    I have a brand new Mac Pro with 5 hard drives installed. My "MacHD" home drive is a 1TB that came with the computer and I installed 4 more Samsung 2TB drives into the available bays plus rigged up a bay in one of the CD trays areas. These drives are named "Drive 1/2/3/4"

    Yesterday I hooked up a Lacie Minimus 2TB external to my computer for the first time and went through the setup and formatting process to make it one large drive on the mac. Then I named the drive "Portable 2TB" and copied over one large folder (1.15 TB) from "Drive 1" on my computer to the "Portable 2TB" Lacie drive that I just hooked up. It took 4 hours and then I shut down my computer for the night and everything seemed OK.

    This morning when I turn on my computer, my Samsung "Drive 4" internal drive somehow thinks that it's the Lacie "Portable 2TB" drive. ALL THE INFO THAT WAS ON "DRIVE 4" is gone and it's just that 1 large folder that I copied over to the external drive yesterday. What was yesterday called "Drive 4" on my desktop is now named "Portable 2TB" and there is even a Lacie logo! I go into disk utility and it still says it's a Samsung drive.

    My question is: what is going on here? Is it possible that the Lacie setup process I went through yesterday formatted the wrong drive on my computer? Did it reformat "Drive 4" instead the Lacie external like it was supposed to?

    Another clue: when I attached the external again this morning it made me go through the formatting process again, as if I had never formatted it yesterday and never copied that huge folder over to it...

    You should probably take a screen grab of Disk utility and explain. I just got lost as to what is going on here. HDD's just don't rename themselves.

    Also - in terminal do a: "ls -lah /Volumes" and post the output.
