    I partitioned my external hardrive to use for time machine - most of the space I want to use for time machine, and the rest to use for whatever. However, I don't think I formatted the hardrive correctly. When I plug the hardrive into a pc, it won't recognize it.

    Is there a way to do it where I can use time machine on one partition and then use the other partition as a storage device that can be used with both a pc and a mac? Your help is appreciated!

    Did you make the partition for Windows FAT or HFS? Windows cant read HFS without a program called Macdrive. For native windows and mac read/write support the partition must be as FAT

    The drive is formatted HFS which is what you need for Time Machine. This format is unreadable on a Windows PC without third party software.

    Time machine partition table is either GUID (GPT) or APM. Neither is accessible on 32 bit MSwindows, so Time Machine drives live only in the Mac world with sharing with MSwin world not possible (at least for now). See
    for some more background and some exceptions.
