I’m trying to upgrade my HD to a 4TB drive. However, I can only see 2TB of the drive. I can’t find any info on the max drive size of the motherboard but it seems like it should handle 4TB. I’ve upgraded the BIOS but that didn’t help. There seems to be a firmware upgrade but the only upgrade executable is a 16-bit application. I cannot get that to run on the 64 bit (Windows 10) machine. I tried compatibility mode but to no avail and I don’t even know if it will work.
