Could be defective. Try swapping power cord and usb cable with know good ones. You could also plug it into a different (known working) usb port.

Good Luck

You don't mention which operating system you're on, and reformat instructions are specific to the OS. Also, I assume the OS is installed elsewhere, on another primary drive. If your OS is on this hard drive it's whole different kettle of fish.
It sounds like there is some corruption in your files, and the drive wants you to essentially erase them clean so it can clear up the mess and start anew. That is what is meant by reformat.
Please go to this link and attempt to follow the LaCie instructions to "Fix volume corruption"

If you have trouble with this, or don't understand how to go about data recovery, you will need to learn how to backup the entire content of the drive before reformatting it. In that case, I recommend you consider using a full image backup utility like Acronis True Image http://www.acronis.com/ or Symantec Ghost.
If you have current backups of the data stored on this drive, and understand how to work with them to restore the information to your hard drive, you can safely proceed with the reformat.
If this answers your question, please take a moment to rate this post. And by all means, if you're not certain about how to proceed, write back and I'll be happy to point you to some tutorials that can guide you through the process.

Just an idea. When you set pass words or any important information write all information in a note book and keep it in a drawer someplace where you will not lose it. When things change write the new ones down and cross out the old ones. I save a lot of head aches that way.

Pushing in the paperclip should unlock it, but if still jammed, may have to wreck drive by pulling off front of drive drawer thing. Maybe try putty knife to push cd down some of that's holding it from opening.

Replace perhaps, but repair is most difficult. The electronics are miniature and it takes special tools to do repairs.

Two ways this can go. If you are talking about the entire hard drive pulling it out and plugging the whole drive into another pc. Then you're fine

If you are talking about disassembling the hard drive and moving the disks inside. This is not something you can do.
This is what you will need.
1) a certified clean room surgical grade
2) tape
3) A matching drive/ hd board down to revision number
4) presision screw tools.
5) patience.

Or you will need to contact a professional data recover company.
