I'm trying to access my WD Passport using firewire 800 on both Windows & Mac.

The current situation is:

I have partitioned the drive through Mac Disc Utility with three partitions.
1. Time Machine
2. Mac OS Extended (Journaled)
3. MS DOS (FAT32)

I can access all partitions when running the MAC OS.
However when using boot camp to lunch Windows 7 Ultimate (64bit) I cannot see the drive.

I've tried going into windows disc manager and can see the disc as an unallocated drive with no partitions.

What I want to achieve is to have the one external drive like this;
1: Time Machine (for MAC backups)
2: A partition for storing my MAC files on
3: A partition for storing windows files on (accessed while using bootcamp).

All without losing the existing backups on the drive.

Sorry I'm a newby to MAC (but love it :D) any help appreciated.

you should have no issue at all seeing it however what if the two were FAT32? because mac will see both.

I have an external running on my network similar but everything can gain access.

My guess: You managed to partition the drive using Apple Partition Map (So that Mac OS 9 can boot from it :rolleyes:) instead of MBR or GPT. Since you are using W7 64 bit, GPT should be preferred.

This happened to me once....

As neenja mentions, you should be able to use CCC or something like it to image the data on the drive, repartition and replace the data. There is no non-destructive way of changing the partition scheme that I am aware of.
