You would install Macdrive (or equivalent) on your PC to be able to read/write and format Mac formatted drives in the PC (that's what I use).
However.... if you happen to be staring at the Black Magic web site home page today you may just happen to notice there is an annoucement for "ExFAT" support for the Hyperdeck "coming in September". That apparently will mean the drives will be compatible in both PC Windows and Mac environments.
