Hardware :: External HD Randomly Ejecting?
Apr 4, 2010
I have a 1 TB WD external hard drive I store my music and videos on. I have noticed that the hard drive will randomly eject itself causing me to have to turn the external hard drive off and back on for the iMac to mount it again. I have a new iMac i5 and had a 24" 2.4 GHz iMac previously. I was using the firewire port on my previous iMac before and would occasionally experience this problem. However, having to use the USB port on the new iMac it is occurring on a daily basis. I have tried different ports on the back of the iMac thinking it was a USB problem, but that didn't seem to help. I have run disk utility and it says the drive is in good health.

I've seen several discussions on external drives randomly ejecting, but didn't see any concise resolution. I have a Western Digital Passport, P/N WD320ME-01 2209A, using the OEM USB (2.0 I think) cable (~12 inches long). My ~4 year old mac book is running OSX 10.7.3. I use this drive for Time Machine B/U. Seemed to work ok (no ejects) when Leopard was the OS, but, after going to Snow Leopard, and now Lion, I get 'disk improperly ejected' errors when trying to run TM, or ever Repair under Disk Utilities. I did get one good TM back up, under Lion, after reformating the drive [extended (journaled)], but the next time I tried to run TM I started getting the 'improperly ejected' errors. Don't know if there is an issue with Lion (and earlier SL), or with WD drives. The fact that it originally worked leads

I have an external laCie Usb drive, that as the header implies, is ejecting itself randomly.
I use the first partition for general storage, the second is for TM backups.
It has never failed to finish a backup, nor has any large (5gb or larger) file transfer to the storage partition ever errored out. It appears to be completely random.

i have a Beyond Micro mobile disk USB external hard drive connected to my imac running Leopard. Once in a while during it randomly ejects by itself and i get the "Unsafe Removal" warning pop up. I don't do anything to the drive at all. Is it a software thing? or is it about to bail?

All software uptodate. I have strange issue with USB ports. After ejecting USB drive (external HDD, powered by USB bus), which worked perfectly, USB port does not recognize anything, nor providing power. Turning MBP off and then booting back solves this issue.

MacBook Pro, Mac OS X (10.7.3), MBP 15" 2011

This is proving a bit a bit of a puzzle to me. I have a 1TB External LaCie hard drive connected directly to my iMac via USB. It has two partitions, both empty. I set the back-up going and it works for a while and then I get:"Time Machine could not complete the backup. The backup disk may have been ejected or disconnected from your computer."
I've amended the Energy Saver settings in the system preferences to keep the machine on given the length of time the first update is going to take, but this doesn't seem to make any difference - and I'm not even touching it! I promise! Then the drive disappears from the disk utility. I then have to turn it off and then on again to get it back. I have the TM widget and this is what it has to say:
Starting standard backup
Backing up to: /Volumes/Time Machine backup 70/Backups.backupdb
Ownership is disabled on the backup destination volume. Enabling.
Backup content size: 196.7 GB excluded items size: 1.7 GB for volume Macintosh HD
233.92 GB required (including padding), 465.34 GB available

I have a Seagate 500gb GoFlex external drive, which I'm using with Time Machine to backup my MacBook Pro. Now, when ever I eject the drive (by right clicking or dragging to trash) it appears to disconnect from my MacBook, but the drive itself continues running, i.e., the lights stay on and I can still here the fans / drive whirring away. This continues unless I pull the USB cable out. Is this normal? Should the drive completely shutdown upon ejecting? Or is simply 'ejecting' from the MacBook enough for 'safe' removal?

Mac OS X (10.7)

I own a few external harddrives, however one in particular (western digital 2tb) will randomly disconnect and a window will show about "device removal with the red little stop sign shape" then it will randomly connect again (and sometimes i have to physically unplug it and plug it back in), does anyone know what is going on here? None of the cables are being touched, it's really strange, the only thing i can think of, is maybe i have a loose usb cable and need to replace it? or maybe a faulty usb port?

So I have an external hard drive hooked up to my MBP via USB. I've noticed that every now and then (maybe every half hour or hour?) the drive spins up. It's actually really annoying, as the drive makes a loud sound as it spins up.
I can't figure out why it does this; the drive spins up and then goes back idle. Time machine is DISABLED, spotlight index on the drive is DISABLED as well. I use the drive solely for storing movies/music. There are NO applications installed on it. The only apps I have open are finder/preview/safari/firefox/adium/itunes. My guess is that some process is trying to access the drive for whatever reason now and then.

I have had my new iMac 21.5" for about 2 weeks now. Yesterday I picked up a 500 GB LaCie USB Drive to be used for my Time Machine drive. I have the drive connected directly to a usb port on the iMac. Sometimes when the iMac goes to sleep, when I wake up the iMac I get the dreaded "This Drive Has Not Been Disconnected Properly" warning.
I have made sure that the "Put Hard Disk(s) to Sleep Whenever Possible" option is not selected under the Energy Preferences. I have tried multiple usb ports, same issue. This isn't a constant issue, it just happens sometimes. Is there anyway to tell Time Machine to mount and unmount my drive when needed?

I have a external SATA drive that was used on my old Windows laptop. The interface for the drive is USB 3.0. Whenever i try to view my files on the drive, the drive randomly disconnects, and notifications pop up saying that the drive was not ejected properly.
Also the drive has been reformatted to a Mac format, but it still continues to do this.

Macbook Pro 17" Core 2 Duo 2.33GHz. Following a logic board replacement for a separate issue. I have two external Firewire 800 Hard drives (two separate brands and sizes) which have suddenly started unmounting randomly and giving the 'hardware removal error'. A few seconds after unmounting they mount again, only to unmount a minute later with the error again. It is now doing this in a loop.I have done the following things:
1. rebooted and checked all cable connections
2. I have tried this with the two disks plugged in separately and daisychained.
3. I have tried two separate Firewire 800 cables.
4. running the Disk Utility.
5.installing the system from scratch on a freshly formatted internal disk.
6. reinstalling again with an archive and install.
Everything seems to work fine with a Firewire 400 connection.The only software setting that I changed is to disable the "Put Hard Disks to Sleep when possible" option in the Energy Saver system prefs. Any connection? I have enabled this again and so far (a couple of hours) so good.Should I be looking at a hardware issue

My mid-2014 15" Macbook Pro randomly "loses" its retina display at the top menu (becomes pixel-y), where the battery, sound, and wifi logos are (on the top right side of the screen). A restart fixes the issue, but I want to know if this is an issue that can be fixed?

Why does the eject key only work for whatever's in the SuperDrive? I mean really, a key dedicated just to ejecting a CD? How does that make sense? I eject my iPhone 10x as much as I eject something out of the SuperDrive. What I think they should do is have the eject key bring up a menu of all drives that can be ejected, along with an eject all option. It's a huge pain going to the Finder, ejecting my externals, then going to iTunes to eject the iPod and iPhone.

I've done all the tried and true stuff. I have restarted, I've restarted and held down the shift key, etc. The disc just won't eject. I haven a PM G5 dual core. Should I just shut the damn thing down, remove the drive and get the disc out that way?

I'm a bit frustrated here. My Macbook keeps spitting out my camera software, "Olympus Master 2" CD... It says it's Mac compatible on the CD and in the manual. But everytime I insert it inside of my Mac it spits it out!?

I just finished an install of Windows 7 on my Macbook Pro (2008). Everything works fine, as of now, except that the DVD will not eject cd/dvd. An error displays when ejecting form the sub-menu and the eject key registers the eject graphic on screen but nothing happens. Any one else have this problem? Any solutions?

I've noticed some weird behavior with the Superdrive on my MacBook Pro recently.
My system is
MacBook Pro 2.2GHZ Intel Core2 Duo, 4GB RAM, 200 GB HDD
it's about six months old but gets a *lot* of use.
I notice that the superdrive will sometimes randomly eject a DVD drive after it has been inserted. Last week it took me up to 10 minutes to insert a DVD - I had to keep trying to reinsert it, then I finally rebooted a couple of times and it eventually worked. Sometimes when I bring my laptop back from sleep it ejects the DVD for no reason. I also notice that sometimes when playing a DVD, it will freeze up in full screen mode. I have to hit the power button and reboot as the laptop is completely frozen at this point - this has happened a couple of times in the past few weeks, I think it's related to the random ejects.

I was absolutely relieved, after many painful minutes of troubleshooting, to find in Mac OS Help the section titled "Ejecting a DVD if All Else Fails." I'd never heard of this procedure before, but it sure saved my skin. This is what you do:
1. Hold down the keys Command + Option + O + F while restarting your computer
2. You will be prompted with a white screen that says "Welcome to Open Firmware" instead of the normal Mac OS screen.
3. Type "eject CD" without quotes.
4. CD will eject and the screen will then say "OK."
5. Type "mac-boot" without quotes to finish booting Mac OS and return to your usual startup screen.
You're done and the CD/DVD has been successfully ejected. The above method was the only thing that saved me. I tried everything--and I do mean everything. The darn DVD would NOT eject. So, if any of you are ever in the same boat, now you know what to do. Just thought I'd share this will you all. What could've caused the DVD to get stuck in my iBook? The specific DVD was the Sims 2 DVD game. I bought it used and it was the first time I put it in my computer. After I finally got it to eject by using the aforementioned method, I re-inserted the DVD to see if it would work--and it worked fine. Ejected by simply pressing the Eject key on my keyboard, no problem! What do you think happened that first time? Oh, and if this helps, every time I tried to eject it, I got a message saying that it was in use and could not be ejected. It was not in use, trust me. I waited a long time and the DVD had stopped spinning and the game was long quit.

my iMac ejects blank discs when I try to burn music in Tunes or when I insert a music CD to play it.The disc spins around for about 15 seconds, then it gets ejected. I made sure the surface of the discs were clean and that I was burning from a "playlist," all to no avail. I was successful at playing a movie in iDVD, though, so I'm baffled.

I own a macbook pro, mid 2009 and its superdrive was working fine till 3 days ago. Now, whenever I try to insert a CD or DVD, the drive doesn't read it at all and after 2'' it ejects it. I tried reseting SMC and PRAM with no luck. I also tried that "batmac" trick [hold the mac upside down] with no luck either except my neck is now damaged too..
So, two questions:
1)What could the damage be? It's not a lens thing since it doesn't even try to read the cddvd.
2)My warranty is no longer valid [expired 1 month ago..]. How much would it cost to replace it? I live in Greece and no Apple Store exists here yet. I must take it to my provider [authorized reseller], check it [don't know how much this is going to cost either] and have it replaced.

Is there any harm in just unplugging USB without first ejecting drive? I've got external HD at work I plug in via USB to my Macbook Pro. When I go home I get lazy and would like to just unplug. Is there not a more automated way other than manually ejecting drive before removing cable?

I was trying to import a cd into my macbook pro this afternoon and it went in and clicked into place but then started making a huming sort of noise, but was you could hear it was not spinning, about 20 seconds later it ejected. I tried it multiple times and restarted my computer but nothing seemed to help. The disk drive isn't bent out of shape or anything and I've never had a problem with it until now.
