Recently I was doing a Windows 10 upgrade on a machine when a user turned the machine off (at the plug).
They were running a Sandisk 500GB SSD and when rebooted the machine said that there was no boot device.
I expected that the MBR just hadn't been written since Windows was halfway through installation, so tried to re-install but now whatever I do I can't get this SSD to show up anywhere I try it.
I have a SATA caddy which I've used for many other SSDs/disks and never had it fail to talk to one so I tried plugging into that - the caddy has a blue light which comes on when you plug it in and then blinks a few times as it reads the disk.
With the Sandisk SSD the blue light comes on for about 30 seconds then just disappears. The BIOS on the host machine recognises the disk as a Sandisk SSD, I just can't seem to get Windows to understand that the disk is a disk.
It doesn't show up in diskpart, disk manager etc.
Scratching my head here - could the SSD have been damaged somehow when it was writing and the power was lost?
I've tried other disk management tools such as MiniTool etc but I don't think the SSD is even being recognised as a viable disk by anything that I plug it into so I'm not sure where to go from here...
