IIRC SD cards and most SSDs don't go through error check routine when powered, it has to be specified. Some do use the power-on time and run a routine if left on for too long.

You usually you have to read the entire drive to maintain, in my case S.M.A.R.T. reported changes to reserve blocks after doing that on an old drive.

I have a 16 year old 4GB SDcard with all data still intact.

Some amount of the data is almost certainly recoverable, but getting it done commercially is going to be $$$.

10 years in use. On a phone.
