I use a Macbook Pro and a couple of days ago, as I was moving some picture files onto my drive, it suddenly said that I had somehow ejected it the wrong way. The thing is, I hadn’t ejected it at all.

Most of the time, when you connect an external hard drive to your Mac’s USB port, you soon see it mount on the desktop. Apple likes to ensure these are easy to find, so they also appear in the Finder in the left-hand column under Devices How to fix an external disk drive that won't show up on a Mac. Read this article till the end to fix My Passport not opening on Mac or unable to copy or transfer date between them. Some users have recently reported that their My passport for Mac not showing up on Mac which is a very serious issue.

The following day, the same thing happened as I tried to move the same files again. It might be worth mentioning that I was moving a lot of picture files, and they were heavy picture files. Now, whenever I connect my passport to my Macbook, the WD Smartware icon appears, but My Passport icon does not. I can’t access my hard drive, or any files on it. Sometimes my hard drive will be accesible, but then it ejects itself as soon as I click on it, saying that I didn’t eject it properly.

Is the problem to do with the USB connector? Or the actual hard drive? What should I do? Edit: Now, not even the WD Smartware icon will appear. It won’t show up as being connected to my Macbook at all, and when it does connect it just ejects itself over and over. Same thing is happening to me!

I am on an imac, running 10.6.7. I started receiving the same alert msg. That the disk was not ejected properly, though I had not ejected it.

Then the WD software icon started appearing & disappearing, then my drive icon did the same, and now I my mac does not see it at all. I tried to update the WD firmware, but it won’t work because it does not see the drive. Mine is connected via Firewire 800, not usb. I’ve tried the usual, unplugging, rebooting, etc., but to no avail. Yes, I saw your suggestions before I posted. My mac does not have “First Aid” but I ran my Disk Utilities before I posted and all is well with my mac.

I don’t have another mac to plug it into to & don’t want to use on a pc, which is why I bought the mac version. Also, my understanding is if the problem was power-based, the FW connection would not be an issue, but a usb might. Mine is connected via fw 800.

Are you suggesting the fw cable that was shipped with this drive may have all of a sudden went bad? Would this really cause what appears to be a drive software issue? This doesn’t make sense. Usually when a cable goes bad, it just doesn’t work. I don’t think the erractic behavior of the wd software icon appearing & disappearing would happen if a cable went bad?

Does a usb to ethernet adapter work for a machine. Best way to test it is trying it with a different computer or different cable.

Disk Utility should show first aid on Mac OS X 10.4 and above. If you want to get to first aid for the drive just select the drive that your going to test on Disk Utility and you’ll see the option. Further info on what to do can be found on this.

That way, you'll never lose more than 5 minutes of work. Make sure the Save AutoRecover information every x minutes check-box is selected (highlighted in red within Figure 3, below) - x denotes the number of minutes. Also, choose how often you want to save the AutoReceover information, to do so, enter the number in the Minutes box. Try to enter a small number in the minutes box, like 5.

Hi Guys Sorry to be stealing the post, just hoping like minds can help me Have a WD My Passport 1TB and all was working fine. Use it mainly for movies, was copying a file to it and it froze. I unplugged it without 'removing it safely' (yes I know this is probably where the trouble it) and now I can't find anything. Plugged it into our DVD player to watch movies and it didn't show up as anything connected. Plugged it back into my Comp and nothing came up (normally AutoPlay detects it immediately).

Have run Dskchk a number of times, sometimes it would say its in use and asked if i wanted to run it as startup (which I did do). For a short time it popped up in My Computer but was very very slow at accessing it (realise its probs corrupted). But now I have nothing. It is flashing like its in use (again still not showing anywhere). Can see it in Device Manager and Disabled and Enabled it after the message (device cannot be started) and now it reads that 'the device is working properly', which of course it's not.

Have tried deleting it from device manager and reinstalling it. The driver wizard thing says the installation cannot be completed (cannot find the right stuff to install), as it searches for 'unknown' instead of 'My Passport' etc. Have gone onto WDs website and downloaded the drivers from there and done the above step but browsed to that file instead of a random search. The HDD is not showing up in Computer Management. Oh it also makes a little clicking noise every now and then (awesome I know). Thinking it's a lost cause, but hoping someone on here can help me fix it. Any advice would be great.
