    Just to seperate this from the previous thread, but I noticed when I added
    a SATA drive as slave it appears as I: (or i:) on the drive list.
    I was puzzled why this was when I fist saw this,.the only theory I have goes
    this. I have my boot drive c: and it's recovery partition d: (on a side note
    it is odd
    perhaps that d: appears before c: when evey you display the partitions on
    the drive.
    Then I have the DVD drive e: and I have had USB drives on g: and h:
    so maybe i: was just the next letter available when I cloned the drive,
    I am pretty sure I had no USB drives connected when I cloned the drive so
    a bit odd to me. It is lilke windows remebers which drives have been

    Anyhow it's probably a bit of a red herring regarding my SATA boot ptoblems.

    Driver letter usage is recorded in the Registry.

    If you use Regedit, there is a key "\DosDevices\C:"
    in MountedDevices. And you can see all your drive letters
    in there. Now, I've *never* used the letter "O" for
    a drive, and in honor of that fact, there is no
    "\DosDevices\O:" showing in the list of keys there.

    Thanks for that!!

    But as you probably already know I have cloned using Acronis and it worked,
    my drives are :C and D: as normal!!

    Maybe I will try cloning again to the SMART error drive to see what happens?
