R2D2WD.WD HDD or external hard drive displays not initialized, unknown in Windows 10, 8.I will provide a response for each step listed in the article. I have not tried another USB cable, because 1) it is a special cable that is needed to connect this My Passport device, and 2) it worked just fine with my old iMac.I went through all of the steps that were possible in the article/link you provided. And as stated above, it connected properly to my old iMac. I just recently tried to connect it to my new late 2020 iMac, and it will not connect, just like many others who I’ve read that are having the same connectivity issues since using macOS Big Sur.There is no physical damage to the My Passport device. Please note that I have connected the 3TB device into the same USB port on this iMac as the one I have currently plugged the My Passport into, and the USB port functions correctly with the 3TB device.The My Passport drive was accessible and functioning properly approximately 2 months ago on my old 2009 iMac running OS X El Capitan. You can that a different Western Digital device is connected correctly, it is a 3TB device that is formatted as 2 volumes, one for regular use, and one used specifically for Time Machine Backups.

Shortly thereafter first one, then all three of the backup APFS containers have disappeared without being deleted. Disk Utility previously successfully created three APFS containers that were used to create backup images on this drive. MacOS is Big Sur all current (11.3). My WDeasystore 4TB was recognized on my 2019 MacBook Pro 16-inch using a USB-C to USB 3 adapter. 6) Since it showed up correctly on my old iMac, the device has not failed.I have a similar problem. I am not contacting Apple about this issue, this is a Western Digital My Passport issue. ![]() ![]() As soon as the drive is unplugged, the spinning beachball ceases and all other applications, clicks, and keystrokes start working again.I’m writing in response to this posting rather than others reporting invisible drives with versions of OS X or macOS because of the similarity to description including the spinning beachball cursor.Just jointed the community today. Even opt-cmd-ESC does not work to access the Force Quit menu. It is impossible to correctly eject the drive for two reasons: it is not seen, and the computer is unresponsive. Let disk cleaner have access to files macI didn’t own the 12 TB My Book before last Friday, so can’t speak about it prior to my current setup, but the Passports have worked fine since Big Sur 11.0.1, and even Catalina and Mojave, etc. I have a late 2015 27" iMac, and running Big Sur 11.4, and all drives function fine. Since then, they just work. My Passport 4 TB drives (a few years old now)I’ve used the firmware update tool on the My Passports, and was sure to have the latest firmware at the time. Just specify your drive model and follow the upgrade instructions. You can find the firmware update tool under WD support. You can legally virtualize macOS from version Lion to Big Sur without needing the Server version. There are a couple suggestions I can give you:If you know how to work with Virtual Machines, you can use VMware Fusion 12 for free (for personal use.). From what I’ve read, your drive works, but NOT on Big Sur. For droves that don’t show up at ALL, I would usually question if the drive controller was bad, or not, or even if there was platter damage. So hopefully I can give feedback that applies to both sides.Well, based on the problem I’ve read about on this thread, the Hardware should at least show up in Disk Utility, even if the volume doesn’t mount on the desktop. However, that machine is rarely used anymore, and the iMac is my main computer for now.Hope this helps someone, I know coming to a place like this everyone is on a different experience level and some just don’t want really deep technical solutions. Just reading this thread suggests people here may not have a lot of technical experience with dealing with drives, so I don’t want to go overboard here with suggesting things that could make things worse, if you don’t know what you’re doing. For a VM you can connect the drive directly to the VM via the USB and bluetooth settings so it will function natively in that guest OS.You could also try safe mode on the Mac, boot while holding shift.If this was a desktop drive (not the passport drive) I would suggest taking the drive out of the enclosure from WD, and either put it in a drive dock, or buy another enclosure from some place like amazon, Newegg, etc. You could also use Linux if you know how, just to simply confirm the drive still works.What you would want to do is chose whichever guest OS, or alternative Host OS, you want to work with, make sure the drive mounts on that platform and install the necessary WD tools. Mac usb serial terminal emulatorI’ve exhausted every suggestion available on via apple. Are you on the Apple Communities at all? I’ve been working on there to get some help, and so far, I’m still stuck…trying to reinstall El Capitan on that machine. It was that old, and my Time Capsule would no longer power up, which is why I removed the hard drive, and I just figured it wasn’t worth it to me, with newer technology and faster connections available, etc.But, you sound like an awesome resource for another issue I am having with my old iMac (27" Late 2009 model). But my old version is no longer supported on Big Sur, so I never even thought about that.But, I like the idea of looking into VMware!I recently (in fact, just this past week) disassembled my old Time Capsule (from 2009) and took out the 1TB WD drive! I was going to put it an enclosure, but then just decided not to.
