I regret the day I upgraded to Windows 10.  It seems that I have lost years of important data including all my 4 years of school, important documents, photos, music, everything.

 

Upon restarting after the auto-update, my Local Disk D was just gone from My PC.  It shows up in Disk Management, but it's showing "Unallocated Space" and 698.64 GB of roughly 700 GB free when I had like 300 GB used.

 

I don't know what to do, I'm at a loss.  I have no effing idea why a Windows 10 update would erase someone's secondary hard drive...

First of all, restore from your latest backup.

 

I doubt that Windows 10 caused this problem itself, it might have just happened to fail at the same time.

 

If the HDD is still registering it might be that the MBR is corrupt. Have you installed Classic Shell or Audacity at the start of August?

 

Have you tried the obvious of just restarting the machine again or power cycling completely just to make sure it's not a glitch, I would always recommend doing this first before trying anything else.

It wouldn't; Windows 10 updates don't erase secondary hard drives.  I would restart the PC and then see if the issue is repaired.  It may just be that the HDD or some sectors on it were corrupted and are not reporting correctly.  See whether if you roll back to your previous installation the problem is solved.  Let us know what you find out.

Nope, Microsoft never makes mistakes... or has bugs in their software... or lies to their consumers... or....

At this point you need to evaluate your data situation.   If you have a recent backup (which it sounds like you don't) have that ready to restore the data.  

 

If you don't have that on hand, find a good data recovery utility to check the hard drive to see if the file allocation table is still intact, just windows isn't seeing it.   If it is intact, you should be able to use a partition recovery tool like this:  http://www.partition-recovery.com/   to restore the data.   Here is a free partition recovery tool from a reputable company also: http://www.easeus.com/partition-recovery/

wtf, I typed up a huge post to help and the forums ate it .... anyways use this >> http://www.easeus.com/partition-recovery/

 

I unhid it, seems there was a glitch.

Anyway back on topic, you definitely want a partition restore software if you can't restore it via Windows or rebooting. Good luck!

Ok, so I don't know if this is good or bad, but Partition Recovery sees all my data on the drive, and Windows sees the drive as "Unallocated Space" and that there is nothing on the drive.  What options do I need to run in this program and does the Demo version have limitations?

Hello,

 

This is a known issue with Windows 10 Anniversary Update.  See this thread here on Neowin, this one in the Microsoft Answers community, or this thread on Reddit.   You have a couple of options right now:

 

  1. Roll back to v1511, and the missing disk volume will re-appear.
  2. Try running the aforementioned EaseUE Partition Master, AOMEI Partition Assistant, MiniTool Partition Wizard or another free tool and see if it can recreate the partition table data in whatever format the Windows 10 Anniversary Update now expects.

If you don't have any backups, or the data on the missing drive is particularly valuable, I would suggest going with option #1.  I would only suggest option #2 only if you can afford to loose the data on the missing disk volume, just in case the third-party tool doesn't work.

 

Regards,

 

Aryeh Goretsky

I'm not too familiar with rollbacks.  I mean, I know what rollbacks are, but how is this done in Windows 10?  Is there certain options for it?  I'd rather be able to save all my data than risk losing it.  And also, how do I prevent these idiotic autoupdates in the future?

 

Thanks in advance!

Hit up the action bar next to the clock > Settings and Update and Recovery, then find the Recovery option > Go back to an earlier build
