Sharing GPT formatted drive on network

[Ambiguous]

Is anyone aware of any restrictions on sharing an internal gpt-formatted hard drive on a network? I have a 3TB hdd installed in my main pc running windows 7 (the drive is data only, im booting from another), but am getting a permission error when trying to access the drive on my other windows xp computer, and my macbook pro. Is the gpt format exclusively read by Win7? The drive is shared (just like a couple other drives installed) and the others are all accessible on the other computers...

Thanks

As far as I know it shouldn't be a problem. I would think that the host OS (win 7) would handle all the reads/writes to the drive. Double check the permissions on the drive.

Yeah the permissions are all fine, same as the other two data drives in the pc. But only this one wont share...

Well, don't know about the mac, but XP should be able to read the protective MBR of the drive.

Q. Can the 32-bit version of Windows XP read, write, and boot from GPT disks?

A. No. The 32-bit version will see only the Protective MBR. The EE partition will not be mounted or otherwise exposed to application software.

I don't believe that applies when connecting via network share. The Mac and the Win XP machine should be able to connect using SMB if everything was configured properly on the share.

When connecting via share the local formatting should not matter since the smb protocol handles the inbetween.

I don't fully understand the exact workings, but I can say I've got several macs, a few ubuntu machines, plenty of win machines 32 and 64bit Win7 and XP connected to a 30Tb volume without issue which is running on a Win 2008 R2 machine.
