hmm is there a way to flag bad sectors? Or to check the condition (like SMART)?

I have to repair the sqlite message database once a month btw. Otherwise SMS I write do not appear.

sqlite3 /home/user/.rtcom-eventlogger/el-v1.db VACUUM;

Not sure how old. I bought it a year ago and it looked almost mint (no wear on the keys).

True with the fat32.
