None of my external drives will show up when plugged into my 11" air. They spin, but dont come up
Is it a power issue? Or is this normal?
 
my 11" macbook air is able to power an external optical drive without power suply and the disk shows up as normal.try mounting the via the terminal
 
weird it should at least show up. i'd say you mount it in the terminal if nothing happens then it may be a disk failure. but of course if it works on other machines with windows or linux on them then it truly is a weird issue.

edit: did you try both ports? and did you try to plug it in with the mba charging?
 
both times the drive was plugged into a MBA that was charging
tried both ports
how do i mount with terminal?
 
Ok so my linux use has apearently spoiled me. You should see the disk in disk utilities if not then i think you should try it with a different computer. Ask you friend or something.
 
Yes, but the drives work in my MBP... so I am wondering if anyone else had this problem

Have you tried it on BOTH of your MBA USB Potts? I think that only one of them is capable of supplying power to an external device.

EDIT: At least that is what I've seen on my 11.6" MBA.
