At dinner tonight, a friend of mine said he doesn't think twice about installing a new drive with the Mac Pro powered on.  He has no reservations about it.  He's done it and it works for him.  It doesn't make me at all comfortable and I'm  getting ready to install one.  I will have the power off.  Does  anyone agree with my friend?

    I don't know whether anyone agrees with him, but Apple doesn't agree.

    As Linc Davis has said, "live plugging/Unplugging" NOT RECOMMENDED!

     

    The Mac Pro uses drive connectors that will power up the drive in a predicatble fashion if it is plugged/unplugged "live".

     

    But Mac OS X is unprepared for drives to come and go in this fashion, and even if it did no electrical damage, it may wipe out the directory on one or more drives or crash your Mac.
