    I am answering Ekse's question. Tomorrow, Monday, 14/12/2008, I will test the device with its power adapter on another computer as you suggested. The device is not very old. It was purchased in October 2007. Thank you for your help.

    Regards,

    One of the first things I did was what WIZ suggested, un-connect all the leads, then reconnect. I did not work. I have now taken the device back to the shop to fix it under warranty. Thank you for all the help you gave. One last question: For a really dependable external hard drive, what brand would you advise. Regards. rthu

Hi,

Some LaCie drives now ship with the LaCie Setup Assistant installed.The LaCie Setup Assistant will automatically prepare your LaCie harddrive for use on your system. For instructions on the LaCie SetupAssistant please see our FAQ here. Ifthe LaCie Setup Assistant is not provided on the drive, depending onthe model, your hard drive is formatted Mac Extended (HFS+), WindowsFAT32 or Windows NTFS.

  • If the drive is formatted Mac Extended, you will not need to initialize the drive before use unless you wish to partition it.

  • Ifthe drive is formatted FAT32 it will mount on most Macintosh systems.You will want to keep the drive in the Fat32 format ONLY if you aremoving it between a Mac and a PC. If you plan on only using it on a Macyou will want initialize it.

  • If the drive is formattedNTFS, it will mount on the latest Mac OS, but it will be read-only. Youwill need to initialize the drive before use.
  • To determine whatformat the drive is in launch Apple’s Disk Utility. The Disk Utility islocated in the Utilities Folder in your Applications Folder. Launch theDisk Utility by double-clicking on it. All connected hard drives willbe listed to the left. The mountable partition(s) of each drive willshow beneath it. Highlight the partition of the LaCie drive and look atthe information at the bottom of the window.

      Here is the pic:




      To Initialize or Partition the DriveNOTE: Initializing or partitioning the drive will erase all data on the drive.
      If you wish to re-initialize or partition the drive in OS X, you will use Apple’s Disk Utility.
      NOTE: While various versions of the Disk Utility will be slightly different, they all operate similar to these instructions.
      While
      Apple provides an “Erase” feature, we recommend using Partition to
      initialize the drive, even if you are not setting up partitions. Using
      the Partition utility will verify that all previous formatting
      information is deleted before initializing.



      1. Highlight
        the LaCie drive in the list to the left and click on the Partition Tab.
        (You will not get a Partition Tab if the mountable portion of the drive
        is selected. You must select the drive).





      1. Under “Volume Scheme” click on Current and change to the number of
        partitions you wish to create. If you do not want multiple partitions,
        select “1 Partition”. Do not leave as “Current”.


      2. Highlight each partition to change the Name, Format and Size.

      Select the Volume Format. NOTE: Mac OS Extended will be the best
      format to choose for the external drive. To change the Volume Format,
      click on the chosen format and select another.



      NOTE: If the only format showing is “MS-DOS”, click on
      the Option Button on the bottom of the window and choose the selection
      referring to Apple. (Various versions of OS X will give different
      selections: Apple Scheme, Apple Partition Map, etc.)


      1. Name the partition(s). This is the name that will show up under the drive icon on your desktop.


      2. Check
        the box to “Install Mac OS 9 Disk Driver” if you need to use the drive
        on a computer booted from OS 9. (If you are unsure, check the box).



      3. After making any changes necessary, click on the Partition Button in
        the lower right corner of the window. When the process is complete the
        partition(s) will show under the drive.
      The partition(s) should show on the computer desktop and is now ready to use.

    Hi,
    The drive may have a fault, I suggest you try the drive on another computer and see if it functions there, if the drive doesn't function on another computer its very likely faulty of if the drive uses a external power adapter the power adapter may not be providing the drive with enought power to function.
    Hows the warranty on your hard drive how old is it? 
    This is just a start report back to me thanks

    Lacie Hard drive not recognized


    If your computer recognized the hard drive before you have installed your last operating sistem(s) that can be the problem. Your operating sistem or BIOS is not seeing your hard drive any more. Installing a new operating sistem is going to solve your problem but try another one, not the operating sistem you used until now.
