which I don't think knows about exFAT.
&nbsp;
So, formatting on a PC won't work (unless I use third party software to enable ext3), because FAT32 limit is 2 TB or so :(
&nbsp;
I do plan to format it on a Linux box, but haven't had a chance today.

The 1100 (like all 4.1.x systems) is limited to 2 TB drives. The issue isn't related to ext3, exfat - it is more basic. &nbsp;4.1.x systems can't handle GPT formatting, they only support MBR. &nbsp;And that is limited to 2 TB. &nbsp;There is no workaround.

When I tried it, my 5 TB drive got formatted as about 300 GBs (without telling me)

Googling seems to show that supporting more than 2 TB isn't possible with fdisk (which my Netgear used),

but that one has to use GNU's "parted" (not on my Netgear).

I'm still investigating :(

Try formatting the disks on a PC

What firmware are you running on the ReadyNAS?
