Go the "A disk read error occurred" error at Windows startup!!!

As usual, I turned on my PC today when I woke up. Went to the kitchen and came back to the PC to find out that the PC hasn't booted into Windows yet. In fact, it was halted at the boot loader saying that it cannot find the boot loader.

I hit the reset button but there was no change. So I went into the BIOS and checked what's up with the boot drives. For some reason, the boot drive was changed to my Toshiba data drive from my usual Samsung SSD drive. I set it back to my SSD and the I got the following screen.

A disk read error occurred

I panicked. This SSD is a new drive and it only has TLC flash. This is the first of its kind so naturally there should be unforeseen issues. I thought this was one of it. The mind runs too fast. I was already thinking about how I'm gonna RMA the drive and how I'm gonna use the PC without the SSD. I thought I would have o install Windows onto the data drive and etc. etc. Then I snapped out of that thought and came back to the real world.

I don't have to think about RMAing anything just yet. There are so many things that I can do before getting there. First I checked if there was a loose connection between the SSD and the motherboard. Didn't appear to be so, but I unplugged and replugged the cable. That allowed me to load the Windows boot screen but even after a minute, Widows didn't fully boot into the desktop. I knew something was up. It should have booted within 10 seconds. I was still scared.

I had a spare SATA cable lying around. So I replaced the old one with this one and guess what happened? Everything was back to normal. Phew! Why do all these cables go kaput?

Because of the problems with the SATA cable, the SSD had not been detected the first time thus BIOS had automatically changed the default boot drive from the SSD to the next drive in the order of the SATA port.
