Is this disk defective? [closed]

I try to attach a USB external disk drive to my Ubuntu laptop (running 15.10), but it doesn't show up. The disk may be defective, but how can I tell for sure? The drive is a Seagate Barracuda 3Tb disk in a RaidSonic Icy Box IB-351Stu-3B enclosure, which is the brand name for an ASMedia AS2115 USB device. When I power up the drive, it gets recognized, as seen in dmesg:

And lsusb -v can see bits of it, too:

But the drive is not recognized by gparted or any other disk utility.

Should I conclude that the drive is defective, or do I need to install any special drivers for it?

EDIT: when connected to a Windows machine, the device is recognized (and a driver for it is installed from somewhere), but then Windows offers to format the disk, then fails with something like "formatting failed" with no further information. I wouldn't know how to begin to debug that, and anyway I want to use the drive on a Linux computer.

EDIT2: even though the device claims to be USB 3.0 compatible, I have connected it to an ordinary USB 2.0 port.

I have replaced the disk with another one and this time the disk was recognized and could be formatted. The large Barracuda must have been defective. I will close this question in a little while.
