Seagate 1TB won't mount after mavericks upgrade
Last night I upgraded my White early 2009 macbook from snow leopard to mavericks 10.9.2 and now i cannot mount my Seagate 1Tb external usb hard drive, It appears in disk utility and the drive is there but the partition on the second line is faded and it will not mount. When i try to mount the drive i simply get an error telling to run first aid but first aid simply tells me that i need to format the drive. as this is my main drive with all my back ups on it i do not have another drive that can hold all of my data. also when i booted the macbook into the recovery module after holding option at startup the drive appeared healthy and fine under disk utility there but under the full os i cant open it in Finder. Its not the drive as i can use it perfectly fine on my other laptop and pc. I need this resolved asap please 🙂
MacBook, OS X Mavericks (10.9.2)
