Question Need help restoring the partition on my WD 8TB My Book.

[Darkmatterx]

Without any noises or fan fair, my 8TB 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 partition.

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

I still don't know why the drive is now showing up 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.

Win 10 64bit Pro

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.

Can you show us the Partitions tab in DMDE?

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.

OK, so here's some of the info requested.

PSU Corsair RMx850x

Problem drive is a WD My Book portable drive. Uses both USB and power adapter for power, which is plugged into an APC UPS.

All components new and individually sourced by me. Approx. 3y.o. Maybe 4.

I haven't tried DMDE before, but I can take a look.

Thanks

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.

DMDE showed me this after I took a peak inside the "advanced" options, although I touched nothing inside it.

The error itself is kind of expected, but without knowing the error code itself I stopped there and quit the program.

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

8 TB MyBook being the I: drive - correct?

Actually I need to remove those letters. They're from my old system. The drive in question is disk 6, which is just below the 8TB that shows as working. The bad drive has no letter and chkdsk says it can't scan it because it's "raw."

It appears that the drive has physical problems, probably heads or media.

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.

That's insane amount of external drives.
Do you need to use them all simultaneously?

 

[Darkmatterx]

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!
