I just ticked another item off my Linux Mint post-install checklist: getting it to recognise my internal 7.25TiB hard disk. It turns out you can get 32-bit Linux to recognise these new, larger disks,
@dave r, provided the partition table on the disk is of type GPT, not the more traditional MBR. The only complication is that if you use a GPT partition table for your BOOT disk, then your BIOS must be specially configured for this (and reasonably up-to-date, so this rules out older BIOSes).
In my case, the internal 7.25TiB disk isn't the boot disk, so I just used the
gparted tool to reformat the disk as a GPT disk, then split it into 2 roughly equal partitions, about 3.8TiB and 3.5TiB respectively. Then I updated the /etc/fstab file with entries for these 2 new partitions and their UUIDs, so they get auto-mounted on startup. I then did a reboot to check all was well, and all was well.
