USB drive for flashing BIOS - Allocation unit size?

[loosley]

I have a USB drive on which I am going to copy over the latest BIOS for my motherboard (Asus P8P67 PRO). I am planning on updating the BIOS using the Asus EZ-Flash utility.

I am going to format the USB drive as FAT32, as recommended by my motherboard manual. Here are the settings:

Capacity: 3.65 GB
File System: FAT32 (Default)
Allocation unit size: Default allocation size

My question is this:

When formatting a USB drive that will contain a motherboard BIOS file, does it matter what allocation unit size I use when formatting the USB drive as FAT32?

Hello loosley;

It will not matter. The 4 KB default allocation size is fine.
