**Background:<br />**
I plugged in my seagate back up hard drive today (not time machine) after a few months and my computer can read the drive but not write to it.  

**Two obvious problems:<br />**
1) The drive is formatted as NTFS<br />
2) The drive has (from top to bottom) "Read & Write", "Read-only", "Read-Only" permissions.<br />

I know what you are going to say, but the NTFS writing software that seagate has to write to these type of drives doesn't work on this version of mac I guess because the update killed it.  When I try to run the software mac says "the developer needs to update this software to work with this version of mac".  I know each of those two problems are the cause of this issue but I am unable to find a solution.  The "Ignore Ownership on the Volume" checkbox in the drive's show info box is not there.  Does seagate have new software for this (I use a lot of open-source stuff, but for this I would prefer seagate official software)
