I have Lacie Rikiki Go 500GB, when the first format I set it with Mac user. Now I want to use for both Mac/Window. Pls advise. Thanks

well we all have had that problem I have sent back items that were bad when I toke them out of the box before

Replacement cables are available for purchase on ebay for under $5

format from my compuer disk management.

A small, flat screwdriver should be OK

just run disk management and enable entire volumne on the Lacie

Your hard drive is most likely dead, you need to call the manufacturer and have them send you a replacement, the warranty should cover this.

I have the same problem with my powerbook G4!!
do you allready haver a solution? i think the power is just not enough!

This way it should work...
Connect your drive to the computer...
Go to: Start > Control Panel > Administrative Tools > Computer management.
A new window will appear...
Select Storage > Disk management on the left of the window.
Now you will see the different drives that are connected or part of your system.
One of the drives listed there is your LaCie, i think you'll recognize it by name...
Right-click on it, and select 'format'
In the new window, select the new volume label (as you like it), the file system (use NTFS), and set allocation unit size to default.
Make sure 'Perform a quick format' is not checked...

Then click OK. Your drive will be formatted now... Don't interrupt the process

You need to make sure the drive is formatted for the PC. The Mac will read and write to a FAT32 partition, but the PC cannot see a Mac formatted drive as you have seen.

The only problem is that there is a 32Gb limit per partition for FAT32 drives.

It's not ideal but it's the best you can do easily.
