Well, sort of; not quite.  When you do fdisk -l on the devices, fdisk shows 
you the device name (/dev/sda, in this example) and then the partition 
number, directly appended to the device name.  As it happens, this 
(typically) correlates with how the kernel creates the partitions; though 
it doesn't *have* to.

Mount was just telling you that the device node sda1 in /dev didn't exist.  
It should exist, though, after replugging the device in... if you need to 
create it really quickly, you can just do:

 # mknod /dev/sda1 b 8 1 

That will temporarily give you that node, until you can figure out why its 
not already there...
