Cannot Change Permission of External Hard Drive

[ktalebian]

Hi there,

I have a MBP running OS X 10.6. When I connect an external LaCie hard drive to my mac, I cannot copy files to it.

I went to "Get Info", and opened the "Sharing & Permissions". It says "You can only read" and I cannot change this. There is no lock key or anything for me to click.

What do I do?

Thanks

Can you check the option: "Ignore ownership on this volume" ?

It would be at the bottom of the Get Info window.

What is the format of the filesystem on the LaCie?

Finder --> select and Get Info --> General --> Format: ????
