Hi,
Generally speaking, to access and setup the CF card properly, you really need OS 3.1 or higher, then use the HD tools to select, define and partition the CF drive. I haven't used OS 1.3 since the early 90s, so I am worthless in that regard.
You will benefit from a book or manual about using the Amiga; many are free downloads from archive.org. Questions cost nothing, but be prepared for delayed, and sometimes wrong, answers.
