Networked PC Cannot write to Boot Camp when it's inactive

[pommephone]

No problem reading and writing to my Boot Camp Partition from networked PC when it's active (when Boot Camp Windows 8.1 is running). When Windows on Boot Camp is shut down, I can access and read all files and folders on Boot Camp partition, but cannot write. For instance, if I try to paste a file, I get a Windows notice that the drive is read only.

Wondering if there's a way around this? For instance, on my dual boot (Windows 8.1 and Windows 7) PC I can read and write to the inactive OS from the active one.

This is not a permissions problem,since I can read and write from network PC just fine- as long as Boot Camp Windows 8.1 is running.

That is expected behavior. The Mac OS by default can't write to NTFS volumes, so a networked PC won't be able to either. You can get around this by installing a 3rd party utility that will allow read/write on NTFS volumes on your Mac.

Why is this the case only when Windows/Boot Camp is inactive? No problem reading/writing to the partition from a network pc when Windows/Boot Camp is running.

Because when it's running Windows, it's not running Mac OS, and of course the boot drive is read/writable by Windows.

I know- I'm slow, but I still don't entirely get why a networked Windows PC can't write to the NTFS Boot Camp Partition. How does OS X come into play?
