that a sector on the disk is no longer writable. As long as it stays with one sector it is not too bad... but after that I got the message:
Self-Test Log error count increased from 0 to 1.
This has me just a little unsettled. In addition, I wanted to know if there is a possibility that this "known" error is no longer reported every 30 minutes? So that only again an error message comes when more errors are added?
