My OS is on a 512gb M.2 drive, but the main storage on my laptop was a 1TB HDD, it started making noise about 2 weeks ago so I backed everything up onto a 1TB SanDisk USB SSD. This afternoon it got very clicky when I booted it up after work and icons for a few games I had stored on it, like KSP and YUZU, disappeared from the desktop and taskbar.
When you click on shortcuts and the path was not found and suddenly common windows DLL are simply missing. RIP.
