HD icon missing but HD shows up in System Profiler

[Hombre]

Hello...thank you in advance for your response!

I left my Mac Pro on overnight to download a large file to find out in the morning there had been a power outage at some point.

The HD that was running at the time no longer has a desktop icon, nor does Disk Utility recognize it as existing, although it DOES show up in the System Profiler.

I have ALREADY TRIED:
1. Checking Finder Preferences to make sure Hard Drives etc are being shown. They are.
2. Left clicking the finder window and choosing 'Clean Up' to refresh the window.
3. Restarting several times
4. Trying the Finder menu: GO>Go to Folder> and typing in /Volumes
5. Trashing the file: com.apple.Finder.plist from GO>Home>Library, and restarting

NONE of those has worked.

I HAVE Disk Warrior, which does NOT show it as in it's Home menu, but DOES recognize it as existing within it's hardware check, and notes that it is functioning properly, but because it does not show up in the home menu, I cannot access it to rebuild whatever has been corrupted etc.

Does anyone know how to deal with this?

It sounds like when the power went off, your hard drive became corrupt. If Disk Warrior can't access the drive, it must be more serious than just corruption. Is the drive self powered or does it receive power from the USB port? Also, you may want to buy a good UPS to prevent that sort of thing happening again - especially to protect your Mac Pro.
