Passport and Maverick

I have just updated my mac to maverick and now neither of my passports will show up in finder. I do see them when I go to disk utility. I’ve installed the drivers and firmware. Please help! Thanks!


Were you using the drive only on Mac?

Are you able to test the drive on a different computer?

Do you have any WD applications installed on the Mac?

When you goes to the disk utility are you able to run first aid on the drives?

I am able to use it on both Mac and PC. I tested it on another computer and it works fine, I have two and they both are working. I installed the drivers and firmware from the WD site. I can see the drives in utility but will running first aid erase any of my data? Thanks!
