I had the Dude set up on Hex with a microSD card. After a few months A problem occcured: database malformed. It turned out the SD card failed, so I replaced it and it was fine for a while. After some time it happened again. After four microSD cards and two pendrives had ben destroyed by Dude, I decided to move it to a PC with standard HDD but it didn't solve the problem with the database malformation, it still happpens very often, sometimes four, five times a day and it's extremely irritating. I've checkd the database with SQLite and it didn't find any problems. Is there any solution?

I had the database broken few times too even the sd card is still absolutely fine. There were no other option than importing the backup. Even mikrotik was not able to find anything and the ticket stayed unresolved. Don't forget your sd card is much more bigger than the database and keep it almost free to ensure the wear leveling process can take care of the cells.
