SSD not initialized and unable to initialize

Did you try Disk Management?

I have 3 disks on my desktop : 1 M.2 disk (boot disk) , 1 SSD drive and 1 HDD drive . Everything was working well until yesterday i was unable to access some files on the SSD drive . After restarting the computer the SSD drive doesn't appeared anymore . 

In disk management appears as "Disk 1 - Unknown - Not initialized" . When i click to initialize i got the error "A device which does not exist was specified." . What can be the cause of this ? How can i initialize the drive ?

There could be several reasons due to which ‘Disk Unknown Not Initialized’ error message may occur, which are mentioned as following:   Corrupt/ Incompatible/Outdated Driver, MBR Corruption, Missing or lost partition, Bad Sectors in hard drive, Corrupt File System etc. To solve this problem we apply some fundamental manual steps like: update the device driver, Rebuild the MBR boot, initialized disk, assign a drive letter, Run CHKDSK command and Run diskpart utility.

To initialized the disk go to Disk management > and locate the drive that not initialized > the drive will show unallocated. > select unallocated disk > Right click on it > click initialized disk > select between GPT > Click OK.

Once the process is done, you will redirected to main windows and check you can access it or not.

Hi and thanks for reaching out! I'm an Independent Advisor and a Microsoft user like you. Please allow me to assist with your issue.

There is a number of possibilities. If both of these does not help you, it is highly probable the drive is faulty.

1. Try to remove and install the SSD again, hopefully it's just a matter of re-seating the drive.
2. Remove the drive and use an external enclosure (USB) to access it.

Also look into Event Viewer as described in this wiki. If you are able to find something like it, then it is definitely a hardware issue.
