I have a Samsung 860 EVO mSATA 250GB SSD that is my OS drive. Samsung Magician says it need a firmware update, but it won’t take a firmware update. Everything goes through the motions, but when I power on, I’m still on the older firmware.
I got in tough with Samsung tech support, and we went through all their different procedures one at a time to no avail. I finally got an email saying that I would have to return the mSATA SSD to them to have the firmware updated.
I created a full drive image using Terabyte’s Image for Windows, pulled an identical Samsung mSATA from my Windows 7 Pro Dell Latitude D800 (which I haven’t been using), opened my desktop and swapped out the two, then powered up and booted into my TBWinRE USB thumb drive. I restored the full drive image to the substitute mSATA (which included all partitions and partitioning info), then did a restart and removed the USB thumb drive in the process.
Just like old times. I’ve packaged and UPS’d my stubborn drive to Samsung in New Jersey, and was told 5 to 7 business days for a turn around. Time will tell.
