What Happened to Other Two HDs?

Niel, here is a screen shot of the Utilities folder. What should I do next?

Dead. They were working just yesterday. How do I bring them back to life?

Niel,

1. May 9, 2013, I bought a G4 QuickSilver Mac with only one hard drive on ebay. Main Disk was named "WD1200 Boot Drive." Worked great.

2. May 13, 2013, I installed a second hard drive to the one mentioned above, and named it "2nd Maxtor Boot Drive." Worked great.

3. May 21, 2013, I installed a third hard drive, and name it "3rd Hitachi Boot Drive." Worked great.

4. May 21, 2013, after I installed "3rd Hitachi Boot Drive," and used it as the "Startup Disk," I copied all of my external hard disk data (named "Mac Companion") to "3rd Hitachi Boot Drive."

a.) I then began moving to trash/deleting the data from "Mac Companion."

b.) Because data being trashed/deleted from "Mac Companion" was taking so long, I quit the procedure by just pulling the plug on the Mac while it was still under the control of "3rd Hitachi Boot Drive."

c.) I didn't "Shut Down" by the book.

The next morning, today, when I booted up, the only hard drives showing were:

1.) 3rd Hitachi Boot Drive, and

2.) Mac Companion

The other two hard drives did not show up on the desktop; nor did they show up in the Utility folder.

All the drives were installed correctly. All drives were functioning correctly. There were no problems until I "shut down incorrectly."

What should I do next?

Thanks for all your help, Niel!!

I just physically uninstalled the two hard drives that weren't showing up on the desktop. I removed the two power cords to the two hard drives; I removed the two data cords; took out the two hard drives. Then I re-installed the two hard drives as if they just came off the factory floor. I re-connected the two data cords; I re-connected the two power cords and booted up. All the hard drives are now working perfectly!!

Thanks a million, rccharles!! I can use all the advice I can get!!
