Without any noises or fanfare, my 8TB My Book stopped being recognized by my PC. At first the HDD didn't show up at all, but after a few reboots it did. In Disk Management it showed as not initialized and unallocated, with no partitions.

I think this is a corrupted MBR or whatever they use for 8TB drives. This is a non-boot drive just for storing files. It's still in it's housing and has always been a USB attached drive with 1 large partition.

I still don't know why the drive is now showing unallocated in disk management when all I did was a typical reboot. /shrug

What's the best way to go about diagnosing/confirming & fixing this? I'm hoping that file recovery won't be needed if the drive's MBR got partially corrupted.

Update your post to include full system hardware specs and OS information.

Include PSU: make, model, wattage, age, condition (original to build, new, refurbished, used)?

Other disk drive(s): make, model, capacity, how full?

= = = =

Unfortunately anything you do could cause data loss or further data loss.

Start by posting a screenshot of the Disk Management screen. Expand the screen so all can be seen and then post the full image here via imgur (www.imgur.com).

Is that WD 8TB My Book using only host USB power or does the My Book have its' own independent power supply? The images I found appear to show just host USB power.....

More information needed.

WD's webpage "In the Box" section indicates there is an AC adapter so perhaps that failed. There's also a second cord visible in their video. But if it failed at a critical point in writing to the disk professional data recovery service may be needed. OP could try reading the adapter's labelling to check the voltage and wattage provided by it and might be able to substitute a replacement adapter but will most likely still need to send the whole thing out to a service company.

I did try several USB cords in different USB ports, but not a different power adapter. I do have a 2nd 8TB, so I could see if that works, but that won't help in critical file info for the partition is partly corrupted.

I'm wary of even rebooting this thing since the drive wasn't even seen for several reboots.

Ignore this post. I just forgot to "reply" to people so I'm not sure if they'll notice my post.

Can you retrieve the SMART attributes?

Can you show us the Partitions tab in DMDE?

I'm actually surprised it took this long for someone to say something. lol

On top of collecting old anime that never made it over to the west, I'm also a photographer. RAW files take up a lot of space, as do 4K videos.

You can kind of see my progression as tech changed and my needs changed regarding the portable drives. 2TB, 3TB, 6TB, 6TB, 8TB, 8TB. lol

Anyone have any other suggestions, or know which side is 'face up' for WD My Books?

Thanks!

That's insane amount of external drives.
Do you need to use them all simultaneously?
 
I think, you're hitting some USB power limits because of number of external drives used.
And that is causing drive disconnect and partition table corruption.

If you insist on using external drives, then connect only those you're currently working with.
Disconnect idle unused drives.
External drives are not meant to be constantly connected. Connect, use, then disconnect.

If you want to use drives as permanently connected, then install them internally (unless your pc is a laptop).
With 3x 20TB internal drives you could replace all your 9 external drives.

What makes you say that? The error in my last screenshot?

Does anyone know which way the HDD's face in the enclosures? I might try laying it on it's side, correct side up.

SMART data are stored on the platters in a reserved "System Area" (SA). Therefore, an inability to retrieve the SMART attributes would suggest that the heads can't access the SA.

DMDE can't read sector 0. I expect that it will have the same problem with all other sectors, in which case this once again suggests that there is a head/media/firmware problem. (Most of the firmware resides in the SA.)

That use case screams out for a NAS, rather than a bunch of USB drives.
