I've searched and searched this topic, it seems to be common, but with slight different circumstances and never a reliable solution.
A month or so after installing Mavericks on my Retina MacBook Pro my Seagate FA GoFlex external 2TB USB 3.0 stopped mounting. It worked fine for 7-8 months on the previous OS.
Disk Utility still sees it, but the partition is greyed out and won't mount. Repair Disk shows the drive is OK. Drive is Mac OS Extended format too, not NTFS.
I installed Seagate's Dashboard software in hopes it might fix a compatibility issue, despite the fear of their software corrupting drives, no luck.
Recently switched to a new Mac Pro, still doesn't mount.
Works with Windows:
If I use Bootcamp and restart into Windows 8.1, the drive mounts and I can read the files perfectly fine. Very odd I'm having more luck with a Mac formatted drive on a Windows OS.
Solution???
Haven't found one. Is there a Mac compatibility issue, did something go corrupt that doesn't effect Windows, only Mac, plus, will it happen again even if fixed? And finally, a solution that doesn't involve a $99 repair program.
I've restored the data from TimeMachine to another drive, but it's older, slower, smaller. I plan to reformat the Seagate after making an extra back up directly from the drive in Windows 8.1. Then hopefully after reformatting on Mac it will mount and stay mounted.
