Windows external HD compatible with Mac?

Seagate Freeagent go hard drive - 500gb...

Specs: Mac
Basically I'm getting a Macbook Pro soon. I'm gonna have Windows 7 on my macbook as well and I'm primarily gonna use the Hard drive for the windows partition. That is why I'm asking you if it is possible if I could "format" the HD to whatever format it requires to be able to Read and write on both Windows and MAC OS.

I've heard some about FAT 32 but, I believe there are some bad things with that format, but I'm really not sure. Thats why I'm asking you gys for help.

Thanks alot in advance!

A Word of caution. The systems can recognize the hard drive
but not always the partitions and files on it. I had a friend who
had backups of Windows files on USB hard drive and took it and
a MacBook to an Applestore to repair the laptop and told them to
backup the laptop onto the external drive. When she got it back
only the Mac files were on the disk. When asked about the
missing files they said the drive was empty.

@wizard-fred

That is because your friend forgot to mention that her HD was originally formatted in NTFS, a format not supported until recently on OS-X, and it is still not fully supported. The normal procedure is to hook the drive up, and format it in HFS+J or unix file system. NEVER bring your HD that you use to back-up files into a store and ask them to back up another computer onto the same drive, they will format and overwrite anything on it 90% of the time.

@Adio

There are no "bad" things about FAT32, it is a much faster and cleaner filesystem than NTFS is, it is also supported on more platforms than NTFS is. The only real down fall when it comes to FAT32 is the 4gb limit. However, as far as I know, Windows 7 does not support booting off of a FAT32 partition. Your best option would be to just split the HD, half formatted in NTFS, and half in HFS+J, or unix filesystem.

I am partial to HFS+ and HFS+ J., but since you have an Intel mac and have no way of running legacy OS-9 apps natively, just install the unix file system.

And is the "Unix file system" just called "Unix file system" in the Disk utility place where I format my HD?

It is called UFS I believe.

And you said I should format it to UFS not Mac OS Extended or Mac OS Extended Journaled, Correct?

Also, thank you so much guys!

In disc utility you need to format it as MBR with FAT filesystem. Then in windows format it as FAT32.
