Toshiba Canvio 1TB- Won't mount on Mac Since updated to Mavericks

Im having the same problem with my External HD. I used it all the time and after I updated Mavericks it wouldnt show up in finder. I can see it in Disk Utility and its grayed out. I tried mounting it and it says that it cant be mounted. I plugged it into my windwos computer and it showed up just fine. So I can rule out the drive or the cord are bad.

Maybe you have a solution for me. I have a Toshiba external drive and it used to work on my old mac book. I have a new mac book and it doesn't read the drive. Doesn't show up even in Disc Utility. I spoke with Apple and we tried everything. They suggested I contact Toshiba. They couldn't help. I don't understand how you fixed the problem. I don't know what exfat is and how you formatted it.

So my drive wasn't mounting but would show up in disk utility. Take the software that you originally installed that came on the HD called "Tuxera NTFS for mac" and throw that on a thumb drive. Then plug in the thumb drive and plug in your external HD and run the tuxera installer. It worked for me now my drive is mounted as it was before I updated to maverick. I don't know if any of yall tried this but it worked fine for me.

TLiT99 - Thanks for the recommendation. My canvio is now showing up after following what you did!

This is the solution here. Latest Tuxera NTFS drivers are located on the external drive. Connect your external drive to a Windows PC and move installer to a thumb drive and install it.

I just created an account so I could say thank you, I was losing my mind trying to fix this, and Apple of course is no help at all, wanting my to change formats for no reason, erase everything 'just to be sure'. Thank you for the solution.

Hello. Having the same problem so I was trying to install Tuxera NTFS but I'm getting an error message:

NTFS-3G could not mount /dev/disk1s1

at /Volumes/TOSHIBA MM because the following problem occurred:

dyld: Library not loaded: /usr/local/lib/libfuse.2.dylib

Referenced from: /usr/local/bin/ntfs-3g

Reason: image not found

Could you please help? I don't have a Window's PC computer. I've always used this Toshiba external hard drive with my Mac OSX and it's been working fine, and still works on my work computer. The problem of not mounting started AFTER I installed Maverick on my home computer.

Thanks for your patience. I'm running out of mine. 😟

google "toshiba portable tuxera ntfs update"

Tuxera offered a FREE upgrade to existing users. The version that came with the Canvio may be outdated. You can download the 2013.2 version from their support page and install it over the old version for a fully-licensed version on Mavericks.

Bravo TLi99! This fixed my problem too!

Thanks a lot TLiT99..! You saved me just when I was about to drown..!!! I painstakingly moved all my files in the Toshiba Hard Drive to another one (211Gb = Hours), in order to format the hard drive in ExFat. I'm so glad that I read through the posts and special thanks to all those who thanked TLiT99. When I saw many "Thanks", I knew this would work. IT WORKED..!!! Thanks again TLiT99. I'm Happy..!!!
