I currently own a Seagate 500GB External Hard Drive. I want it to be able to serve as a time machine backup and file storage. How can I do that?

The easiest way is to partition the drive, creating two volumes, the first can be used for TM, the other for your file needs.

I'm a rolling stone.
I have to disagree with Maflynn :p, there is no real advantage of partitioning, actually I think it creates a problem, you have to decide how big the partitions need to be now, if one grows to big you run into problems, not so if you don't partition, and yes, it works.

If I do 2 partitions what should the formats be?

If I chose not to partition them, time machine will create a folder by itself?

The advantage is that you keep the backup sparseimage logically separate from your files. I agree there is no technical advantage since we're talking about the same physical drive

It's worth pointing out that the "file storage" files will need to be backed up to ANOTHER physical device.
You can't backup files to the same device, because when it fails, you've got nothing to restore your files from.
