oh, yes, one more thing: what dmesg reports about it?

Thanks, pan64. I'm running a test for bad sectors on this drive at the moment. The more I look at it, the more I think it's a hardware limitation with the enclosure, and not the drive or partitioning or something. I think this is the messaging from dmesg that came out last time I connected it:

Since you are seeing two devices you could use the LVM idea I suggested at end of my last post.

What I found: this usb enclosure [may] have two different ways to access the disk. One of them is [something like] a direct access and I have not idea what is the other one [some kind of mapping??]. Probably you are right it depends on the size of the disk.

SOLVED.

It was the hard drive enclosure. With a new enclosure, I get:

Code:

$ lsblk -f
NAME   FSTYPE LABEL UUID                                 MOUNTPOINT
sda                                                      
├─sda1 vfat         639C-3488                            /boot/efi
└─sda2 ext4         78b35f52-b118-447f-9000-91b69d3f6d41 /
sdb

Then

Code:

$ sudo fdisk -l
[sudo] password for fatpie:

And

Code:

$ sudo hdparm -I /dev/sdb
