I have been attempting to do a Firmware Update or a Factory Reset after formatting my USB thumb drive FAT 32.  However, when I attempted to do the process of the update, it seems that my mixer will not find my drive for a particular reason.  Why is this?

There has been a recent discovery concerning USB thumb drive formatting problems with Mac OS X 10.11.X, El Capitan that is particular to the way you format the drive.  It's simple to correct, but requires selecting a few options in order to complete a Firmware Recovery or Factory Reset process.

These processes are mentioned below for your StudioLive AI mixer or AI PA Speaker:

StudioLive Ai PA Firmware Update Process

StudioLive AI mixer Firmware Update (via USB thumb drive)

StudioLive AI Mixer Firmware Recovery - Factory Reset

StudioLive RM series Firmware Update (via USB thumb drive)

StudioLive RM series Firmware Recovery - Factory Reset

StudioLive CS18AI - Firmware Recovery

 

In order to get the drive to format properly, you will want to do this:

 

1.  Once the drive is connected to your computer, make sure to go to:

Finder > Applications > Utilities > Disk Utility



2.  Make sure to select your drive as depicted here, leave name set to "Untitled" as a formality, and set Format to "MS-DOS (FAT)"

3.  Change Scheme type to "Master Boot Record."  This step is important as the drive will be "booted" into when doing the firmware update process or the Factory Reset.  Without this option, the drive cannot be seen.

4.  After verifying your settings look like the screenshot below, click "Erase"
