Do I really need to replace my SSD?

About three months ago my 11" macbook air fell from the table and landed on it's front left corner (if it's before you as if you want to open it). There was some minor observable damage (a small dent). But the laptop worked just fine for about 3 months. And yesterday I tried to turn it on and got the "Mac OS utilities" screen. Disk utility tells about the "invalid B-tree node size" and I can't do anything about it (fsck, fsck_hfs etc. do not help). Also I can't turn it on in the safe mode. So I gave my laptop to one of the repair companies. They tell me that I need to replace SSD and that all info is 100% lost. But the SSD in macbook air is on the opposite side from the one that it fell on. And it worked fine for 3 months or even more. So, is it possible that what they tell me is true, or do they just want my money?

P.S. And also, I live in the country where there are no official Apple service centers or something like that.

There are defective SSDs on the market, they will fail after some time. SSDs usually do not get damaged by shock. Contact apple and they will replace your SSD for free. Since this is an official replacement program, apple may cover shipping costs. Ask them

Will they accept it with visible signs of external damage?


They will unless they believe the malfunction is caused by physical abuse. In this case it can go either way, depending on how they see it. It seems to be software/SSD firmware error to me. There is no mechanical parts that can be damaged by mechanical shock in a SSD. These suckers are used in aircraft FDRs, if they can survive an airplane crash, it's highly unlikely a drop can damage your SSD. "invalid binary tree size" is a file system error, there are some software ways to fix this. Try them. If everything fails, go find apple for help
