Windows 10: SSD drive not mapped after Windows 10 Creator update

Finally bit the bullet against my better judgement and updated to Creator last night. Low and behold, my internal Samsung Evo 850 SSD is now not mounting. I checked the BIOS as well as ran Samsung Magician utility and the drive is there. It also shows up in Disk Management but it won't let me assign a drive letter. This is a working drive, not a new one, with much data on there I don't want to lose so I'm sketchy about running these other disk partition tools.

Anyone know what I can do?

Thanks!

Update: One of my external USB 3.0 drive is not recognized either, yet another USB 2.0 is recognized fine.

Windows 10 Creators Update crashes SSD boot disk

Hi,

I have Win10 installed on an UEFI boot
Samsung EVO 840 SSD and installed the Win10 Creators Update and when I returned to the PC after leaving it to complete the update it was at the logon screen and unresponsive. I reset the PC after making sure there appeared to be no activity
(HDD light, etc.) and it came up with a "please insert boot disk" error. I then went into BIOS and the SSD was not in the detected drive list. So I opened the PC and disconnected/reconnected the SSD and rebooted successfully. After logging into windows the
system froze after about 5-10 minutes. So again I rebooted and got the "insert boot disk error". I repeated this a few times after swapping SATA & power cables and motherboard ports for the connected drives and still got the freezing issues after 5-10 minutes
followed by the SSD disappearing in the BIOS.

I was quite confused and annoyed that somehow just after the update my SSD had crashed (as this was the only thing that had changed). I have now uninstalled the creators update and the PC has now been running for several hours with no issues. Has anyone
else experienced this problem with an SSD boot drive setup and is there another solution to the problem so that I can continue to receive updates? I would also be interested to learn how an OS update can cause the BIOS to fail to detect the drive until I open
the PC case and fiddle with the SATA cables?

Cheers.

 

Update: Running mini tool's partition wizard I was able to re-mount the SSD successfully. However, when the system is rebooted it is unmounted again.

 

Once you mount the SSD with Mini-Tool change the drive letter to lower in the Alphabet, either in Mini-Tool or Disk Management (ie) T: or S: or whatever.
