$BTC

There is one question that is bothering me. Can you help me find the answer?

1. Can bitcoins lost in hard disk drive storage be found?

The hard disk can suddenly break.

Considering that the maximum supply of bitcoin is only 21 M, it means that in the future the number of bitcoins will not be 21 M, if the number of lost bitcoins cannot be found.

Can bitcoin replace the number of lost bitcoins?

Could this be a weakness of bitcoin? The supply that has been determined cannot be added again
