SFL Posted May 12, 2020 Share Posted May 12, 2020 My daily set up is as follows. I am experiencing something which never happened before. iMac (late 2012), 16GB Memory, 2.9 GHZ Intel Core i5, NVIDIA GeForce, 1TB (free space 870GB): this computer only holds apps, such as Lightroom, Photoshop, Apple's own apps, etc) My working drive: 5 year old G-TECH G-DRIVE 2TB Portal Hard Drive USB (all my created docs and 2015~ today images are stored here including Lightroom catalogue) (free space 567GB) Seagate 1TB external hard drive USB for Time Machine backup. I copy my G-Tech drive by using SuperDuper on 2 separate external drives at the end of each day. This morning when I woke up my iMac, I was greeted by the following screenshot. All the above mentioned external hard drive remained attached to iMac overnight. Also the G-Tech drive was making grinding noise for about 20 mins before it settled down. It never happened before. What do you think may cause this problem? Is it likely, my iMac or external drives, that became problematic? Is it likely hardware or software problem? Your advice/experience will be very much appreciated. Sung PS Link to comment Share on other sites More sharing options...
