I have found out that if I set allocation unit on exFAT to 2K, in best case I have a drive that is not recognizable and worst case blue screen.
Win 11 23h2.
Has anyone had a same issue?
Thank you!

It seems to work as expected with the 2K cluster size. Perhaps you're using an older version of the RAM Disk app?

There were a couple of issues related to custom cluster sizes that have been resolved in recent updates:

Version 4.4.2: Fixed an incorrect cluster size issue when using custom sizes.
Version 4.2: Fixed an issue with exFAT formatting for large disks with small clusters, where the FAT bitmap exceeded 64 bit.
