Using External Hard Drive as Time Machine and Storage

Format the time machine portion to HFS+ and the rest to FAT32.

 

I disagree. With a FAT32 partition, your file size will be limited to 4GB. That is, if you want to transfer a single file that is larger than 4GB between Mac/PC, you're SOL.

Format the Time Machine partition as HFS+, then the remaining partition as NTFS. Download NTFS 3G on your Mac (free) to gain both read/write priveledges. Voila.

 

nope7308- May I suggest that you should give complete formatting instructions to the OP with advice like you offered since you cannot format as NTFS within the Mac's Disk Utility as you can with FAT32? And as a heads up, NTFS-3G by itself is worthless if you don't have MacFUSE installed as NTFS-3G is just a driver for the MacFUSE filesystem.

To the OP- Do you think you have any individual files larger than 4Gb? Few people do except for some that are involved in huge video projects, so FAT32 is fine for the majority of people particularly because it can then be read from or written to with a Mac with no third party utility software being required. If you do have any, then formatting to NTFS is the only way around that.

BTW- If you do choose to use NTFS on the second partition after using your PC to format the partition, you will need to download and install two free utilities (linked below) for your Mac to allow it to write to your NTFS space. It does not need any software to read from the NTFS space.

Those two pieces are:

MacFUSE- the filesystem
and
NTFS-3G- the NTFS specific driver that works under the MacFUSE filesystem

Be sure to install MacFUSE first, then install NTFS-3G. Restart your Mac and you will then be able to write to the NTFS volumes if necessary.
