Is an SSD drive alive?

Question

linux

Hello. Now I use a 320 GB HDD from Samsung as the main hard drive. There is also a 60 GB SSD from Silicon Power, the system used to be on it, but at one fine moment the ability to write and create files disappeared, the SSD was no longer detected. After 2 months, he reappeared. Can it be used?

Answer 1

Of course not. The inability to write to disk means complete degradation of memory cells.
