iMac i7 27" Cannot see WD external even though the drive was formated on this machine. Newer MBA 13" i7. Can see the drive w/o issue. ls /Volumes does not show the drive on the iMac. Disk utility does not see it. Light on the drive just blinks. Pulses. Seems, on occasion, to hang ny Eyetv. Any ideas, please and thank you?
Have you tried plugging it directly into the iMac as a test? This sounds like a USB hub issue to me. (I'm partly guessing based on the EyeTV reference.) Personally I find Western Digital drives to be more finicky and unreliable than other brands, but that's just my experience and yours may vary.
I have tried the actual USB port on the iMac. The USB port on the MBA works. I just get a slow blink when plugged into any USB port on the iMac. Thanks for trying. Skiph ---------- Explain please. What console? Attach how? You talking a terminal window and doing a mount command? Thanks for the reply. I know something is happening when I plug the thing into a USB port. My iMac becomes very sluggish. Would love to know where to go look to find out what is happening.
No, use spotlight and find/open console.app. With it open, connect your external hard drive and in the console, it should log what it's doing when you connect it.

WTH, over? It hasn't opened in weeks. I can see and manipulate data on the drive. Any clues? It "looks" bad, but it worked. Thanks,
