I have tried connecting it to my computer using Firewire 800 and usb and it doesn't show up. I do see it in disk utility and it says its fine after I run diagnostics. Any ideas?

    Can you mount it to your desktop using the mount button in Disk Utility?

    Did it work before? What brand/model is the drive? Do other external drives mount?

    I wonder if the enclosure has gone bad--WD makes great drives, but I've read a lot about the enclosures failing. It may be worth trying the drive in a different enclosure.

    If you're still under WD warranty, it may be worth taking this up with them and see if you can get a new drive out of it.

    Good luck!

    I'm having the exact same issue. For the past few months, my 1TB WD external would randomly eject itself from the system and I couldn't figure out why. I scoured all forums and still couldn't find an answer.

    Today, my MacBook Pro is now not even recognizing the external hard drive when it's plugged in via USB. I can seem to find any firmware updates or anything that could be the culprit behind this.

    The drive may have GPT Protection enabled. Try instead to partition the drive by opening Disk Utility, select the drive and select the partition option, then select 1 partition and switch it to the 'FAT' format. After that you should be good to go. Hope it works. If not, see if someone with a different system (Windows or Linux) can help. (but if it is GPT Protected they'll have to do something similar to fix it). Hope this helps.
