I have a LaCie hard drive attached to one of the USB ports on my airport extreme. I don't use it for back-ups, as I use an iomega drive for that, but simply storage of extra files. The odd thing is that I can't seem to search the drive over the network from my laptop. Yet when I connect the hard drive directly to my laptop, it works just fine. I have enabled file sharing in airport utility. Also, I just noticed that while my Epson printer is connected to the other port and I can use it just fine from the print menu, it doesn't show up under the printer menu on the airport utility. This drive is mac-formatted, but I thought I'd pose this question here, as many of you seem to be knowledgeable enough to figure this out. Any ideas? Thanks!
