Hello Bob,
1. How big is your HDD and brand ? I hope not bigger than 2TB ?
2. Are you sure, you format it in FAT32 ? This is important ! Not only normaly Format on a pc in standard formatstyle with using the right mouse button and then format. In Windows you need a another Programm like “Fat32Formatter” to format your HDD in FAT32, Windows do it only till 32GB.
If you do this right im sure it will works with the SQ to Format your HDD.
