    Does anyone have the WD My Passport Essential SE 1TB working on Lion? I just received mine, and it will slowly transfer data (~2Megabytes/s) for timemachine and after a few hundred megabytes the drive is no longer mounted and I have to unplug it from USB and replug it for the disk to be recognized.

    Any thoughts?

    Ahh, I've not done my research and have the same problem.
    Has anyone tried the firmware update as suggested by clingfreeze? Does it work?

    I do not have the Passport version, but the My Book Essentials. I used Disk Utilities to reformat the device, splitting the disk into two. One partition is for the iMac/TM and the other is a FAT partition for Windows.

    This is the 2TB USB2 version I bought more than a year ago and re0purposed for the new/first Mac in the home. I have also tested successfully the newer 3TB USB3 without problems.

    I did have to remove the factory-loaded partitions using the Western Digital utilities via a Vista laptop, though.
