Having a problem using my portable hard drive?

Its a new hard drive, about 1 week old and has been working fine until now. I connect it through the USB and my computer seems to recognize it. I see it in my Device Manager and under Disk Management also. However, When I first got the drive I Re-named it to "Rons2" but It's calling itself Local Disk now. Im assuming there is some problem with the computer reading off of the drive. Any ideas for help? I can give anyone more details about this if they wish to know.

P.S. I have already moved quite a bit of files onto the drive so I REALLY don't want to re-format it. I know that if I want my files back I might have to take it back to a data recovery group but that will cost alot of cash and there might be another way to fix this.

Please anyone help me I would really like to get those files out.
