Thank you for the article but I am aware of it and that article says it's limited to 1Gb but it's actually 4Gb. My question was whether the format was limited to only being able to use FAT.
Have you tried this article as far as the manual update? It's about halfway down. https://www.cisco.com/c/en/us/support/docs/switches/catalyst-3750-series-switches/64898-upgrade-3750-stack.html
