Crucial MX300 525GB SSD Disappeared from UEFI

I purchased a Crucial MX300 525GB NAND SATA M.2 Internal SSD about 6 months ago. I installed it into my laptop (ASUS VivoBook F510UA) and it was working great up until a couple of days ago. I opened the laptop and windows booted to the HDD that came standard with the laptop, instead of the SSD. I navigated my way to the UEFI/BIOS and noticed that the Crucial SSD had completely disappeared from the computer. I then went in and checked the Device Manager, and it was not showing up there either. 


After reading through some older posts here, I was able to complete a power cycle on the SSD, which resulted in the SSD showing back up in my UEFI/BIOS. I then booted Windows from the SSD, and everything worked normally for about 10-15 minutes before I received the BOSD, along with the error "Critical Process Died." When I rebooted the laptop, the SSD had completely disappeared again. Stubbornly, I tried another round of the power cycle, only to get the exact same result. 


Admittedly, I'm only tech savvy enough to have figured out why I wanted an SSD and how to install the SSD, and I've probably reached my max in terms of ability to solve the current issue that I'm having. Any guidance/advice would be greatly appreciated! Thank you.

Re: Crucial MX300 525GB SSD Disappeared from UEFI

I am sorry to hear about the issues that you are experiencing with your Crucial SSD.  The error that you received during the BSOD seems to indicate that there is an issue with the image on the SSD.  This can be caused by a number of things like Windows updates not installing properly, or old outdated drivers causing system instability.  This issue should not make the SSD disappear entirely from the system like you are seeing though.  This would lead me to believe that we have a bigger issue going on here. 


If you can still get the SSD to show up after performing the power cycle procedure, then we will want to attempt to run repairs quickly on the SSD before it goes back into the BSOD.  I will leave you a link below that will walk you through attempting to fix any missing or corrupted system files on the Crucial SSD.  If the SSD does not allow us to perform the fixes, you can simply attempt to format the SSD in Windows and wipe everything off of it.  We can then attempt to clone again from your original HDD and see if the issue is resolved.


Fix Missing Corrupt System Files: 


If the above troubleshooting does not correct the issue, we will need to look into setting up a replacement on the drive for you.  The MX300 series of SSD will come with a 3-year warranty from the date of purchase and we would be more than happy to get you taken care of with a replacement.  You can contact us directly using the information that I have provided below if troubleshooting does not fix the problem.
