recovering data

I have a hard drive which used to be a shared drive (/yard) in a small server. I thought it was empty and fine to be reinstalled, but know I think it might have had some important data on it. I have reinstalled, and maybe even reformatted this disk, but it has not been extensively written to. I have messed around with it. Any chance of recovering this data? If I have to send the disk out for revocery, I always hear it's expensive, but how expensive is it? thanks __________________________________________________ Do You Yahoo!? Yahoo!
