MX300 1TB died after about a month

I bought a 1TB MX300 (S/N: 1652152BC31D) from Amazon on February 11th, to upgrade a laptop from a 500GB SSD from another manufacturer.  I cloned the original disk to the MX300 using Macrium Reflect and all was well for about a month.

On March 6th the drive Died.  Laptop wouldn't boot.

I put the original 500GB drive back in and my system came up.

When I try and hook up the drive to the USB adaptor I used to clone to it and attach it to the system it shows up as a drive but no capacity is listed.  If I try and launch Disk Management it never connects to the disk management service.

How should I proceed?

Hello Joe,

Thanks for your message.

In most cases, your SSD can be returned to normal operating condition by completing a power cycle. This resets the firmware in the SSD to allow it to be detected again. No data is lost during this process and it will take approximately one hour to complete.

Simply follow the steps from this Knowledge Base article:

On occasion it is also possible to reset the controller inside the SSD by performing a firmware update. The firmware update tool may detect the SSD even if the power cycle has not worked successfully. You can find details on the update process by selecting your SSD model from the list on the following link:

For instructions on updating the firmware, please follow the steps for Method 2 on the guide below:

Am trying but have my doubts.


The referenced doc suggests "A sudden power loss is a common cause for a system to fail to recognize an SSD".  My system is a laptop with an internal battery.  When it died it was also plugged in.


Even if the power on the plug had failed the battery would have protected it from 'a sudden power loss'.

No joy.  Still a bricked drive.


If I try and run Storage Executive with the Drive attached it just goes into space when you try and refresh the system to detect the drive.
