Hi, my 2011MBP stop working all of a sudden after not using it for about 1 week. It was previously running on OS High Sierra. When I switched my mbp on, it only shows white screen. My OS was installed in my SSD. And the only way to keep my MBP running is that I had to switch to my HD and install a new OS on it and only it operates.

From there I got into disk utility and tried to repair my SSD but does not work. It was showing my SSD but first aid does not work. I took out the SSD from my MBP and tried to read it using another MBP and still the same. First aid does not work as well. Reformat is my very last resort as I still have important data in my SSD and wish to recover them.

Anyone knows what's the possible cause or any reliable restore service within KL area?

Thanks.
