[Linux-usb-users] external hdd

Hi all .. I have a little USB connected box that's designed to hold a laptop HDD. I just tried it out and it doesn't appear to be working, or it is working and I'm just not using it correctly.

I'm trying this on my Vaio laptop where the memorystick reader shows up as /dev/sda. When I plug the USB device in, I see ..

hub.c: new USB device 00:14.0-2, assigned address 9
WARNING: USB Mass Storage data integrity not assured
USB Mass Storage device found at 9
sda : READ CAPACITY failed.
sda : status = 1, message = 00, host = 0, driver = 08

.. where I would have assumed it would use sdb? Or, is the sda message a bit of a red herring? (Considering there's no memorystick actually in the machine)

scsi_info says

vaio:/home/ottaky # scsi_info /dev/sdb
SCSI_ID="0,0,0"
MODEL="IBM-DARA -212000"
FW_REV="0811"

Which seems correct .. but the morystick reader seems to have the same ID ..

vaio:/home/ottaky # scsi_info /dev/sda
SCSI_ID="0,0,0"
MODEL="Sony MSC-U03"
FW_REV="1.00"

Is this normal?

Anyway, trying to mount /dev/sdb1 always returns a "not a valid block device".

Any ideas?? ;-)
