I really want my NEO jukebox (it's essentially a harddrive) to work under linux and I think it's something simple to get it to work. I am running Mandrake 9.0 and it already has all the usb mass storage stuff in it. I also run two scsi harddrives (/dev/sda $ /dev/sdb) How do I figure out where the mass storage driver places the usb harddrive? I have tried to mount it under /dev/sdc1 and the error mesage says that:

mount: special device /dev/sdc1 does not exist

Please help me out, I have been wanting to get this thing to work for a while. Is there a utility to see where the mass storage device driver places the partition? Any thing would be helpful.

Have a look at the logs ('tail -f /var/log/messages') and see what it spits out when you plug the drive in. If it is a usb mass storage device and if it is recognized it should show you how it was assigned.

will it tell me which /dev it attaches to?

Assuming you have everything set up correctly and it's all working, AND
you are running devfs:
If you do a:

cat /proc/scsi/scsi

You'll see something like this:

Host: scsi1 Channel: 00 Id: 00 Lun: 00
Vendor: NIKON Model: NIKON DSC E995 Rev: 1.00
Type: Direct-Access ANSI SCSI revision: 02

The important thing is the "Host:" line, as that tells you where the device
is connected.

In this case, it's connected to SCSI1, 0,0,0. This means your device is:

/dev/scsi/host1/bus0/target0/lun0/disc

<EDIT>
You may not need to be running devfs for this to work, but it's much
easier to figure this out. . .

That is what I got. My neo jukebox has a standard 2.5" 10 gig harddrive in it. Is this what is supposed to happen or is my neo jukebox not being identified by the kernel? Like I said before, the dmesg says that it loaded the usb mass storage device,

I'm seeing two Seagate hard drives, one Plextor CD-ROM drive and
something else that isn't recognized by the SCSI driver. The two hard
drives are on the same controller, so I'm guessing that they are both
installed within your box. The unidentified device is probably your neo, try
mounting that with:

mount /dev/scsi/host1/bus0/target0/lun0/disc /mnt

[root@localhost mrsolo]# mount /mnt/neo
[mntent]: warning: no final newline at the end of /etc/fstab
mount: special device /dev/scsi/host1/bus0/target0/lun0/disc does not exist

The above is what I got when I typed in that location. What gives? I get that error everytime I attempt to mout it. I know Mandrake 9.0 is loading the drivers for a mass storage device, I just can't seem to mount it because it doesn't have a /dev location that I know of.

Actually, I don't think the driver is loaded at all. Do you think I need to recompile the kernel?

Can you do a:

ls /dev/scsi

Also,

cat /proc/filesystems

This will tell you whether you're using devfs. If not, I'll need to think back
to the dark ages and try to remember if there is an easy way to figure out
what device names are used for which controllers.

That's a dump from the kernel, and while I don't actually know exactly
what it means, you can either do a lot of web hunting to find out (and in
the end probably submit a bug report to the SCSI or USB maintainer), or
first try recompiling your kernel, which will take a lot less time, but you
won't learn as much. . .

If you are going to recompile your kernel, read up on devfs, it's freakin' cool
and very useful, but also can be dangerous if you don't make sure you've
done everything correctly.

Also,
Post your /etc/fstab. There's something funky about it (from the error
message you posted above).

Here is my /etc/fstab listing:

/dev/sda5 / ext3 defaults 1 1
none /dev/pts devpts mode=0620 0 0
/dev/hdb /mnt/cdrom auto user,iocharset=iso8859-1,codepage=850,noauto,ro 0 0
/dev/scd0 /mnt/cdrom2 auto user,iocharset=iso8859-1,codepage=850,noauto,ro 0 0
/dev/sdb1 /mnt/cheetah ext3 defaults 1 2
/dev/fd0 /mnt/floppy auto user,iocharset=iso8859-1,sync,codepage=850,noauto 0 0
none /proc proc defaults 0 0
/dev/sda1 swap swap defaults 0 0
192.168.0.199:/mnt/share /mnt/disk nfs user,exec,dev,suid,ro $/dev/scsi/host1/bus0/target0/lun0/disc /mnt/neo vfat defaults 1 2

That last line looks bad.
I don't know if it's because of the way you posted it, but I suspect it's because
it's like that in the fstab (the error message above indicates that you have a
bad line in your fstab).
Try removing the reference to neo et al. ($/dev/. . . /mnt/neo. . . defaults. . .)
and mounting with the command:

mount /dev/scsi/host1/bus0/target0/lun0/disc /mnt/neo

(do this as root)

Though I suspect this won't work because you probably don't have
usb mass storage correctly installed in the kernel.
