As my Time Machine I’ve had a perfectly performing 320GB G-drive mini, USB-connected, for several years. It’s still got a good chunk of space on it. BUT in recent weeks I have been getting desktop messages saying that I failed to shut it down properly–when I haven’t shut it down at all. My iMac is on 24/7, and backups usually occur regularly, even when the g-drive has supposedly been shut down improperly. Sometimes the icon disappears from the desktop; sometimes it doesn’t, despite the messages (which stay on the screen till I close them). To get it to appear if it has actually disappeared, ie, get the mini to function again, I need to use the on-off switch, and it then works again. (I don’t know whether that is a proper shut-down.)
This may be related to interruptions in power or Wi-Fi connection. Does anyone know how sensitive my gadget is to micro-interruptions of some sort? Do I really need to replace my mini? I’ve run Disk First Aid on it, by the way–no real change in these odd shutdowns.
Thanks!
