I have a USB 3.0 external hard disk which I am unable to mount. The entry appears in the "lsusb" command, but I do not exactly understand how to mount it.
This is the output for my lsusb command. "ASMedia Technology Inc." is the USB 3.0 device. I would appreciate some help in mounting and accessing the hard disk.
This the relevant output of my "sudo fdisk -l" when I connect the USB 3.0 HDD to a normal USB 2.0 port:
Disk /dev/sdb: 320.1 GB, 320072933376 bytes
255 heads, 63 sectors/track, 38913 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x8e0eee9e
Device Boot Start End Blocks Id System
/dev/sdb1 * 1 13 102400 7 HPFS/NTFS
Partition 1 does not end on cylinder boundary.
/dev/sdb2 13 38914 312466432 7 HPFS/NTFS
As you can see the sdb drive and paritions are listed accurately.
However when I connect the USB 3.0 HDD to the (ExpressCard34) USB 3.0 port and run the same "sudo fdisk -l" command, the sdb drives are not detected. They only seem to appear in the "lsusb" output. I have given the "sudo fdisk -l" output below:

This is the error given when I try to mount the hard drive:

I am using Ubuntu 10.10 (64 bit).
I have included a screengrab from Disk Utility for people who want extra info.

Any help is appreciated.
sudo fdisk -l
, you may have: /dev/sdb1, /dev/sdb2...; to mount that, at first make a new dir in /media, with(sudo) mkdir /mount/mydiscname
, than use the correct command:sudo mount /dev/sdbX /media/mydiscname
... the X refers to partition number! Am I right?dmesg|tail
after connecting your USB drive? What Ubuntu version are you using?
