Hi,
thanks for your advice. VMware splits vmdks into small chunks to address this issue with FAT32, but unfortunately, I do have other files on this volume I need on Windows and Mac, that are bigger than 4 GB :-(
That is why I went with exFAT. I don't have a problem with lesser security, as I backup what really needs to be save, it's just a volume where I put for example test environments (multiple VMs) and need access to it from Windows and Mac.
So I hope that exFAT is not really the issue here, although it seems to be! Maybe it is because of FireWire, I could not test a NTFS Firewire Volume with VMs on it under Windows yet.
Thanks though
