URGENT HELP: Hard Drive Wont Mount

[Melodeath]

I have an external hard drive (NTFS) hooked up via firewire to a firewire audio interface, hooked up to my Macbook Pro with OS X 10.6.4. I accidentally turned off my firewire interface before ejecting the hard drive. (I have done this before, it's hard to remember I have my hard drive on sometimes, and nothing bad has happened). When I turned the hard drive back on, the mac says "the disk you inserted was not readable by this computer." I can pick "Initialize..." "Ignore" or "Eject"

If I click Initialize, I can't repair the disk or anything because it is NTFS.

I tried booting into Windows 7, and it does not recognize the drive either.

Please help me.

EDIT: I also tried using USB instead of firewire, but I have the same problem

If you put your ear next to the hard drive, do you hear any odd noises like a clicking? If you don't have a backup of the data, you might consider investing in diskwarrior.

No, everything sounds normal with the drive. Just the usual spinning sound.

In windows, it says I need to initialize the drive, but I am worried that doing so will erase my data (assuming it's still on the drive)

If Windows recognizes its connected, try using Western Digitals DiagnosticTools here: just do a Scan of it see if spouts out any errors.

Also try HDTune:

Would those programs write data onto the drive? I don't want to write any data on the drive, just in case I have to do data recovery
