Hello This is a strange one I am facing. My now antique Sunflower iMac was showing some slow response times. I did a little check and discovered that the disk was about to fail, backup and repair ! So I did a backup and re-run disk utility, now everything is ok. I tried other options such as unix, onyx, and these all indicate SMART as "verified" Anyone have any suggestions on what can make this happen? Is my disk dead or not ?
