| 3 CarlaMac, on May 21, 2008 9:57:55 pm BSTI had the same problem with the Western Digital My Book Essential 1TB External Drive that I bought. It kept failing when I tried to reformat it for my Mac as Mac Extended (journaled). I was ready to return the drive because it was so frustrating!
I called WD customer support and they walked me through it over the phone:
This is what worked perfectly:
Use the Apple Disk utility software that comes with your Mac.
PARTITION your Mac as 1 Partition and while you are in that same window, SELECT OPTIONS.
THIS IS THE KEY: There are 3 radio buttons in the popup window for formatting options. The drive was preset as the bottom button PC formatting and you have to chose the middle button which is for Mac.
Click apply and finish formatting your drive. Works perfectly.
One other thing, it is a good idea not to have any applications running when you format the drive.
Hope this helps. | 5 emurphy, on May 26, 2008 5:35:09 pm BSTI want to say THANK YOU for posting how to format a WD 1TB drive for a Mac. I've spent an hour going crazy. And your steps worked perfectly. :) |

I would like to join the othes and thank you for those instructions. I too just got a My Book and was frustrated as I was unable to format it using disk utility. The options setting was what I was missing.
Regards

| 27 Silvertooth, on Jul 17, 2008 3:17:02 pm BSTHey - you're a life saver (not like the candy)
Thanks for these steps! I was struggling with it myself too.
Appreciate you sharing!
Just a note - when I called Mac support, they told me to choose the top (GUID)
I don't know what kind of difference it makes, but I never would have found it without you!
Cheers! |
| 29 Fretbuzz, on Jul 23, 2008 7:57:55 pm BSTI have to thank you! I was just about to return this drive when I came across your post. THANKS! |

| 50 waveshredder, on Nov 24, 2008 4:29:12 am GMTTo Carlamac,
thank you, thank you thank you,
As all have said before, thank you. After reading all rel: FAQ on WD site pointing at disk utility, again and again, and emailing WD, who pointed me back to disk utility, full stop. no other instruction? I took mine back to Magnum Mac here in NZ. They also didn't know after both of us re google-ing found your answer, I know we are in a download everything world, and should get lastest updates, but an install disk included with the drive AND INSTRUCTIONS could help, after all these HD aren't cheap.
Clearly a few people have had an issue with this. Forwarded to WD email help desk also.
Thanks again. |

| 68 jimmybivona, on Jan 7, 2009 9:28:18 am GMTThis was your post. I have a comment:
I got similar help but for Time Machine: some of my folders were case sensitive so the format had to be Mac OS Extended (Case-sensitive, journaled). Of course it didn't tell me that. I had to stumble on the solution after I did a total format. My MBP chose this on its own even tho I had selected plain journaled. And the drive must be virgin. And TM will still erase the drive before it begins. Picky, ain't it.

| 95 BILL, on Mar 25, 2009 5:08:19 pm GMTThanks, your suggestion worked perfectly. I actually took the WD drive I bought back to best buy thinking it was defective as I have reformatted WD drives in the past for Mac and it had worked fine. But with these 640 GB drives I wasn't getting anywhere. I googled for some ideas and your advice has helped me to properly format my 2nd WD hard drive for Mac OS. Thanks again. |
| 96 Steve, on Mar 26, 2009 12:26:38 pm GMTIt worked!
Thank You, Thank You, Thank You, I thought I was going to loose my mind. |
| 98 xttom, on Apr 3, 2009 8:36:07 am BSTThanx carla... u really saved my ass... :) Was goin nuts over this issue.. well, i selected the GUID partition option. I guess the difference is that u con also install Mac OS X, so that the system can boot form this drive with a GUID partition. |
| 99 Gator, on Apr 10, 2009 2:22:18 am BSTThe steps to resolve this are not working for me. The drive works fine on my new imac with 10.5 OS, but on my 10.4.11 when I try these steps to reformat (because its not recognized) I get an input/output error when I press partition.
Any ideas? | 113 Smylight, on Jul 8, 2009 5:56:21 pm BSTHello,
I have the same problem as you. Did someone steer you towards a solution?
Thanks! |
| 116 sunflower, on Jul 20, 2009 10:32:59 pm BSTDear Gator,
I had the same problem as you with my MyBook external hard drive. I was able to format it and put data on using my Mac running OS 10.5, but got an input/output error when i tried to partitiona and mount it on my other computer runing 10.4.11. Did you ever find a solution? |

| 126 bugalug, on Sep 7, 2009 5:26:21 pm BSTI have just purchased a WD Elements hard disk and have just dragged some files into it. Not sure I've done this correctly though - I have tried some of your suggestions, but keep getting an error msg:
Partition failed with the error:
Could not unmount disk
Is this a problem with the actual hard drive? I've also tried to erase the disk and get the same error msg. |
| 127 teach, on Sep 18, 2009 5:21:13 pm BSTHi
It was a while ago but you answered a question on installing a WD hard drive on a mac. I too got the error input/output and tried following your advice but even if I pick the middle radio button I still get the same error - any more ideas? |
