This is why you should always backup the hard drive where you plan to hold crypto coins. I always back up and place the backup to multiple external drives and so on. You should start doing this too once you recover your funds.

Now I am not sure if you can do much about this though. I would buy new SSDs which are the same exact model as yours and try some of the options given on these. Perhaps there is a way to recover if you use parts of new SSD or vice versa, but I am not an expert obviously just following some logic.

I wish you best of luck man. It would be a shame to lose that amount of money.
