You can tell whether or not recovery is complete. SSDs know everything, but they use memory chips for data storage. You need to find the cause of the unrecognized.

If a component or circuit breaks down, it can be repaired, but if the memory chip breaks down, it cannot be accessed because data cannot be accessed. The question is, it is difficult to decide whether or not to recover.

Judge the importance of the stored data. If there is important data and indispensable data, you need to recover, but if there is no important data and the purpose is to install a new window and use the computer, check the A/S period of the SSD and get a replacement or purchase another SSD to install Windows.
