I have an external HDD connected to my MBP (2016 model). Everytime the machine goes to sleep I get the "Disk Not Ejected Properly" message, which I find annoying. There doesn't seem to be a real problem. The drive is reconnected and accessible so it seems to be just annoying.  The questions are:   Is this really just something annoying, or is there an actual problem with this? How can I make the notifications go away?   The HDD is a "LaCie Porsche Design Mobile Drive - 1 TB"  I have seen this question:  but it is rather old, blames the behavior on a special brand of hdd and also is about the drive not being usable, so I think my question is different.

Been running El Capitan since it was officially released. Updated to 10.11.4 a few days ago. I have a WD Elements USB 3.0 drive connected to my Mac mini (directly to the rear ports, not via a hub). Ever since the update to 10.11.4 whenever my Mac goes to sleep and I wake it up again, I get a notification to say the "Disk was not ejected properly".  This has never happened with this drive before, not on Mountain Lion, Mavericks, Yosemite or El Capitan until now.  I have another external caddy also with a full size 3.5" drive in it. This is powered by the mains.  It seems to me that the Mac is now terminating power to the USB 3.0 port prematurely (before the disk has had a chance to unmount properly ?), I do not get the message for my full-size disk that is permanently powered.  Tried adding the disk to the spotlight ignore list but to no avail.  Anyone else notices this issue?

I don't know whether this is my laptop SSD hard drive issue or it is Windows 10 issue. A quick  of mine is here, showing an .   Though now, Oct 2015, I still have the problem every time I open File Explorer right after a reboot.  E.g. Opening drive D: will take me 20 seconds to have the file list loaded; the content displayed as "Working on it" when we wait. I expect it to be immediately available when opened; the same as previous Windows 7.  Do you have the same problem? How can we get around that?

I received a new HDD from my uncle, RAW file system. Tried CHKDSK, but it didn't work because of the RAW file system.      Update  I ran SpinRite 6 overnight and it got nowhere. Stayed at 0% for the whole 10 hours. SpinRite also gave me a notification that this drive is most probably toast. I think I am going to throw this drive away.

I'm having a problem with windows constantly spinning up my secondary HDD. My main OS is on the C: partition of my SSD and on my HDD I have a D: partition for storage and an E: partition for recovery. Indexing is disabled for E: and D: and currently paused for all locations.  Setting the Windows power settings to turn off my HDD after 1 min of inactivity makes the drive spin down, but then wake up after around 20 s. When I set it to turn off after 2 min of inactivity it spins down very rarely, suggesting that there is something that is accessing the HDD at irregular intervals between 1:20 ~ 2:00 min. I have identified a peak in the resource manager that corresponds to the HDD activity.   This peak is high if the HDD did have time to spin down and then was woken up by the process causing the peak. The peak is tiny (but still there) if the HDD never had time to go to idle. Under the bar "Disk Activity", there is no image that has "D:" or "E:" in its path, so all I can do is to watch the peaks in the graphics to the right, not identify the cause in the list.   Using Sysinternals Process Monitor, I filter for any process that includes "D:" or "E:" in its path, and this made me able to identify and disable the QueryFullSizeInformationVolume via the registry key NoLowDiskSpaceChecks. However, this process did not correspond perfectly to my HDD wakes and disabling it did not help. As of now, Process Monitor reports that zero processes are accessing my HDD.  After reading another thread, I also tried disabling my page file (even though it's located on C:), just to see if this would make any difference, but it did not. I also tried to disable the controller for the HDD in the Device Manager, but this just made my drive remain spinning constantly. When I installed Win 7 a few months ago, my drive stayed quiet until I clicked it in Explorer, so I there is something that has changed within the last few months either with Windows or with some third party software. However, the same behavior is present when starting Windows with all non-Microsoft services disabled, suggesting that third party software probably isn't the culprit.  As of now I'm pretty lost and searching the web isn't helping me. I might try to boot another OS from a USB, but If anyone has any advice that can point me to a solution of my problem I would be very grateful.

I have 13 inch mid 2010 macbook pro. Just installed new 1T hard drive but now am hesitating on what to do next. I have my old hard drive converted to external drive and a back up drive as well.

I have this external (USB) drive that can't seem to be disconnected correctly.  Whenever I eject the drive, it won't disappear from Disk Utility.  Afterwards when the drive gets re-connected again, it cannot be mounted. At this stage, I would need to reboot the Mac to get the drive to mount again.    Ejecting from the Terminal via diskutil eject /dev/disk2 returns a Disk /dev/disk2 ejected message and unmounts the disk.  However the disk still shows up both in Disk Utility and diskutil list.   Furthermore even after the USB cable is disconnected, the disk still shows in both Disk Utility lists — GUI and command line.   How can I solve this?  OS: macOS Mojave 10.14.1 (18B75)

I have 4 hard disk drives that have temperatures which go beyond the recommended 50 degrees (Celsius). (I have several Samsung Spinpoint F3 which are 1Tb each and they do have good temps, between 32 and 35 degrees. That's normal for me. But in this case, 50+ is not normal.)  I have already read the question and answer provided , but none of the solutions  helped. What tools can I use or what terminal commands should I execute to lower the temperature of these drives?  And on a similar note, if I were to use a method similar to , how would I know which hard drive I am reading?   Where can I check to see which HDD is related to, for example, /sys/class/scsi_host/host0/link_power_management_policy ?  I have already tested powertop, hddtemp, disks and others to check and try to lower the temp with no luck.

I have a MacBook Pro (10.7.3) and an iPhone 4 (5.1). When I'm trying to conserve outlets, I charge my iPhone at night by plugging it directly into my computer.  If my computer is asleep with the lid closed, when I plug in the iPhone, the computer briefly wakes up, and it takes a few moments before it starts charging. (If the computer is already awake, the charging is instantaneous.) But my computer takes a while to go back to sleep because it saves the contents of RAM ().  How can I plug the iPhone it in to charge, without waking up the computer? (And why does this happen in the first place?)  (I've already set up my computer so that iTunes and iPhoto don't launch when I plug in my phone — but this doesn't seem to be enough.)

When you unplug an USB drive without unmounting, your OS warns you about how dreadful could be such operation for your devices (I'm on OSX).  I usually follow the advice, unmounting before unplugging, but it happened many times (thousands) that, at the end of my tasks, I just unplugged (Hd storage, Cell phones, etc..) and I never ever noticed corrupted data on my devices. Am I lucky or can this annoying warning just be ignored?

MacBook Pro (15-inch, 2016) with 2 USB-C to HDMI adapters. The setup works great if I start up in that configuration.   If I connect the adapters while the machine is running or simply sleeping, one of the monitors will never get a signal and stay in low power mode. The OS sees the monitor, it shows in the display arrangement settings and I can move the mouse into it, but until I restart, I can't see anything on it.  Once I have restarted I can let the machine sleep or whatever, and the display still works unless I disconnect the adapter. As soon as I do that a restart is required to use it again.   Using MacOS Sierra (10.12.4)  Using this adapter:

When I plug in a removable 1TB USB disk in my laptop, the operations led keeps blinking for a while and then you can hear the servo mechanism resetting with a short "tack".  I'd like to recover the data.    I believe there might be some way to get the data through low level IOs.    What I believe is that the mounting process assumes the disk is OK and I should prevent this before using ddrescue or something similar.  Does anybody have a solution to this problem?

I had a Mid-2012 MacBook Pro that recently stopped booting. I narrowed this down based on troubleshooting of the boot device to likely the SATA/hard drive connector/cable no longer working for whatever reason.  I have decided to sell the system. I'd like to know if I remove the hard drive (or in this case, an after-market SSD I've installed) from the system, will there be any other data (i.e. iCloud data) stored on the system on any other chip that I can reset in any way? I plan to reset the SMC/NVRAM before I sell the system off of to someone else.  Additionally, if I remove the hard drive, is the system still associated to iCloud (specifically Find My Mac) or any other service? If so, how do I disassociate it? The system will no longer boot even if I put in my boot device.  Thanks!

Okay here is my situation, I have a 1tb internal hard drive that is plugged in via USB Dock, and has external power, that I use for weekly backups, but my question is, is it better to leave this hard drive on all the time, or turn it it off manually when it is not being used? What is the best case scenario?

I made the biggest mistake of my adult life and installed Yosemite without backing up my HDD. Fortunately, I do have most of my actual files and programs saved to my external HDD, but that leads to another problem.  I use a lot of 3rd party apps to make music, and they are not compatible with 10.10 i.e. Pro Tools etc. I formatted my HDD in an attempt to start over but it keeps reinstalling Yosemite from the Internet.  I've made several USB boot drives but when they go to load up it just gives me "international no" sign (see image below).  Can someone please help me as my work/life is tied in to my studio. Oh also my external HDD is now all of a sudden read-only NTFS instead of Mac read/write enabled.

I am sure many of you guys know the flashing folder icon which shows up when the Mac cannot find a drive to boot from. My 2017 MacBook Pro has this issue for some time now, but recently I found something interesting.   The MBP won't find the boot drive, as long as the battery level is at > 70%.   The Mac boots just fine at lower battery levels; no issues whatsoever. Now, the problem is, I don't want to run my MacBook via battery the whole time or keep on disconnecting the AC power when 70% is reached every time.   Does anybody have similar symptoms and did find a better solution? Do you think there is a hardware issue with my device?   I've been to the Apple store before (when I didn't knew this was connected to the battery level) and they couldn't find anything. They suggested I reinstall macOS, which of cause didn't change anything.  Edit: One detail I forgot to mention was that when I charge my MBP and close the lid, it crashes and gets really hot (fans turn on slowly). I'm not totally sure on this, but I think this also happens with lower battery levels.  Battery Info:

(Updated answer choice for High Sierra. See the old answer if you are still on Yosemite)  I'm running OS X Yosemite, and I want to disable the notifications from Time Machine. I rarely do a hard-drive backup because all of my essential files are in the cloud. I don't need to run timemachine as often as it suggests/warns/annoys me about.  How do I disable the notifications? Time Machine is not in the Notifications preferences, and I don't want to stop using it entirely.

I tried everything on this page:  except Open Firmware (Intel macs doesn't support this).  Then I tried using the terminal but this didn't work either.  Every time I bootup my mac the drive tries to eject it but it can't. I ran the Apple Hardware Test (hold d on startup) and it sayed that all is fine. (it also tested the slot in drive).  And I put my mac upside down and booted it up (hoped that the cd could come out) but it didn't work. (same problem)  How can I get that out of my slot in drive? Mayby with a tweezer?  Any ideas?  PS: in finder there's no visible cd and in the diskutility there's nothing too
