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 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub

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?
