Likely clearing SMART won't help.
There is another more severe firmware problem related to media cache.

[fulmine500]

do you have any suggestions?

As mentioned before, suspecting it is a media cache issue.
Learn and work on how to deal with that would be a suggestion.
Start by reading critical system files.
Do you have firmware tools like PC3000, MRT or DFL?

It is odd you are getting different error msgs every time, this makes me wonder...
could you list them all (or most of them at least)?
