OP wrote: 'I will certainly do so once I get the data off- I have 10 issues of my magazine on it and I'm under deadline' Your first priority is to PROTECT THE DATA. I suggest you take the drive to ANOTHER MAC (not the one giving you problems). Can you get the drive mounted? Can you see the data? Then, the next step is to attach ANOTHER DRIVE and 'copy over' the data. Once the data 'is safe', now it's time to 'go to work' on the drive. I suggest you follow the advice in reply #5 above: - GET RID of the proprietary WD software - ERASE the drive using Disk Utility (Mac OS extended with journaling enabled) - TEST the drive using DU's 'repair disk' button.

What report do you get? - IF you get 'a good report' from DU after doing the above, REPEAT THE TEST FIVE TIMES in succession. Do you get a good report each and every time? - IF SO, I'd continue using the drive.
Everything was fine until the upgrade to 10.11.6. Now on my desktop, my connected external Time Machine drive no longer shows the Time Machine icon (like it used to), it's just the plain yellow drive icon. And when I plug in another external drive, it no longer automatically shows on the desktop (like it used to), so I have to go use a Finder window to access it (vs. Previously just clicking the icon for a finder window). Yes, I've done all the Preferences options, and everything listed here short of a total reinstall.
This is why I got away from Windows.). My WD 2TB HDD suddenly ejected automatically and a message of improper eject came up. I connected the hdd again but it did not detect. It was not showing in disk utility either. I checked it in another macbook but same issue. Then I connected in windows laptop and it got detected in USB 2.0 port but was not showing up in windows explorer. I checked in disk management and tried to open it but was not opening.
Right clicking was giving me only two options: delete volume and help. All other options were greyed out. Can anyone please help here?
I don't want to format the hdd. Is your drive password protected like mine? My computer was being glitchy and when I tried to eject my g-drive it wanted a password, something I never saw before 'wanting a password to eject.' Once I entered the password, the drive no longer appeared except for in Disc Utility. After days of panicking and trying to 'verify disk,' I right clicked on the disc and it said 'unlock.' I entered the password and it worked! The drive still doesn't show up when plugged in until I go through disc utility to unlock it, but at least I have access to it again.
