Theory: One of the 2 hard drives has degraded and will most probably die completely. The Mac System has slowly had more problems in reading the Lacie Disk taking longer to transfer files. Finally the Mac gives up and stops recognizing certain Directories. Checking the Lacie for errors only makes things worse.

Your data now seems LOST !!!

• step 1: Tear apart the Lacie enclosure, you will find 2 identical Maxtor 6H500R0 hard drives.
  -You will find 2 phillips screws at the rear of the Lacie unit.
  -Remove the back plate then you can slide the hard drive assembly from the front.
  -You will now see the 2 hard drives.
  -On the bottom you will see the mounting screws, label the drives Master and Slave before removing.
• step 2: Duplicate each hard drive individually to similar destination hard drives (for safe keeping).
  -The jumpers on the drives will be set for Master and Slave
  -Follow the diagram on the drive labels to set the hard drive to MASTER for cloning.
• step 3: NOTE: I like HDCLONE Hard Drive Recovery Software from Data Recovery Labs, it works well for cloning hard drives with bad sectors
• step 4: Once you have cloned as much of both drives as possible, you should be able to install both cloned hard drives back into the Lacie BigDisk Extreme and retrieve your data.
  -Making a second clone is more effort but will protect your data should something go wrong during the Recovery process.
  -Note: don't forget to restore the jumpers back for correct Master and Slave functionality.
• step 5: If your drive does not mount, you can now use all Disk Repair Uitilities in MAC or Diskwarrior works well also. If the structure is too damaged, R-studio or File Savenger from QueTek work good enough to get critical files or Pictures.
