Forum Question: Is Lion compatible with My Book for Mac?

Can/should I upgrade to Lion from Leopard if I am using WD’s My Book for Mac? (WD says it has no timetable for a Lion version.)

    The hard drive file systems haven’t changed. A hard drive is still just a hard drive. Not sure why they say anything about a “Lion version” — maybe they are just referring to some free software that comes with the drive? As a drive, it should work just as it always has.

    Received this from WD about upgrading to Lion with My Book for Mac on board:

      Are you using any special software that came with the drive?

    Just their SmartWare.

      Not sure what SmartWare is. I searched for it and it is mentioned on the WD site, but I can’t figure out what it does for you. Do you use it? What for? It is probably SmartWare that is what they are saying in not Lion compatible.
      I don’t think I’ve ever used that type of software that comes with a drive. I just reformat it and start using it.

    I upgraded to lion yesterday. The mybook still works as a hard drive but the time machine function doesn’t.

      Can you clarify? You are using the MyBook as a TM backup, and now TM isn’t working. Is there an error message? What is going on?

        Yup, same here – installed Lion today. Just backed up an hour before installation and now TM won’t backup (‘can’t access drive’ it says). But iMac still recognises the drive itself.

    I have WD My Book for Mac connected via USB to MacBook Pro and use Time Machine for backups. After installing OS X Lion, the My Book is no longer recognized as connected to the Mac via USB. It does not show up under Devices in Finder, and Time Machine says “Next Backup: When disk is connected” in TM Preferences. Help?

      Have you tried to contact WD for support? I guess there is something non-standard about that particular drive that prevents it from working on Lion. Can’t image what or why. Call them and see what they say. Let us know.

    Have a new Imac with Loin 10.7
    My Book has been deleted of all so it is empty to run with the new machine.
    When connecting my book to the mac all works if not shut down.
    When shut down and when mac is turned back on desk top appers normal ny book is in the right place, the mouse arrow moves around BUT can not operate any items and cannot shut down.
    Pull out the lead from ny book to the mac, and all works well. Spoked to mac and they could not help.
