My hard drive will not eject or allow me to do anything to it

Yesterday I got an old hard drive from 2007 working and began to transfer the files to a new hard drive. About mid way through the transfer there was an error and the new hard drive ejected itself. When I turned it on again it shows up but does not allow me to do anything to the drive. It will not allow me to write to it, eject it, restore it, erase it and all of the files that were transfered do not show up in the finder but it does show that the space is occupied. I tried restarting the computer with the drive plugged in, tried letting it sit for hours and tried relaunching Finder but nothing has worked yet, any advice?

I tried that and it did not work as well. It said:
Error Message
The disk “WDC WD16 00BEVE-11UYT0 Media” could not be unmounted.
Make sure that all applications and files are closed on this disk.
This is with nothing open other than the disk utility and the hard drive within a minute of the drive booting up.

External hard drive will not eject

Since upgrading to ML my small "my passport" hard drive will not eject. First it gives me the message "the disk couldnt be ejected because Safari is using it and to close Safari and try again". (not sure why safari would be using it..) When I close safari then I get the message " the disk couldnt be eject because another program is using it"
My only option is to force eject each time.
Any suggestions?
Thanks

Optical drive will not eject

My Satellite A205-S5814 optical drive will not eject when I press the eject button.
Before this problem started, the drive would eject, but sometimes a blank screen would immediately appear after the tray ejected and then the computer would restart itself and give me the option of restarting in safe mode.
Please let me know what may be wrong.
Thanks.

Your machine is booting into a Windows partition.
Apple does not support Windows. They do provide "Boot camp" which allows a knowledgeable person to install XP in a drive partition on a Mac.
However "boot camp" still in "beta" status and some of the keyboard mapping is not the same as a Windows PC, because it's a Mac, not a PC.
Mac's come with Mac OS X standard, not Windows. The copy of Windows you got on the machine was likely put there for demonstration purposes, not for sale. If you know how to hack Windows, I'm sure you could bypass the admin password, that's a "store trick" to sell a product with a illegal copy of Windows.
All Mac's will open the c.d. tray if you reboot holding the mouse button down with a wired keyboard.
You can also reboot again holding "option key" to select a drive partition to boot from, there should be a Mac OS X and a Windows partition, however it's possible the Mac OS X partition was erased.
You can stick the Mac OS X installer disk in the c.d. tray, close it and reboot holding "c". It will boot off the disk. There you can select Disk Utility from the Installer menu and Erase w/Zero the internal hard drive. When finished Quit and install Mac OS X Tiger. Your "store copy" of Windows will be gone of course.
If your unfamiliar with Mac's, Mac OS X, "Boot Camp" with Windows, I suggest you have someone help you. Your in very deep too early in your learning curve.
You'll really need to learn Mac OS X first, then you can play around with "Boot-Camp" and a legal copy of XP in a drive partition.
With Mac OS X your machine will be very safe from internet threats, but when your in "Boot Camp" under XP, your just like any Windows PC, completely vulnerable.

My WD 2tb external hard drive will not unmount from my MacBook Pro.

My WD 2tb external hard drive will not unmount from my MacBook Pro. It no longer even shows up in finder, however it does show up in Disk Utility. I have tired so many of the suggestions on the internet all to a fail.
I keep getting the message to be sure that all applications are closed before ejecting the drive. I have no clue how to tell which appliactions are using the external drive to shut them off. I turned off Time Machiene to be safe.
I don't need anything on the external drive, I am just trying to erase it, save my current info, and migrate it to my new MacBook Pro.
I have been about four days now with this issue all over the internet, in this community, and watching videos on everything and nothing about this topic to a fail.
I think I am doomed and have lossed this external drive because of some wierd application that will NEVER close on my hard drive for it to disconnect correctly. It's annoying.
Does anyone have a solution?

Have you trie using another USB port? Can you test the USB ports with other USB devices to assure they are working? You may want to reinstall OS X in case there has been a driver glitch.
Reinstall OS X without erasing the drive
1. Repair the Hard Drive and Permissions
Boot from your Snow Leopard Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer.
If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
2. Reinstall Snow Leopard
If the drive is OK then quit DU and return to the installer. Proceed with reinstalling OS X. Note that the Snow Leopard installer will not erase your drive or disturb your files. After installing a fresh copy of OS X the installer will move your Home folder, third-party applications, support items, and network preferences into the newly installed system.
Download and install Mac OS X 10.6.8 Update Combo v1.1.

My granddaughter put the Start Up Disk in the drive inadvertently and now the drive will not eject it or start up using the HD. I have tried all of the suggestions for opening it that appear in the manual. Help?

My granddaughter put the Start Up Disk in the drive inadvertently and now the drive will not eject it or start up using the HD. I have tried all of the suggestions for opening it that appear in the manual. Help? It is her computer, a iMac G3 or G4 with superdrive, the one with the ball shaped base. Thank you.

It's a tray loading drive, there should be a little hole next to it, just large enough for a paper clip. Stick the end of the paper clip in it and the tray should open.

External Hard Drive will not mount after upgrading to Yosemite

After upgrading to Yosemite, my external 3TB hard drive will not mount... can't see in Finder, but does appear in Disk Utility. Follow steps to Repair disk, but get a message that D.U. cannot repair disk.

See mount section.

My external hard drive will not open and only shows up in Disk Utilities. When I try yo repair it, it give me and error of invalid sibling link. How do I fix my external hard drive?

My external hard drive will not open and only shows up in Disk Utilities. When I try yo repair it, it give me and error of invalid sibling link. How do I fix my external hard drive?

Invalid sibling link may not be fixable by Disk Utility. (Disk Utility is very conservative, and will not attempt repairs that might cause you to lose data.)
It is an indication of serious Directory damage.
that leaves
a) third-party Utilities that will take those risks, or
b) re-initializing the drive (which deletes all your data) and restoring from another backup source.
c) "Copying off whatever files you can salvage" has gone by, and you cannot copy anything off a drive that will not mount. You may be able to use "rescue" programs such as prosoft engineering Data Rescue to copy files to another drive, but that sounds a lot better than its reality. You may get many files, but not get ANY filenames.

Disc drive will not eject in Windows 7

I just upgraded from XP pro to Windows 7 home premium yesterday and it's all been working great save one little detail: my disc drive will not eject discs. I've tried the eject button (I'm on an aluminum macbook late 2008) as well as manually ejecting the discs from explorer. When I boot up in OSX I can eject discs fine. It's probably also important to note I'm using the bootcamp drivers that came with my 10.5.6 OSX installation disc, so I don't know if those are up to par for running Windows 7.
Any suggestions would be great

Hi,
I have the same problem with windows 7 not ejecting discs (with macbook pro late 2008 with latest Bootcamp drivers installed).
At the moment I can eject the dics only by putting windows 7 to sleep (closing the lid) and on wake the disc ejects by pressing the normal Eject key.
Hope apple (or MS ??) will fix this...

My Hybrid 1TB Seagate Hard Drive will not work in my data doubler caddy installed in the optical bay

My Hybrid 1TB Seagate Hard Drive will not work in my data doubler caddy installed in the optical bay of my MacBook Pro

Thanks for all the advice. It looks like I have finally got my MBP working again (after two weeks of pain).
The WD HD works fine internally, but restoring from TM introduced a whole load more of issues/incompatabilities (see above). Eventually the only thing left was to re-build rather than restore:
i) mount the WD disk internally and install Snow Lepoard from the orginial installation disks
ii) get online, and after much trying download Lion (previously purchased). Perfrom all update.
iii) Connect my Time Capsule, identify my data, photo and music files and then copy them accross by hand
iv) install all the other applications (e.g. MS Office:mac, etc) from scratch.
This exercise has shown me that even though tools and procedures exist to address separate issues, when the complexity of inter-dependence is introduced there are a raft of problems that crop up.
Now I am back in business I will be using TM and CCC to take full and regular copies. I did this previously, which has saved me from losing my data and cherished pictures, but hopefully next time (and I'm sure there will be a next time) the recovery will be less infuriating.
BTW I got a refund on the Seagate Momentus XT. They guy in the shop said it wasn't the first time he'd heard of this issue with MBPs. Great.

Problems re-installing PSE10 using disks. Disk drive will not eject. [was: Question]

A virus fried my PC and I am re-installing Photoshop Elements 10. When prompted to install Disk 2 the disk drive will not eject. I have to uninstall Disk 1 before it will eject.

There is no question in your posting.

I recently updated my Mid 2007 iMac with the latest OS 10.8.5 now my external hard drives will not show up. They show up when I boot them up on a machine running and earlier OS. Is there a fix for this?

I recently updated my 20-inch, Mid 2007 iMac with the latest OS 10.8.5 now my external hard drives will not show up. They show up when I boot them up on a machine running and earlier OS. Is there a fix for this?

Can you see them in Disk Utility?
If so, can you select and Mount them?
If not, disconnect them, reset the iMac's SMC and then reconnect them.
Intel-based Macs: Resetting the System Management Controller (SMC)
1. Shut down the computer.
2. Unplug the computer's power cord.
3. Wait fifteen seconds.
4. Attach the computer's power cord.
5. Wait five seconds, then press the power button to turn on the computer.
If you still can not see them, connect them back up to the iMac running the older OS, open Disk Utility and look to see how they are partitioned and formatted.

Lacie 500GB Porsche USB 2.0 external hard drive will not sleep

Hi there,
I bought a Lacie 500GB Porsche USB 2.0 external hard drive that shipped along with my new iMac. I have noticed that even though I check to "put hard drives to sleep" when not in use under system preferences, this hard drive will never sleep. I have to eject it and then turn the hard drive off. Anyone know how to fix it or know if it is a Leopard or Lacie issue that might be fixed with a driver or firmware update?

Hi,
I just got the same drive and was wondering the same thing. I inquired with LaCie about it and here is the response that the support people gave me:
"That particular unit does not sleep. We changed the bridge to the newer controller, which is faster and better for data transfer, but that feature was dropped from the design. I'm sorry."
Hope this helps.

Hard drive will not mount shows up in Disk Utility

I have an external drive with a bootable OS X 10.6.8. I was in a transition between building up a SSD swapped drive. The SSD is installed in the CPU box but I have my old installation running from an external.
I have several external hard drives. They are all Firewire. Some have USB 3.0 and or eSATA options but my MacMini only talks to Firewire and USB 2.0.
I understand that you daisy chain Firewire drives and turn them on and off in sequence as they fall from the CPU box/case.
Firewire is a power source. I run the external with the OS using an AC adapter but one Firewire drive is powered through Firewire.
I have had as many as 4 external drives running along with the internal drive without a glitch while I was reorganizing files.
Today I booted off the external drive. It was running fine. I turned on one Firewire drive (the one that runs on Firewire power). That drive stumbled. I recognized the sound when there is an interruption in power. This cause the external boot drive to stall. I had to force a reboot.
Now the external boot drive will not boot up. It does not mount but Disk Utility sees it. The drive itself is bright and clear in Disk Utility but the partition (single) is faded out. I can run Verify and repair in DU. DU says it doesn't see anything to repair. It will not mount on its own or when I click the Mount button in DU. It does not produce an icon on the Desktop (because it is not mounting).
I also have SpeedTools. But although it sees the drive I cannot do anything with it. None of its tools run more than a spli second before they fail.
This drive has USB 3.0 and I see everything through USB that I see through Firewire. Connecting the other way did not get around the problem.
Of course I will buy an AC adapter for every external drive and never run them using Firewire again but the horse is out of the barn.
I have the original installation disks and could run the Archive and Install option but it would require physically swapping drives with the internal. I'd like to avoid it if possible. It is a MacMini and tedious.
Any suggestions?

I took the problematic hard drive and installed it in my Mac Mini so I could attempt a Safe Boot and then Archive and Install if necessary.
Safe Mode didn't work. The drive produced the circle with a slash symbol.
I reset the PRAM which was part of a list of steps to work through I found created by Apple Support.
I was able to boot up to Verbose Mode and view the text of the boot process. I wrote it all down. I can answer questions about the content better than typing it all out exactly. It includes, "...journal magic is bad..." "...failed to open..." and ends with "...cannot mount root, errno = 19"
I attempted Archive and Install however when it went to show what target drives were available it was a blank box and all buttons were grayed out.
I rebooted and opened Disk Utility from the DVD. The drive appeared the same with the top main line bright and the partitioned volume faded. Still was unable to mount. I ran Verify and this time a red line of text appeared "Invalid content in Journal" and at the end I ran Repair. When running I could read line by line and at one point it showed "checking volume information" then the following line "Repairing volume" the following line "Rechecking volume" more line of checking then it ended with "The volume was repaired successfully."
It still would not mount. I ran Verify again and again said "Invalid content in Journal" and this time it stopped midway saying "The volume was found corrupt and needs to be repaired. Error: This disk needs to be repaired. Click Repair Disk."
I clicked Repair and it ended with The vol. was repaired successfully."
Still unable to mount I began repeating Repair over and over. Each time it found something to repair and ended with a success message. After several more Repairs I tried Verify and it stopped midway saying to Repair the disk.
Question: Does running Repair multiple times continue to correct bits and pieces little by little or is this a generic message and we should treat it as a problem Disk Utility cannot pinpoint and is just beating its head against the wall?
The step by step instructions I downloaded mentioned running Repair more than once but it did not say that running it 20 times would erode some problems and eventually lead to a fully repaired disk (if the problem was something DU could take care of in the first place). At this point I have run Repair about 20 times total with a series of 10 back to back skipping Verify. I keep seeing the lines about invalid content in a journal and that it repaired something successfully. Yet I still cannot mount the disk.

Hard Drive will not Mount

I have a Seagate Barracuda 1.5 Gig installed in a MacPro as an additional drive and as of today the drive will not mount. Yersterday I noticed it ejected itself; I immediately rebooted and started to download the data to another drive but it ejected itself again after about 25% complete copy. I attempted to "verify drive" with Disk Utility but it was not listed. This morning it will will not mount. The drive is still under warranty so replacement is not an issue. Where I am at a loss is recovering the data. I fired up time machine and there was no data from this drive backed up (Bay 2). I checked the preferrences and the drive was not "excluded". So, I'm at a loss as to how or if I can recovery any data. I removed the drive from the MacPro and fired it up in a docking station (SATA) without results; still will not mount. Is recovering my data beyond hope? Any ideas or tips would be appreciated.
Thanks,
Koyangie

Hatter,
Tried Recovery Mode without success. Although the drive appears in Disk Utility I get an error after selecting Restore! If I click on the Image icon it will not list the contents.
There is perhaps .6 TB on this driver (images). After I posted and received yourt reply I took another look at my Time Machine and found all my data under Shared. What a relief.
Thanks for your advice. I'll return the drive to Seagate for a replacement. Hopefull I will be able to format it before sending it back.

After security update my hard drive will not show

G4 Tower - Mac OS X - 733mhz.. After a security update 2 days ago i can not get my computer to boot. It comes up to the gray apple screen and just sits there. I put the install dvd in and went to disk utilities, but the hard drive does not show up at all. I tried to boot the computer in target mode from my laptop. It goes into target mode, but the drive never shows up on the screen. I put disk warrior in the laptop and launched it, and it seen the drive as a firewire drive, but the only option was to rebuild. I have a lot of info on the drive, and am hoping that I do not have to go to that extreme. Please help...

the only option was to rebuild. I have a lot of info on the drive, and am hoping that I do not have to go to that extreme. Please help...
I think you are misunderstanding what disk Warrior will do, and how it does its magic. Disk Warrior is a wonderful, powerful, tool and works well for many people. When it suggests a ReBuild, it is saying your drive is recognized and intact enough to attempt to construct a new (proposed) Directory.
It will scavenge all the information it can find from every possible source (including the existing Directory) and build a new (proposed) Directory of all your recoverable files. If the damage is not severe, nearly all your files will be included in the new (proposed) Directory.
It then lists the differences between the new (proposed) Directory files compared to the old (existing) Directory files, and invites you to look at them side-by-side, if you like. ONLY if you approve, will it replace your old damaged Directory with the new (proposed) one. If you choose not to replace your old Directory, it just quits and nothing is changed on your Drive.

My hard drive will not eject or allow me to do anything to it
