So I'm using an external USB 3.0 enclosure Age Star with 3GB Hitachi disk inside it as my Time Machine storage and as a general storage for music/video files. It was working just fine till this morning. Now, when I connect it, it does not show up in MacOS. The enclosure has two indicators, for when the disk is powered and when it's in use. When I hook it up to any of the macs I own, the "in use" indicator starts blinking (it does not blink when I hook it up to a windows laptop). Also the sound that the disk is making corresponds to the sound it was making when it was in use. When I try to launch Disk Utility, it get's stuck on "loading disks" spinner forever. If I disconnect the drive, then launch Disk Utility and connect it back, it does not show up there. I did the PRAM reset with the disk connected, it did not help. I hooked it up to a windows laptop, it did not show up either. I think there's a very high probability it was not disconnected "properly", probably simply powered off (maybe while in use). What issues could this cause? If it's the drive that is causing issues, what are the chances to restore the information that's on it?
