I did say 'most likely'
There has been another poster that has used a drive powered by one
Iyonix port also.
In my case, my friends Iomega drive spun up, but repetitively
clicked.
IMHO I dont think it is worth operating one close to the wind,
even if it appears to be OK. But then I haven't been pushed
into the situation as my drive as separate power.
I think on a modern sata type you could run a flat sata power cable
through a crack or slot in the case.
