Can you post a copy of /etc/fstab?




Here it is.

/etc/fstab:

The device shows uip in the devices list in a file browser, but still
gives the same errors when attempting to mount.


What do you mean by the "devices list"? If it shows up, doesn't that mean
it's already mounted? What happens when you click on it? Can you view the
properties of the device?



I plugged it in to my
other Ubuntu box, also running Hardy and it mounted normally. Whatever
the problem is resides on this machine.


It does. The error is about the mount point. In the first column of
your fstab, you can see several devices/partitions which are normally
available on your computer. The second column lists the position (mount
point) where they will be added to your filesystem. Somehow, your
computer tries to add the USB-drive at an illegal position.
You could take another look at /etc/mtab after you plugged in the drive,
and see if sdb1 is listed there. (Proably not, if the mounting fails.)

Another option would be to check if you have a udev.rules file with an
illegal rule for the USB hard disk. Check it by typing

cat /etc/udev/udev.rules

(udev.rules is a bit like fstab, but then for hotswappable devices)



Result of that is:
jim@JimsBook:~$ cat /etc/udev/udev.rules
cat: /etc/udev/udev.rules: No such file or directory
jim@JimsBook:~$

/etc/udev contains a subdirectory 'rules.d' which contains numerous
files, many of which I looked at but none of which seem to have my
device in mind.
lsusb does show the device on the first line:
jim@JimsBook:~$ lsusb
Bus 005 Device 004: ID 0d49:7350 Maxtor
Bus 005 Device 002: ID 0ac8:c002 Z-Star Microelectronics Corp.

Still mystified.

I have read that ubuntu (and pretty much any linux running 2.6.18 and
newer) has this power conservation feature that limits the power output
to the usb. A normal usb will output about 5 volts of electricty. I
believe the power save feature cuts it in half, so a few devices, such
as wireless cards, external hard drives, thumbdrives, and a few other
devices may not work. What i ended up doing to get around that was to
create 99-custom.rules in the /etc/udev/rules.d directory. I dont think
that showing mine as an example would be a good idea because mine is
used for my usb wireless device

--cj




Maxtor gets around this by supplying a "Y" connector which connects the
device to 2 USB ports, one for power and the other for power and signal.
Still won't mount, gives original error msg.

Many thanks

Jim
