external Hard drive crash

Hey I have a problem with my hard drive that I am really stumped to fix. I believe it was formatted to FAT32, but am not positive, it may have been NTFS. Anyway, it is a 500GB external Lacie usb2.0 and a few days ago, I turned it on and it said that the drive was unformatted. it just says that there is 0 bytes of space on the drive and it is in RAW format. I have tried it on 3 different computers, all with the same result. I really need some of the data on that disk, and really want all of it. Is there a way to get it back, any way to recover it, or do you think that it is just gone. Thanks for advance for your help.
