Large external storage stops working after being connected for a long time
.everyoneloves__top-leaderboard:empty,.everyoneloves__mid-leaderboard:empty,.everyoneloves__bot-mid-leaderboard:empty{ margin-bottom:0;
}
I have a 4 TB LaCie RUGGED USB-C external hard drive, and when it's connected to my MacBook Pro (13-inch mid 2014) for a long time without being used, it stops working. I do allow drives to sleep when connected in the settings.
- Icon remain on desktop, but trying to open it or ejecting it, causes Finder to hang.
- When I unplug it, Finder unblocks
- When I plug it in again, it’s working (for a while of course)
- The drive is bus powered and does not have an external power source
I use this drive for Time Machine backups, but sometimes Time Machine fails to backup.
I’d like to isolate the issue to know if the Mac is the problem, the cable is the problem or the drive is the problem or I need to change settings.
Can I use a system log or Time Machine log to diagnose what’s happening?

Hi. I’m going to edit this. Please put a potential answer in as an answer. “Trying energy saver” is an answer - not an edit to the core question. Also - just edit things so it’s correct - the system shows who edited and when in the edit history. apple.stackexchange.com/posts/356779/revisions

I’ve also edited out at least 4 side questions. One question per question is best. How to troubleshoot is great. All the potential avenues can be stand alone answers and help many people that have a disk not responding.

@bmike - will do, I didn't have a fully coherent A'er so didn't want to just give the OP a link w/o more details and evidence.

I searched around and found out that there's an option in Energy Saver: Put hard disks to sleep when possible and it's checked on my Mac. You can see the option in the screen shot below:

Very good changes. I would potentially disable PowerNap as well while you chase down sleep/wake/disk arbitration issues. The battery shouldn’t affect things, but one thing a battery does do is act as a capacitor and even out bursts of energy demand that the charger won’t/can’t provide. If your Mac is powering this drive over USB - that might be a root cause of not enough energy to spin up - even if you are connected to a charger - the Mac still has to supply power to spin up a HDD in some cases.
