USB external drives won't eject

Since the upgrade to Mavericks my external USB drives will not eject normally, only by using force eject.

Thanks that did the job, nothing was showing open so I was just trying to figure out what was open but logging out and back in did it. thanks

USB LaCie Porche 500gb usb external drive won't mount

Here is the scoop.
A few days ago I was using my LaCie 500gb external drive and the usb chord was accidently yanked out whilst adding a photo to iphoto.
So i thought uh oh better close everything disconnect wait a while then restart.
So I did...plugged it back in...it made all the normal start up noises little amber light came on but it didn't appear on the desktop..nor in disk utility. But it did appear in system profiler.
Yesterday after resetting the "pram" or whatever it is that happens when you hold p + r + the apple key and alt....or ctrl and still no relief.
So i leave it plugged in over night to see if it is merely slow for some reason. When i awake this morning it is in disk utility even with the "time machine" volume...so presumably all the files are more or less still intact. But it still isn't mounting. So after clicking repair disk ....three or more hours later i get this in the log

Any ideas people.

nonononon...
Every tech will offer to reformat the HDD or suggest its broken.
The table of contents are corrupted.
What I do is remove the drive from the case and put it in a PC and run "mac drive" software then choose repair volume and your good to go.
Iv done this as a PC tech for several of my mac customers.
But for the life of me I cant appear to reproduce the issue and don't know what the issue is.
Several macbook guys have given me their "broken" USB drive and the TOS is corrupted. Its really a royal pain in the back side.
What is the issue, how to make it stop?

Apple USB external drive can't eject CD

I have a 27" iMac and am having trouble starting up. So I tried starting up from a Techtools CD in the external drive (there is no internal CD drive on the iMac). Unfortunately the iMac would not start from the CD and the CD is now stuck in the external drive.
Pressing the eject button on the keyboard while trying to startup does not eject the CD. I tried connecting the external drive to a 23" iMac but it would not recognise the external drive.
As for my startup problem I tried a PRAM zap but the startup still hangs and the iMac tries to restart again after a little while.
I tried starting up holding down Cmd + R which I think is the recovery system but the startup still got stuck.
Any ideas on how I startup and/or get my CD out of the external drive?
Thanks

RRalph Landry1 helped me get my stuck CD out of my external drive by suggesting in a post on 19 Jan 2014 to hold down the mouse button or trackpad while restarting the iMac. It worked and the CD ejected.

My external drive won't eject. should I shut down my computer? It says if I force eject, I might lose info stored!

My exernal drive will not eject. Should I shut down my computer? It says if I force eject I might lose info!

Hey I typically have this problem as well. For starters what steps have you went to to eject the drive? Have you just done it from finder or have you gone to the Disk Utility and tried to eject from there as well? If not then I would recommend this first. I would also recommend before doing anything to save any neccessary information that was placed on the drive locally if possible.

WD My Passport 1TB USB external drive randomly ejects from my iMac and MacBook Pro.
The drive is approximately 4 years old. When the drive is plugged in, I can see the data. It appears to be working properly. The only problem is that everyone of my Apple Machines are ejecting it. Several years ago, this drive connected to Mac machines with no problems. I have tried two separate USB cords. I have updated the firmware. I have tried it on my MacBook, two different Macbook Pro's, and my iMac.
All give the same result of random ejection of the drive and the error message of:
Disk Not Ejected Properly
Eject "1TB Passport HD" before disconnecting or turning......
Searching through the web, it seems this is an common/known problem. Does anyone know the solution?
Thanks,

Send Apple feedback. They won't answer, but at least will know there is a problem. If enough people send feedback, it may get the problem solved sooner.

USB External Drive Backup & Erase Woes

I have been using a Lacie 500GB USB external drive allocated as a backup disk for time machine. Over the last couple of weeks, the disk has been spontaneously ejecting itself from the desktop. This could happen when not backing up to time machine, or during the backup.
I am not a daily time machine backup-er, as I don't have much to backup on a daily basis (and I weekly backup to an alternative disk using Super Duper). What I had noticed with the time machine disk, is that the preparation prior to the backup beginning was a massive 40+GB, certainly not the amount of data which would have been 'new'.
To try to resolve this, I have used disk utility to verify the disk, and the snow leopard disc to check my boot disk on the Macbook Pro... there has not been a problem identified with either.
Today, I decided to erase the time machine disk, zero the data, and re-allocate the drive for time machine backup. After setting these preferences in disk utility, and clicking 'erase', the disk again erased itself, with the error message :
'Disk erase failed with the error: Assert: internal error, or unimplemented'
I then had an external disk which was not present on the desktop, and apparently in some sort of limbo between erased and mounted!
I was able to do a simpler format function on the disk via disk utility, the disk will mount, but the allocated disk space previously used by time machine is still present, and the format has only done that remaining space on the disk.
Anyone know what the above error message refers to, am I able to reformat the disk using the 'zero function', or has the disk failed and become unrecoverable?
Answers / suggestions kindly welcomed.

Welcome to Apple Discussions.
When you use Disk Utility to erase totally you need to click on the LaCie drive name not the name that appears on the desktop. Select how many partitions you want and give each partition the name you want it to have and perhaps also the partitioning scheme and other options that are available, then erase.
Doing this will of course make all that is on the drive unavailable to you.
These are LaCie's directions for their drives.
Some LaCie drives might also have firmware updates available - worth a check on their website.
Note that LaCie seem to have 2 yr warranty on their drives, at least the one I looked at on their website. If the drive is younger than this you might have a warranty claim.

External drive won't mount after plugging in iPhone - MacBook 13'' (2,1)

Hi Support Crew...
I have a 13" MacBook(2,1) running OS X 10.6.2. This is a 2 GHz Intel Core 2 Duo machine w/ 4 GB RAM & 320 GB hard drive.
Today, I had the Iomega drive plugged in via USB, along with my soundcard (MOTU 828mk2) plugged in via FW. This is a very normal setup for me which has been bug free since I bought this computer over 2 years ago. When I plugged in my iPhone 3G via USB I got an error message which comes up when you incorrectly remove a device. This was strange because I didn't unplug anything, I only plugged in the iPhone. The iPhone was playing music when I plugged it in and I had to unplug and plug is back in to get iTunes to recognize it.
Ever since this happened, my Iomega external drive won't mount. I am able to access it via Disk Utility (and ran the Verify Disk/Repair Disk - everything is "ok"), however I can't access the data on the drive. I really really need the data but of course can't access it to backup.

The fact that I got the "Improperly removed device" error when I plugged in the iPhone makes me think something weird is up and it's not actually the external drive. There is clicking/whining/noise, the drives powers up fine and is recognized by the system but the mount point is now "not mounted".
Does anyone have any idea how to fix? If you live in SF, I will buy you a beer.

I meant to say; "There are NO clicking/whining/noise sounds made by the external hard drive"

USB external drive not readable by mac but readable by windows

Hi, I have a usb external drive (Seagate FreeAgentDesktop Media) which works fine with windows xp but cannot be read by the mac. I reinstalled the mac a couple of days ago because it was being very slow and I had a bunch of junk on it. Anyway, after that, it won't read the external drive. It will give me an error message saying that the disk is not readable by the computer. Sometimes it will give me the message saying that the drive was unmounted improperly by windows and for me to unmount it correctly. When I go back to windows, it's there, then I restart and go back to mac, it'll give me the message that the disk is not readable. I have 2 of these drives and both of them have this issue. I also tried disk warrior but it says that the file system cannot be rebuilt. I tried USB flashdrives and they work. I got all the data off of one of the external drives into the other and I couldn't format or even erase the drive because it says that the permission was denied. However, I could format it and erase it with the installation DVD. But I had the same result no matter what format they were in. I have very important data on these drives and I really need to be able to use them with both operating systems. Thanks a lot!

Hi Schmerz Meister;
If DiskWarrior say it can rebuild the disk about your only other alternative it to reformat it.
This will of course destroy all data on the disk so make sure you have copies of the data elsewhere,
Allan

Optical drive won't eject and can't power off from Apple menu!

I have a Quicksilver that has almost always acted great but ever since I physically moved the machine to another room I've been having intermittent problems. Here's a quick summary:
-Overall more sluggish performance
-Occasionally the optical drive won't eject and I have to restart the whole machine. (I did replace the drive a couple years ago but have never had any problems until now).
-I can no longer shut down/restart from the apple menu, i have to push the power button in.
I used to get device removal error messages at inappropriate times but that seems to have stopped since I reseated my USB 2.0 card. Here's a list of the other remedies I have tried:
-Repair permissions
-Make sure all cards/RAM seated properly
-Replaced PRAM battery (year was displaying 1970)
-Ran DiskWarrior
-Re-imaged entire boot drive
I can't remember if I've tried zapping the PRAM because this problem has been going on for about five months. None of this was an issue before I carted the machine into another room so hopefully I haven't dislodged anything. Also, I notice a lot of static build-up in the room despite the hardwood flooring. Perhaps that could be an issue and if so, any suggestions?
I was dreading that it could be my logic board, any advice?
thanks,
Jesse

Well....it may be fine for you to accept an inferior item, not I. I paid for a unit that was supposed to be fully operational and work as designed. I will not accept having to reboot every time I want to put a CD or DVD into my computer! That's like having to restart your car so the headlights work. Even if one doesn't drive at night, you would still expect the headlights to work ANYTIME you want them without the extra steps. I know "where" the issue is and I know "why" the issue is BUT unfortunately, there is not a fix I can find. Between uninstalling and reinstalling drivers and applications and etc. I give up. They will replace my unit according to Lenovo, with a brand new laptop. Should this one have the same issue, I will be disputing my CC charge, and sending the unit back to them for a full and complete refund. I wish I had a copy of WIn8 or Win7 without Lenovo's proprietary software embedded. I bet the unit would work as designed then, but to have them rewrite or add software with hooks directly into the core system is a recipe for disaster. I encourage you to do something about yours also. The more people that ALLOW this "type" manufactured fleecing, the more it will occur.
I guess I will find out just how well this replacement process works.

MDT 2012 deploy OS from USB external drive failed - need to unplug and plug it once again

We are using MDT 2012 and deploying Windows 7 using media (USB external hard drive). We can successfully deploy Windows 7 32 bit using this method but there is a problem with deploying Windows 7 64bit. This problem appears only on HP EliteBook 840. We can
boot into WinPE 64 bit and can start proper task sequence, all image is applied then after restart, before logon screen appears there is an error saying that cannot find litetouch.vbs script. After clicking ok, I can logon to Windows and there is no usb external
drive recognized. But when I unplug and plug usb drive once again it is recognized by Windows and can be used. I can see that Windows install some drivers just after plug it again
I checked BIOS looking for some USB power options - there is no such settings. And 32 bit deployment works ok. So this is not a case. Looks for me like a problem with proper usb drivers for 64 bit. I download all drivers from HP website (driver pack and
drivers only for USB 3.0). We are using make and model matching in MDT - works ok for all the rest hardware models. Any idea how to troubleshoot it?

Not sure what's going on here. Is this a USB "Flash" drive or a USB "Hard Drive". There *Is* a distinction.
I *thought* that MDT would copy itself to the c:\minint\scripts folder to continue installation.
Next time, when you see this error, Press Shift-F10 to get into a cmd.exe prompt. Can you find litetouch.vbs on any of the drives? Does the USB Drive appear?
IF in fact, the USB Drive is not appearing after the 1st reboot, then you have a problem. Why did the USB 3.0 driver not install. Check the Driver Installation Logs to verify.

Using a usb external drive with logic

I have a 500 GB Lacie usb hard drive which I'm currently using just to backup my system. (Still on Tiger by the way.) I'm in an older intel iMac (1.83. 2 gigs ram, 250 gig internal hard drive). After installing LP 8 and all the bells and whistles on the internal drive I now have less than half of my internal drive space available. My logic project files are there as well. Not a big problem but I'm trying to look further down the road... Usb drives are slower than firewire but my projects are relatively simple. I don't record more than 2 tracks simultaneously and rarely exceed 24 tracks total for a song. Two questions. First can I get by with my usb external drive? And second how do I move my projects onto and external drive and still have logic know where they are? Thanks

I have the oldest macbook (1.83. 2 gigs ram, 60 gig internal hard drive)
I have all my logic content on my external maxtor firewire 400 drive (usb 2.0 is actually faster than firewire 400) and everything is fine. the good thing is if your external drive has 7200rpm, but the ones with 5600rpm should do as well.
Once you drag your apple loops to logic from your external drive, logic will remember for the next visit. And when you are opening a project which is on the external drive , just find it with logic finder and all should be fine.

Problem mapping USB external drive connected to Airport Extreme on my PC

I am having a problem mapping my USB external drive in my PC running WIndows Vista. Here is what I have so far:
USB External Drive connected to my AirPort Extreme which is connected to my Century Link modem/router.
I have installed the USB drive using the Airport Utility. In the Disks section the Enable File Sharing is checked, Secure Shared Disks is set to With a Disk Password, I have entered the password in the next 2 rows, and finally AirPort Disks Gues Access is set to Not Allowed. The section below named These Settings Configure Windows File Sharing is empty. Am I supposed to put something here?
I was also told I need to map the drive in my PC, but when I go to do that via the Computer and the Map Network Drive, I get stuck where it asks me to enter a folder name. I read many of the posts which tell me I need to enter among other things the disk's ip address, but I am unable to find it anywhere. Where do I find what to put here?
Can someone please help this frustrated user?

I had my USB drive on my APE working with Time Machine under 10.5.1 very reliably. A few days ago however, I needed to suspend a backup operation, and when I came back to restart it, time machine refused to mount the disk image on the drive. After several attempts to get it to connect with no luck I decided to delete the image (the sparce image file) and start over. Now TM refuses to create a new image.
BTW, on the Mac OSX hints site there have been suggestions to start a backup with the drive directly connected, then stop the backup, move the sparce image file to the root of the drive, reconnect the drive to the APE base station to get it working. I tried this again, but I think Apple has changed something in 10.5.2, because when directly connected TM no longer creates a sparce image file.
Anybody else seen this behavior after upgrading to 10.5.2?

Boot Camp with Win 8 Can't See The USB External Drive [MBR with NTFS, Fat32, HFS Partitions]

Hi. When I boot to Boot Camp with the latest Apple Windows Support drivers can't see my USB Flash Drive, DVD and OS X volumes but not my USB external drive that has an MBR partition scheme (using iPartition from GUID) and in there it has different volumes [HFS when I boot to Snow Leopard, Fat32, NTFS]. What can I do with Boot Camp to make it see my USB external drive and why isn't it seeing the USB when it can see the USB flash drive both use USB?
Thank you in advance.
God bless.

Imovie9, 13"macbook aluminum and USB external drive

I know firewire is better, but is it totally impossible to use USB. Others have said its ok. Tom Wolsky on the FCE forum said that many people are returning the macbooks without firewire. I did a search on other discussions and some say its ok, while others say no.
Please do i really need a macbook pro or a white macbook. I will be editing HDV and eventually AVCHD.

Thank you! Yes. I have HDV today with an imac. I am deciding between the new macbook and the new white macbook. I really want the small form factor. I should really just buy the white one since it has firewire, but I don't want plastic and i like the new touchpad. I also want to get a flash drive HD camera that uses USB. I got concerned using a USB External drive for the AVCHD because of file sizes and making the USB drive unstable. I think i will ensure that i keep enough hard drive space on the macbook to do all editing and then move as much as I can to the external drive.
