External Hardrive Error. Files Wont Transfer

[spooks]

Im useing a LaCie external hardrive, connecting through Firewire 800 on my iMac running OSX 10.6

When I connect the drive, it mounts fine, and I can read files, run applications and watch videos that are on the drive with no issue. However, whenever I try to put a file on the drive or take one off I get the message:

"The operation can’t be completed because an unexpected error occurred (error code -8003)."

I tried to open disk utility to get a closer look, but it just crashes before it finishes opening. This is happen wether or not the external is connected.

No idea whats going on here, and I cant find anything relating to externals when i look up this error. Ideas?
