and the rockbox logo; but when I turn the player on without the card in it, then put it in it works fine (other than the empty folders).
The SD card is formatted as FAT, and I am using a mac to upload my files onto the Sansa Clip+.

UPDATE: I fixed it, I just went into the database settings and scanned the sd card

hi, i purchased the following card:
SanDisk SDSDQUN-128G-FFP-A Ultra Class 10 Micro SDXC 128GB Speicherkarte inkl. Adapter (UHS-I, 48Mbps)
and formated it FAT32.
It is not recognized by Clip+ (Rockbox FW)?

What SD-Card do you use?

Does it work in the Sandisk firmware?
