Question: Q: WD My Passport for Mac won't mount on my Mac Pro My 1TB external hard drive is less than six months old and was working fine; now won't mount on my Mac. I don't remember disconnecting it without ejecting it but I do think I got a message about needing to eject before disconnecting.

Thank you Paul-nz, but no, it doesn't show up under Disk Utility. I had a similar problem several months ago with a WD My Book that I was using as my Time Machine backup. It took it several hours to appear on my desktop, but finally did and I was able to copy off my files onto this new WD My Passport, then run Disk Utility on the My Book and now it is working just fine. I bought the My Passport to copy my files from the My Book. So all my work for several years is on this My Passport. Now I can't get the My Passport to mount even when I leave it connected to my computer overnight. I don't know how to access the files on this My Passport so I can back them up and reformat the drive.

Historically, the problem has been that many USB-powered drives can't get enough power from a USB port after they begin to age. The Passport is bus-powered, getting all its power from a USB port.

Not the best solution for a desktop computer. To get such a drive going again, you need one of two workabouts: 1) a powered USB hub (has its own power supply to make up the shortfall) that goes between the external drive and the computer.

2) use a 'Y' USB cable to get power from two USB ports simultaneously (such as ) Also, WD uses an odd proprietary formatting scheme that is of itself a problem area. WD makes very good bare drives but the enclosures into which they put them to make an external drive are not very good and not particually Mac-Friendly.

The formatting makes them harder to use. Once you get the files you need off the external, consider erasing and reformating it to Mac Extended Journaled using Disk Utility.

That often makes the drive more reliable without having to revert to USB hubs or special cables. It gets rid of the proprietary formatting that seem to contribute to the problems. I have three external drives. All have WD bare drives inside but none are in WD encosures.

By far the best enclosures for Mac external drives are those from OWC: I have two of the desktop model shown and one of its portable version for my MacBook Pro. All three have given me superb service and zero problems. Jan 6, 2015 12:23 PM HI, I have a some what similar problem.

I am afraid the drive is in big trouble. In the middle of copying files, I accidentally unplugged it.

Now it WILL NOT MOUNT! It shows up in disk utility and passes verification and repair with flying colors. BUT it won't mount. ( I tried both the disk and its indented partition) the partition remains grayed out and I get an error when I click on the mount button. What's worse it wont mount on my other macbook pro or even my sony vaio.

On the sony it does not show up but under disk management it 'volume appears to be OK' and I dont get a chance to repair it. So am I screwed? I need the data but balk at 1000 dollar softwares that 'may' fix it. Any suggestion? I took a look at the upgrade (I have Data Rescue 3). When you go to check out in the purchase process, you find a Data Rescue 4 flash drive ('Bootwell') added to your 'basket' for an additional $15. Any thoughts on the benefit of having the flash drive, as opposed to just running Data Rescue from another hard drive?
