I am not running any third party menu bar add-ons at the moment, and I have even disabled spotlight temporarily to see if that is what was causing the accesses to the drive. I also disabled Time Machine because that drive is a Time Machine disk. All my other drives are unaffected. I have an internal, and 3 other externals of varying brand and size. And no iStat installed or other background utility? You could try to start in safe mode.
I did some more trouble shooting. Thanks so much for your help in this. I think you are on the right track. The RAID software needs to keep the different volumes in line.
Keep Drive Spinning

T drives keeps it alive. Turning this off worked for me and still get to use iStat Menu, yey! Thanks for the tip, gotta love iStat Menu! Just tried out your tip, and it seems to work like a charm! Thanks again! Thank you both of you for the solution!!! There is nothing loaded on my 2nd HDD except for Photos that is about 4gbs worth. Please, please, please help me! I going crazy with this. You need to put the entire path to your volume. When I do this command: You need to give the entire path to the volume.
So obviously the disk did shutdown, but it started to spin again after a while maybe 10 minutes.
OS X: Three Common Causes of Slowdowns
If you restart the machine, open Terminal, and do: Maybe the problem is I have two sessions on the laptop, one personnal and one for working. I also use HDD drive for downloads.
But yesterday when I tried all that stuff, this session was not loged. After that, I could use 2 SSD on my mac, and never get any spinning sound…. Having dual SSD disks sounds like a dream. I am having the exact same issue as Juluss, below. Same configuration: I have the power management set to spin down the HDD after 1 minute for either power source, battery or adapter. I just confirmed the pm settings via Terminal, and they have persisted.
I mentioned the wake from sleep timing of this issue, and will add that I have the hibernation sleepimage set to write to the HDD for two reasons: I have been running the command: Recall, the HDD should sleep after 2 minutes of inactivity. Clearly it is not sleeping after 30 minutes. If I restart the Mac, it will promptly spin down. With the SSD, I can quit all applications, restart the Mac and re-launch everything, restoring nearly 60 tabs in Safari all in under 2 minutes which was a minute ordeal when I was only running a rpm HDD , but the 2 minutes is still a pain, and does not address what is clearly an issue here.
The bottom line is that the HDD should spin down, since there is no activity. Any help to troubleshoot this would be greatly appreciated! However, later today the computer will sleep. But it usually fails spinning down after 2 minutes once the computer has awoken from sleep this could be a red herring, for all I know; it could just be hrs or more since last restart , I can go for 20, 30 minutes, easily, without using the HDD, AND most puzzling no HDD activity in Terminal. Which it does after a fresh restart. I had not thought of a firmware issue on the drive. Guess I should research that.
Bummer—I thought I might be narrowing on in this issue when I found your blog, but I could be days into a firmware issue!! Any insight into why Safari is doing this? Thanks a lot for your guide. It almost works perfectly. But something is waking up my drive. So did a small monitoring and this was the result:. Do you have any folders in the dock that resides on that disk? Any applications? I have my download folder on the extra disk now when I think about it.
When I use it to try to solve this problem, the output associated with the unwanted spinup every 5 minutes in my case of the disk inside a Time Capsule looks like this hundreds or more similar lines:. So I wanted to point out to other commenters that the disk name does not necessarily show up at all, it might be a device name — so the grep command would have missed it completely.
What is a spinning color wheel?
That looks like a memory swap. This means that you have too many applications opened, or not enough RAM to handle your task. Best solution? Buy more RAM. Cheap, and OS X loves memory. Hows it going? Was hoping for some help since it seems like you have helped quite a few people out.
Also uninstalled istat server for phone access. Thank you. Thanks for this excellent page. I read somewhere that it might be because of a the optibay caddy mine was a cheap ebay one so I replaced that with a DataDoubler, but the problem persists. I have diabled Spotlight for the drive, and used the terminal command to set the spindown to one minute.

Do you have any suggestion s? I once heard the drive spin down for a few seconds a few weeks ago, but it duly started up again without input from me. Many thanks! If you have the home folder on the WD, the disk will be written to when preferences changes, when you start applications that modify files in your Library folder. The best solution is to have OS X and your user folder installed on your SSD disk, and link larger folders to the hard drive.
I have iTunes music on my hard drive, so naturally the disk will spin up when listening to music. Same thing for the Movies folder. Every time you save a document to your home folder, the disk will spin up. You see the problem? Following your grep instructions, I notice that every ten seconds I have an entry like this;.
Do you have any background management applications like Hazel? Try to quit all utilities and apps. Thanks again -would starting up in Safe Mode achieve this most effectively? And, would you happen to know what the launchproxyl entry is about? I did the above and found that Java and Firefox are accessing? Do you know what I could do? Where do you have your download folder? Sounds weird that Java accesses the extra drive.
Are you sure your not running anything else written in Java? Java could be my Crashplan. But I have it set to backup every hour. So I reckon I could have been unlucky.
