Makes sure that a connected drive never goes to sleep.

Overview

Keep Drive Spinning ensures that a connected drive never goes into low-power mode. Normally this can be controlled using the Energy Saver preference pane in System Preferences, and that should be your first resort in dealing with the problem, rather than this or any other third party software. However, some external drives do not respect the System Preferences settings, so for them an alternative like this is needed.

This applet simply creates a launch agent that tells OS X to update a hidden file on the selected drive once every minute so that the drive stays awake. Launch agents are built-in OS X technology and persist across reboots, etc., so you can run this once to set-it-and-forget-it. You can find the launch agents made by Keep Drive Spinning in the LaunchAgents folder of your user's Library folder.

Users on OS X 10.4 (Tiger) and OS X 10.5 (Leopard) need to run the AppleScript source code directly. This source code is included, and only requires opening the file and then clicking the big, friendly Run button.

It seems that MacUpdate has started serving up bogus, adware laden "installer" files instead of the real software unless you are logged in with a MacUpdate account. I think this is horrible. To bypass this, please download Keep Drive Spinning directly from http://jon.stovell.info/software.

Two questions: 1. If I uncheck "Put hard disks to sleep when possible" in Energy Saver, will that leave my drives spinning even when the computer is sleeping? 2. If so, then will Keep Drive Spinning also do that? I would rather drives slept while the computer is asleep.

If your computer falls asleep, the drive will be free to go to sleep, too.

WOW! Finally I can immediately see any directory on my external 6TB drive as soon as I click on it! I aliased my Documents, Movies, Music and Photos directories off of my 1 TB SSD and onto a huge, fast drive once they outgrew the boot volume. Before this utility I had to wait at dozens of times a day for the drive to spin up and the disk index to be read. THANK YOU Jon Stovel!

Can't get this to work on 10.12.4 Sierra. I have a 4-bay USB enclosure that I swap out Hard drives on periodically - does it recognise drives under this type of configuration? I have set each drive, and have had the same 3 in for about 2 months now - they remain unaffected & still need to spin up.

Keep Drive Spinning is completely agnostic about how your drives are connected to your computer. As long as your drives show up in the Finder and you can write data to them, Keep Drive Spinning can work with them.

If you are still in need of troubleshooting help, please post on the Keep Drive Spinning support forum at https://groups.google.com/forum/#!forum/keep-drive-spinning

I am using this application to keep my Airport awake (which has another external USB drive connected to it storing my iTunes library). This appears to work great while my Mac is powered on and even when I open/close iTunes, but when I reboot the MacI have to go into iTunes preferences to reset my iTunes library location to the External/Airport drive. Is there something I can do so that I don't have to set this every time I power on my machine or no?

Your problem falls outside the scope of Keep Drive Spinning. However, I have had similar experiences with iTunes in the past, so here is some completely UNOFFICIAL advice:

Instead of storing the entire iTunes library folder on your external drive, try storing just the iTunes Media folder on the external while keeping the rest of the iTunes library folder on your local drive.

I've been running this program for two days and it is fantastic. For 18 long months, I've wanted to throw my $6000 Mac Pro out the window for these constant drive load-up delays in Final Cut, After Effects, Photoshop and Finder. Keep Spinning is simple, free, and harmless as far as I can tell. I leave it in my dock and make selected drives "live" before beginning an intensive work session, and then deselect the drives when I'm done, allowing them to go into their normal energy-saver mode. While a plummeting Apple stock and lack of innovation continue to frustrate customers, thank goodness someone is creating solutions like this. Would recommend A+

Works beautifully! I've had a Mediasonic 4-bay ProBox running for a number of years with Keep Drive Spinning. I found this program after going through all the Mediasonic forums and endless web searches trying to fix my drive issues. Thanks. On a real positive note, I see the developer "actively" answering users in this forum. I say actively because it's not unusual for software dev to be slow and half-assed (mind you, a lot of users don't put in the effort or have the knowledge required). The fact that this is free software and nicely supported is kinda rare.

Thanks, Winstonsmith. It's nice to hear that the software has been helpful to you. There's also a Google Group for Keep Drive Spinning at https://groups.google.com/forum/#!forum/keep-drive-spinning, which is a better place to post question, bug reports, etc., than here.

I had such high hopes for this but my external drive still disconnected. Very frustrating. It appeared to be working but that was perhaps due to the fact that I was accessing the drive constantly updating my family tree...... Wish it had worked.

If your drive is falling asleep even though Keep Drive Spinning is working, or your drive disconnects itself from Finder, or it loses data, or anything like that, you probably have a hardware problem. Back up your data RIGHT NOW! You may need to repair or replace the drive.

To be clear, Keep Drive Spinning keeps healthy drives from going into power saving mode. It does not fix malfunctioning drives.

It was a brand new drive a year ago & has always disconnected itself. Gives me error saying "it wa improperly ejected". Same thing happened with the other older drive I had, which is why I bought this new one. Husband suggested I get another drive but who's to say it won't do the same thing. And yes I have been backing it up to the other hard drive. Frustrating...

Hi smolson999. I'n afraid those are symptoms of hardware issues. It might not be the drives, though. It might be a bad cable, or even a bad port in your computer. I'm afraid Keep Drive Spinning won't be able to help you with any of that.
