Your response is helpful Lennart, and this ignorant ex-mainframer even believes he understands. Thank you.
before going further, since my disks are empty, based upon this from the internet:
MBR is compatible with legacy and older operating systems that do not support GPT. On the other hand, if you have a newer computer with UEFI firmware, GPT is recommended for better compatibility and support for modern features.Jul 11, 2023
should i format with a GPT partition table? IIRC every system I have seen (other than Sun) has had a MBR partition table. to make sure my older computers can access it (hopefuly won't need to), will any operating system that supports 4 terabyte filesystems support GPT?
I'll give you my opinion. Others vary. There's no way that the OS plus software, config and cache take more than 1TB, so I make my root partition on an NVMe either 1TB or 500GB. Then I bind mount the rest of the mount points with space on a 14TB, 7200 RPM spinning rust. That 14GB is of course formatted GPT, and because it doesn't boot, it needn't have UEFI for the spinning rust. Meanwhile, the small NVMe or SSD doesn't need GPT, so it can be partitioned the old MBR way So if, and this is a big if, your motherboard supports MBR well, in my opinion this is currently the best way to go. However, note that some motherboards make it very difficult to boot from USB or DVD via MBR, sometimes requiring a trip through the BIOS setup screen. Also, many or most bootable DVDs and USBs can boot MBR *or* UEFI, but not both. SteveT Steve Litt http://444domains.com
