You may get away with one drive and 3 partitions

one for mac (gui)

one for windows (ntfs)

and one for sharing (dos fat)

I have an older Passport formatted NTFS that I used to carry files between my older Mini (OSX 10.6) and a Windows box and a Linux box.

When I got the 2011 Mini, that Passport wouldn't mount until I installed a third party NTFS driver.

This works fine: www.tuxera.com/products/tuxera-ntfs-for-mac/

Indeed, as I found out the hard way when I'd created a DVD ISO and then couldn't save it to my external drive Crying or Very sad

I have found it easier to have separate externals for each OS.

I have my Mac OS via firewire to a 1TB Lacie external (HFS+). I have a section for time machine and then also just drop files in the rest of the drive.

I also have a USB slot on my Mac to a separate 500GB external enclosure for Windows 7 (NTSF).

Both are 3.5 drives and 7200RPM hard drives. They are pretty snappy.

Works great for my purposes.

Sometimes wish this mac would crash, or screw up or break, so I can get a newer one and upgrade my OS , but "Oh Well".

I have a 500GB portable FreeAgent drive from Seagate. It's formatted FAT 32 for sharing. I know there are limits, but it works with both operating systems for free.

The best format to use is something called exFAT. It doesn't have the limitations of the old FAT format but it is still cross platform compatible unlike NTFS. Alternatively you can install NTFS drivers in OS X.

How do I learn what format is on my external hard drive? I bought it in 2008. It was supposed to be formatted for Mac. It must be because it works. My Linux computer can read the files I've stored on it, but it can't alter any of them. That is something I really need to address.

Run Disk Utility (It's within Applications>Utilities) and examine the drive. You'll see the format.

I see one line where it says "Partition Map Scheme: GUID Partition Table". Is that it?

GUID means that the partition is bootable.

When you look at the drive, there are two parts, the drive itself and then the partitions. The partitions are indented a bit and located under the drive. Likely you only have one partition (ie. Macintosh HD). Click on the actual partition it will have a Format: area.

p.s. Don't worry about clicking on things in the left pain of the window you can't do any modify or format a drive from there, you can only access information about your drives by clicking on them.

Thank you for telling me where to look. I clicked on one of the partitions and it says Format: Mac OS Extended (Journaled). All of the partitions say that. What does that mean?

The partitions are one for storage directly to the drive from the desktop via the Mac, Windows, or Linux. There is the Time Machine section, and then there is the Carbon Copy Clone section.

My goal is to be able to alter the files that are just regular storage using the Linux computer. Some came from the Mac and some came from XP via the Mac Drive 7 program. Right now it won't allow deletion or adding things into some folders. I don't expect the Time Machine backup or the Carbon Copy clone to be readable. It is that other section that I used to store files on that needs to be modifiable not just readable.
