need suggestion, Common file system between MAC OS Mavericks and Windows 7 I have Mavericks on one HDD and Windows7 x64 on another HDD in same machine. Windows can't even see MAC partitions while MAC gains READ ONLY access to NTFS partition.

I want a robust and common file system for windows (data) partitions which can be accessed from MAC with full read and write support. My NTFS partitions are not huge as terabytes, in fact 50GB to 500GB max at the moment.

I have Googled and tried to analyze worthiness and reliability for the two solutions most commonly appearing
exFAT
NTFS drivers on MAC (paragon being recommended as faster)

I found cases with reliability issues and issues disk operations latency

I do have frequent power outages. I believe NTFS and HFS+ takes care and self heal upto some extent under such situations.

sigh! if MAC had native read/write support for NTFS this problem would have never existed for me. 

please suggest a solution
Enable ntfs write support in Mavericks

You can enable write support for ntfs in Mavericks. 

I have linked to instructions on how to do this, but the gist of it is to edit the /etc/fstab file and add a line for each ntfs drive you want to write to:

 LABEL=device-name  none    ntfs    rw,auto,nobrowse


changing "device-name" to the name of your ntfs drive.

This is a per device hack.



Third party software

Alternatively, there is a lot of third party software to give you full ntfs support, such as Paragon NTFS, or the open source NTFS-3G for FUSE which is utilized in the closed source Tuxera NTFS, or an old standard from Thursby Software, DAVE 



MacPorts

NTFS-3G and OSXFUSE are available for a free, package managed source or binary installation using the missing package manager for OS X, MacPorts. It is based off of FreeBSD's ports system, which is based off the finest package management system known to exist, of course I mean, NetBSD's pkgsrc. It won't let you down!

Installing MacPorts, NTFS-3G and OSXFUSE is simple enough once xcode (for Mavericks 10.9 xcode_5.1.1.dmg) is installed. Install xcode, and then enter these commands in Terminal.app :

 curl -Ok https://distfiles.macports.org/MacPorts/MacPorts-2.2.1.tar.bz2
 tar xf MacPorts-2.2.1.tar.bz2
 cd MacPorts-2.2.1
 ./configure
 make
 sudo make install #not war!
 cd ..
 rm -rf Macports-*
 sudo /opt/local/bin/port -v selfupdate
 export PATH=$HOME/macports/bin:$HOME/macports/sbin:$PATH
 export MANPATH=$HOME/macports/share/man:$MANPATH
 sudo port -vsc install ntfs-3g     # osxfuse is a dependency, macports will install it for you when you instsall ntfs-3g

MacPorts is worth getting to know as it is a mature package manager for OS X that maintains thousands of open source software commands, utilities, and applications. It will not interfere with any other package system you happen to use, and it is very easy to completely remove, if necessary. 

If for whatever reason you need to remove MacPorts...

to completely uninstall MacPorts

 sudo port -dfp uninstall --follow-dependencies installed

 sudo port -dfp uninstall all

 sudo rm -rf /opt/local  

 sudo rm -rf /Library/Tcl/macports*


Really, its good stuff.
