2Days ago the drive of the macmini has disconnected. After the restart has came back. Today the same event. I opened it up and i saw that the second connector of the logic board has been disconnected. I get it back to its position. I use the second HDD, as a storage. Now when i play music in itunes i have some crashes/stops without reason (especially when I change track). the same thing happens at the moment with the transmission. DiskUtility says everything is fine. I tried to stop transmission, and move out some of the folders to the HDD, and the itunes crashed again. Is the Drive destroyed because it was unplugged during power failure? Is there any tool I can check the HDD? Disk Utility says everything is fine. Maybe Connector went off?
