[SOLVED] Can't copy full sized files from Mac to external hard drive - help?

[katec7]

Every time I copy any files to the My Passport, it shrinks them. For example, I coped a 20MB jpeg file to the My Passport, but it showed up on the external drive as only 171 bytes!!! And it couldn’t be opened either because the file was apparently damaged according to the error pop up box. I have a MacBook Pro that is fully up to date and I have used several external hard drives from Seagate with no issues using the NTFS software but this one is just so frustrating. I’ve reformatted it but what’s the point of backing up files on it if they’re all tiny and unusable?
Has anyone else had the issue? Any fixes?
Thanks

A 20MB jpg cannot compress to 171 bytes.

I would think you are copying the wrong thing. A shortcut, instead of the actual file.
