I recently bought a WD "My Passport" drive - 500GB USB2/3 including WD's own Smartware software. I had to replace it. This is what happened.

 

  1. I reformatted the VOLUME not the drive, in Disk Utility, from MS DOS FAT32 to Mac OS X Extended (Journalled)
  2. I created 3 partitions
  3. I used two partitions to copy the contents of the 2 partitions of my ancient Wiebetech FW drive
  4. I named the third partition Time Machine
  5. I spent a whole day creating an encrypted disk image the size of my PB G4's HD in the TM partition

 

Though very slow, it seemed to do everything. The next day it took forever to recognise the partitions, and the drive kept making a metallic tapping sound. Of the first two partitions, it would show either or both, but trying to switch between them in a Finder window caused Finder to freeze and the computer needed a hard reboot. It didn't show the TM partition, except in Disk Utility.

 

In the end, I phoned Amazon to say the drive was defective and they sent an identical replacement. This time I :

 

  1. Deleted the WD software first
  2. Reformatted the drive to Mac OS X Extended (Journalled)
  3. Copied my Wiebetech HD to FOLDERS not partitions
  4. Set up Time Machine to use the remaining space (plenty of room left)

 

So far, it seems to have behaved itself. HOWEVER, when I go into Disk Utility, the top level still shows the drive to be MS DOS FAT32. Yet the VOLUME (which is the same size as the whole drive) is Mac OS X Extended (Journalled). Does this mean the replacement drive is also faulty?

    1. b.Select the Erase tab, then confirm.  This will erase the entire disk.  (If you want, you can select Security Options, then Zero-Out Data to physically erase the entire disk by writing over everything.  This will take quite a while, and usually isn’t necessary, especially on a new disk.) 

     

      This may not work if the drive is already set up with a non-Apple Partition Map Scheme, such as is used on Windows.  If that happens, just continue with item c.

    Normally, you should be seeing the Partition Map Scheme (APM or GUID) for the top level of the device and the formatting (Mac OS Extended Journaled in this case) for the indented volume(s).

    My guess is you didn't erase the drive first before partitioning and formatting.

    Since you are using this drive for TM, you might want to have a look at these two other pondini articles
