Laptop: Acer Travelmate P645-MG, Windows 10
According to Notebookcheck, the SSD model in their review unit was a 256GB Toshiba THNSNS256GMCP mSATA SSD. ( https://www.notebookcheck.net/Review-Ac ... 645.0.html
The trouble started when I repeatedly attempted to install the Creator update, but it kept freezing at 32% installation after reboot. I first attempted to do this on May 12th.
I used a system image to restore the OS to a condition a few months ago, ran CHKDSK /R, sfc /scannow, and the DISM restore health commands. Nothing seemed unusual. When I ran the Creator update again, this time it aborted the installation before the reboot step.
When I opened up Event Viewer, it's full of "The device, \Device\Harddisk1\DR1, has a bad block." errors, and they started appearing on May 16th, after my initial multiple attempts at trying to install the Creator update.
SSD-Z reported "n/a" for literally every single information, including device name, serial number and most importantly, the SMART info. Some of Windows functionality won't load at all, and Windows Defender and Malwarebyes are very sluggish.
Currently I'm creating another system image on the backup HDD (1 image from January, another from early March), but I'm confused of how the SSD could be failing. I highly doubt that I burnt through the over-provisioning of the blocks.
EDIT: I ran Command Prompt to check the SMART status, and it says that the SSD is "OK". Huh...
