Newbie having trouble with SD files not being found


I just recently started my saber building journey. Having a blast learning so many new skills. While configuring my new board, I am seeing the following errors in the serial monitor:

EVENT: Twist millis=63890


SD card is busy, flags= medium

SD card is busy, flags= medium

unit = 0 vol = 0.00, Playing Noble/hum.wav

File Noble/hum.wav not found.

SD card is busy, flags= medium

unit = 1 vol = 0.50, Playing Noble/out/out1.wav

File Noble/out/out1.wav not found.

humstart: 955

I am seeing these file names in the folders on my SD card but it is showing “not found”
any ideas? Thank you!

This means that the computer has the SD card mounted.
Do the “safely eject” thing, or program your proffieboard without “mass storage” and this shouldn’t be a problem.
