troubleshooting ls120 mount problems

[ChadDavis <chadmichaeldavis@gmail.com>]

I need some advice in troubleshooting mount problems.  I've got al ls120 superdisk that I'm trying to mount.  I've installed it as the secondary device on my main ide channel, behind the boot hard drive.  

Here's what I've got in my fstab: 

/dev/hdb       /media/ls120     vfat    rw,user,noauto  0       0

And when I try to mount, with 

mount /media/ls120 

I get:

mount: special device /dev/hdb does not exist

So, I'm thinking the drive might be dead?  Or not being recognized?  

How do you troubleshoot such a thing?

Thanks for your help.
