I'm trying to mount an external Hitachi hard drive. Supposedly it's USB 3.0 and backwards compatible with 2.0.

I can see it with lsusb (it's "SimpleTech"):

Bus 002 Device 002: ID 045e:00dd Microsoft Corp. Comfort Curve Keyboard 2000 V1.0
Bus 002 Device 003: ID 046d:c016 Logitech, Inc. Optical Wheel Mouse
Bus 001 Device 011: ID 4971:1013 SimpleTech

Additionally, the system appears to see it's a "high speed USB device", and it uses ehci_hcd. From "dmesg | grep -i usb", plugging in and out a few times:

[1914076.788026] usb 1-8: new high speed USB device number 9 using ehci_hcd
[1914118.992058] usb 1-8: reset high speed USB device number 9 using ehci_hcd
[1914466.772118] usb 1-8: USB disconnect, device number 9
[1914478.188029] usb 1-7: new high speed USB device number 10 using ehci_hcd
[1914516.944023] usb 1-7: reset high speed USB device number 10 using ehci_hcd
[1914828.148003] usb 1-7: USB disconnect, device number 10
[1914832.184073] usb 1-7: new high speed USB device number 11 using ehci_hcd

Also, it shows up as /dev/sde. However, "sudo fdisk -l" doesn't show it, gparted doesn't see it, and "sudo parted /dev/sde" gives me "No such device or address".

I know the hard drive works, because I can use it in Mac OS X 10.6 (it's formatted FAT32).

What can I do?

I don't know if it's any different from gParted, but I usually use the Disk Utility to mount something that hasn't automatically? –  jfy133 Dec 12 '11 at 9:19
James, Disk Utility is a Mac OS X application, and I'm looking for a Linux solution. –  emchristiansen Dec 14 '11 at 4:18
...well if I type in 'Disk Utility' in the dash,it comes up. It's certainly a program that comes with Ubuntu 11.10 by default. It's made by Red Hat. –  jfy133 Dec 14 '11 at 16:13
Is it visible in Nautilus as unmounted? –  Abhijeet Dec 24 '11 at 15:42
Can you mount it manually? –  chris Dec 24 '11 at 16:00

As James suggested, using Disk Utility seems to be a good idea.

I'm having the same issue with a new Hitachi external 2T drive as well.

The drive is detected properly with Mac OS X "Lion" (10.7.2). The disk has a MBA partition table with a single NTFS 2.0TB partition.

I found a hint that black-listing the "uas" driver would help.


I tried a "rmmod uas", but this didn't seem to help. After a reboot, the drive seems to be detected and working properly.
