Improper Western Digital ejection fix?

I have a Western Digital Hard drive that I accidentally ejected without unmounting. Now, in an attempt to fix the mess up I rebooted my computer, and unplugged the hard drive and reinsterted it. When plugged it in again my computer recognized that there was a hard drive plugged into the USB port but it wouldn't mount. I took the following actions on advice of this forum and none worked.
1.) I tried resetting the PRAM on startup.
2.) Ran disk utility and tried manually mounting the drive. Since it was unmounted I was unable to repair disk permissions.
3.) I read another help article that said there was an unsupported launch daemon placed on the Mac HD by western digital drives, but the supposed launch daemon was not in the folder.

grimacebrown,
There's really nothing mysterious about the items you deleted using the PC. Those are simply normal files and folders, which are usually hidden by default (even in Windows, but many people turn on "Show hidden and system files").
Also, nothing mysterious about why the drive wouldn't mount after improperly disconnecting it. Doing so is likely to cause disk errors, and in this case, it did. Disk errors are funny things, and can sometimes cause a volume to not mount, sometimes not. As you have found, it can also be specific to one platform or another. Sometimes, a volume with a disk error will mount, but only after several minutes or longer (an hour? Two?).
Removing those potentially "corrupted" items has obviously made the volume mountable, but the disk error probably remains. I recommend you use Disk Utility to at least verify the drive (not permissions; check the disk itself). If errors are found, they might be "fixable" by Disk Utility.

  • Western Digital woes... please help!

    I have been doing research for the past hour on various postings, but I can't seem to find an answer or solution.
    I am a filmmaker/editor, with my documentary film on 2 Western Digital 750 gig Pro Edition drives. Last night, as I passed by my iMac, I noticed there was a "Disk Cannot Be Read" error message that popped up on the screen. The one Western Digital drive that I had plugged in was no longer mounted. The message instructed me to "ignore" "eject" or "initialize." I clicked on initialize, it brought me to disk utility, I tried to run repair disk, and I got all crazy kinds of error messages. So, I tried this with the other Western Digital drive, and got the same message. And then I started to freak out.
    I tried to mount the disks on my G4 PowerBook, but-- same thing. If I tried to connect via USB 2.0 (there's no regular USB on these drives), I could find the drives in Disk Utility, but they'd be grayed out, so I couldn't click on them.
    To add more of a headache, I purchased a 1TB Western Digital Studio Edition Drive to use as a Time Machine backup, about a month ago. I haven't opened the box yet because I've been busy, but now I'm reading all these posts saying that people are having a problem with this model, as well. I purchased it from MicroCenter, which states that it has to be returned within 30 days. Today is 11/23, and I bought the drive on 10/19. Of COURSE!!
    Anyway, is there ANY solution to this?? My drives have never been dropped or subjected to a power outage. I'm pretty neurotic about always safely ejecting the drives, so I know that's not a problem. I just want to have my hard drives back, and most of all-- my film footage!!
    Any advice/tips would be GREATLY appreciated!!

    Hi Nerowolfe,
    Thanks for your quick response. The drives are indeed Firewire 800/400 drives, but they also have USB 2.0 on there. I always use Firewire 800 to transfer data, but in reading other people's postings about Western Digital drive issues, they suggested that the only way to "read" the drive after receiving one of these error messages is to connect through the USB port, rather than FireWire. My disk was still not mounted when I tried USB, but it was able to see it on Disk Utility, where I then performed "repair disk" and then received the disk error message.
    What I'd like is for there to be some kind of software update on Western Digital to fix this-- they seem to have made an update for the Studio edition (that's what my 1TB is), but not for the Pro Editions (what I have), and that's where all of my media, unfortunately, is stored.

  • When display turns off system improperly ejects Western Digital external hard drive. Yosemite 10.10.2

    Why does computer improperly eject my Western Digital (My Book for Mac) external hard drive when display turns off. And how do I stop this from happening.

    Your External Western Digital usually has Utilities from the company that can be downloaded from their site@http://support.wdc.com/product/download.asp?groupid=133&sid=157&lang=en
    run their scan for errors and post back. Also do you have Time Machine always running at time of incident?

  • Western Digital USB3 external hard drive (attached to new MBP Retina) seems to randomly "eject" itself when I'm trying to back it up via time machine. When this happens, I can't even shut my machine down properly. Ideas?

    The backup process will run for sometimes 30 minutes or more. But, it's as if, at some point, the drive just can't be found. I get the message "this drive was ejected improperly". When this happens: my machine won't shut down, disk utility won't run. I have to press and hold the power button to force a shut down. Any ideas what's going on here? A MBP Retina issue? A USB3 issue? A western digital issue (although this drive has been functioning fine on old MBP)?
    Thanks!

    When you say that you've applied the latest 'patch,' I'm assuming that you mean the latest (July 18) software update for mid-2012 models? It was supposed to address some of the problems with the USB 3.0 ports. I don't think that, in most cases, it's a problem with the drives themselves (USB 2 or 3), rather it seems to be a port problem.
    If it wasn't fixed for you using the July 18 Software Update the only thing I can recommend at this point is to see if Mountain Lion - soon to be released - will be able to fix the problems. If not, I would take your unit back to the Apple Store and let them know that you are continuing to have problems with the USB 3.0 ports. They may offer to switch out your logic board, etc.
    Good luck,

  • Western Digital External Hard drive keeps undocking when running time machine.

    I have been using a 2TB Western Digital My Book external hard drive for about a year now to run time machine and backup my files. The past month I have noticed that my backups have been failing. I try and for a backup and about halfway through it gets "delayed" because of an error. Then I have a alert pop up on my desktop with the following message:
    The disk was not ejected properly. If possible, always eject a disk before unplugging it or turning it off.
    The disk was not unplugged from the power supply or the usb port. I am stumped. Anyone know what is going on and how to fix it??

    I would avoid WD, Seagate, LaCie, and Iomega external drives, and any drive with special features such as networking or built-in backup software.

  • Western Digital MyPassport 1TB not recognized

    I have had a Western Digital MyPassport Essential (1TB) for a little more than a year now. I'd been using it fine with my Late 2008 Aluminum Unibody MacBook. This August, I purchased a MacBook Pro with Retina Display and now the drive rarely (if ever) shows up when connected. I've tried uninstalling and reinstalling the drivers, plugging it into different ports, and nothing works. Yet, when I try to use it with another computer it works fine.
    Has anyone else had this problem/know of a fix? I ordered a new USB 3.0 cable from Amazon, so maybe that will solve the problem, but I'm looking for a solution in the meantime.

    its not the cable, its the SATA card thats failing.   Seen it a 1000 times,  that part is a stinker and as sure as sunrise
    junky 50 cent SATA bridge/card in an external HD
    **When you plug it into another computer and find that it works but works only sporadically on your primary computer, thats also indicative of a SATA card failure, hence the "haunted hard drive syndrome" name given to the strange nature of external HD behavior. It often makes no logical sense what is going on when your HD cant be logically diagnosed due to odd behavior.
    External HD are very easy to diagnose. Bad USB cable (on commercial sold USB drives) almost doesn’t exist anymore.
    External USB HD have 4 'parts' (not counting the HD internals)
    1. USB cable (never an issue anymore, approaching 100%)
    2. HD enclosure.....a plastic or metal box which cannot ever be an issue.
    3. the HD itself   (which will either fail or make noticable 'going bad' signals)
    4. ....and last but not least is the epicenter of 'weak links' ,.....a SATA card/bridge that is connected to the HD inside the HD box, the size of a stick of gum, with SATA female on one side, and female USB on the other side, containing circuitry for data transfer between the SATA on the HD and to USB on the other.
    While these bridge cards are better than they used to be, theyre still insanely unreliable.
    There are literally probably MORE than 100,000 perfect external hard drives out there thrown away every year because people assume the "hard drive is bad" when really they could crack open the HD enclosure, remove the HD and put the good HD into a new enclosure.
    See this video of the SATA CARD, its at 8:55min. http://www.youtube.com/watch?v=2pS_EDsP2KI
    All conventional HD external are nearly 100% like the video above.
    This  nasty piece causes very odd behaviour, some have called it "haunted hard drive syndrome".  Random ejects, random strange vanishing of the HD , especially in mid transfer of data.
    the card attached to the TOP of the HD plugs in, that the SATA bridge

  • Western Digital My Book (white light) not connecting...need advice

    Hi...I have been scouring forums for the past hours trying to trouble shoot this issue.
    At one point (it may have been with Leopard) I was able to back up all my pictures and music onto my WD MyBook. It showed up in Finder. In fact, when in Finder I GO>>CONNECT TO SERVER....My Book is listed as one of the recent servers. However, when I try to connect it cannot find it.
    I tried the Safari Bonjour...MyBook is not there either.
    I have reboot my computer.
    I have reboot the MyBook.
    I unplugged the MyBook and the router (Airport) for 30 seconds, then plugged it all back in reconnecting.
    I pressed the little reset button the MyBook.
    No connection. Both the top and bottom bright white lights are illuminated and not blinking or anything on the MyBook.
    Help....this was the 1TB external hard drive and I really don't want to just give up and spend another 200+ on a new external drive. Luckily my mac has behaved and I don't necessarily need my backup files...but I want to have a reliable backup in case something does happen. I am a photographer so backing up my many many files is necessary.
    Any suggestions? If there is no way to fix (which is what I gathered from some of the forums I already visited)...then what other system besides western digital can you recommend? Apple is super expensive....Iomega seems decent, and also LaCie...but then again, I thought Western Digital was good too. Help....

    Pondini will probably have my head, but I'll go ahead with my suggestion anyway:
    1. Because WD drives (enclosures) are not the most "trouble free", I'd seriously consider getting another external drive such as a LaCie or one from OWC (madsales.com).
    2. I personally have chosen not to use Time Machine; I don't like it because I can't boot with it and I don't feel it is very reliable either, so I'd suggest downloading either SuperDuper or CarbonCopyCloner (I use both). Install it in your Applications folder. Open Disk Utility and - either with your WD or the new drive attached - format the drive (click on the partition tab):
    Choose how many partitions you want  (one or ?) and name each one.
    Choose Mac OS Extended (Journaled) format.
    Under Options, choose GUID partition scheme (necessary to make it bootable).
    Click Apply.
    NOTE: this will erase all contents, so if you have anything on it you need, temporarily copy if elsewhere via drag 'n drop.
    After it's finished, open CCC or SuperDuper.
    Choose your internal as the source.
    Choose the external (partition) as the destination.
    Click on copy.
    When finished (my 80 GB takes about 40+ minutes), test it by going to Startup Pane in System Preferences, choose the external clone and click on Restart. If it does, all is well, and you can go back to restart with your internal. Once back on the internal, you can eject the external and unplug it/turn it off.
    You now have a fully bootable clone of your entire system.
    I update mine about once a week (that is all I need) - you can do it more or less often.
    Now, I maintain two bootable clones because hard drives can (and will) fail at any time. So, you could do a Time machine backup on the other one if you want.

  • Western Digital MyBook Studio no longer works after Yosemite update

    A little while ago (Jan 30) I updated Yosemite, and now my Western Digital My Book Studio (using firewire) shows up but no longer works - no Time Machine, or Super Duper back-ups. Does anyone know why this has happened, and what can be done to fix it?

    I should add that the drive works fine with another MBP running OSX 10.6.8. Again, with 10.10.2 it either doesn't work or is incredibly slow.

  • Hard Drive (western digital) no longer mounting..?

    Hi guys.
    I have yet to find any resolution to a new problem I've been having with my Western Digital Hard Drive.
    I've had it for about 6 months. Has run with no problems, until recently.
    I have been running it on my Macbook Pro 2.66 GHz Intel Core i7 and Playstation3 since I bought it. I went to load up my Macbook one day, and it would not recognize the hard drive. I have run the Disk Utility repair/verify options on it. It shows up on the list, when I select eject, nothing really happens. It just stays on the list. When I select the particular partition (FRANK) on the hard drive, and click Mount, I get an error message stating; 'Try running first aid on the disk and then retry mounting.' Which I have done, and this is what I recieve;
    Verify and Repair volume “FRANK”
    Checking file system** /dev/disk1s1
    ** Phase 1 - Preparing FAT
    ** Phase 2 - Checking Directories
    ** Phase 3 - Checking for Orphan Clusters
    28027 files, 424337248 KiB free (13260539 clusters)
    Volume repair complete.Updating boot support partitions for the volume as required.
    I have plugged the HD into an iMac in the house, and it mounts no problem and all the files are there and accessable.
    When I first had this problem (2 weeks ago) I decided to back everything up on the iMac, and format the HD, just to see. And again same issue, even after formatting it, FAT 32 (MS-DOS) - For Playstation.
    Any ideas on what I can do to be able to access Frank again, from the Macbook Pro?
    Thanks for any help!

    I had a similar issue with an Iomega hard drive after connecting it to a samsung led tv
    the resolution for me was to boot into a windows partition, plug in the HDD let it do it's thing and then use the "safely disconnect device" feature in windows
    afterwards it simply showed up again
    the cause of this issue lies with connecting to DLNA-compliant devices (eg PS3/TV/xbox/...) and unsafely disconnecting them

  • Western Digital My Book Studio II external hard drive won't mount on Mountain Lion

    I have the Western Digital My Book Studio II external hard drive.  It was working fine.  After upgrading to Mountain Lion, the disk does not mount.  I can't find any help on the Western Digital site.  Has anyone else run into this?  Is there a solution?
    Immediately, I'm more concerned about getting the data off this drive than getting it to work.  If I take it to an Apple Store with another external drive, could they transfer the data to it for me?

    Also, check the Western Digital website for software updates. They have made numerous updates recently.

  • Western Digital External Drive and a VERY slow computer. Is my HD failing?

    Hello, thank you for looking at my question.
    First off, I am NOT very tech-savvy, but I'm willing to research and learn, I'm just afraid to make a mistake and blow up my computer.
    I have had my Macbook for 2 years. I have not backed up my hard drive during that time. Bad, I know.
    Recently I've noticed my Mac getting slow with the "spinning beach ball" showing up more often and everything getting slower. Usually a reboot will help. Yesterday, for the first time, the reboot took about 8-10 minutes! I figured that wasn't a good sign, so I headed down and picked up an external hard drive (Western Digital Essential model, 1TB) and figured I'd back everything up. I formatted the drive according to the Mac partition model (tech support from WD helped over the phone) and got it going. From 1530 to 0800 this morning, of 52 GB it had only backed up 15.3 GB. The fan was running at high speed the entire afternoon and night. That's about one GB per hour. Is that normal?? Then, it froze and wouldn't respond, or back up at all. Just nothing. I held the power button down and restarted it.
    At this point, I am concerned that perhaps the hard drive is failing (hence the speed and fan issues) and that maybe I should be taking it in to a repair shop (we don't live anywhere near an Apple store)
    Do you think this may be the case? Is there any way to back up my hard drive faster - before it dies? I have two years worth of photos and papers, etc on there, music and such and it would be a tremendous loss if it all crashed.

    As slow as that backup was, anything else will be nearly as bad.
    There are four common causes of this:
    Your startup drive is nearly full (less than a couple of GBs of free space). If that's the case, find something big you can "archive" to CD/DVD or copy to the external HD and delete.
    The drive is failing.
    Corrupted directores, etc., in the file system
    One or more "runaway" processes, usually from incompletely-installed or partially-deleted apps
    |
    It's a toss-up; try to diagnose what's wrong, or try to get a backup.
    The fastest way to back up, with the least "thrashing" of your hard drive, would be to start up from your Leopard Install disc and use the Restore tab to make a copy of your internal HD on the external.
    That will copy any file system problems "as is," but if your internal HD is beginning to fail, at least you'll have a full copy of the data (corrupted or not) on the external HD.
    Check this to be sure your WD drive will boot your Mac: http://wdc.custhelp.com/cgi-bin/wdc.cfg/php/enduser/stdadp.php?pfaqid=1787 If not, do all the steps below except #4.
    Here's what I'd recommend:
    1. Start up from your Install disc, per the yellow box in #1 of [Formatting, Partitioning, Verifying, and Repairing Disks|http://web.me.com/pondini/AppleTips/DU.html]
    2. Reformat the external HD, with a single partition, per the blue box there. You'll want the +Mac OS Extended (Journaled)+ Format and either the GUID or +Apple Partition Map+ *Partition Map Scheme* as detailed there.
    3. Use the Restore tab to copy your internal HD (almost certainly named +Macintosh HD)+ to the external HD, per #7 in the link above. Note that will copy the name of the internal HD to the external.
    4. When that's done, quit Disk Utility, then select +Startup Disk+ from the Utilities menu in the menubar (per the yellow box above). Select the external HD and start up from it.
    |
    The copy may take a very long time. There will be a progress bar, but they're notoriously inaccurate under the best of circumstances. If it completes, and you can start up from the external, post back and we'll see if we can find the problem, and either fix it or confirm that you need to take it to Apple.

  • Unable to mount Western Digital Hard Drive after upgrade to 10.6.4

    I have tried to search for a solution to my problem, but have not found anything that seems to help. So hopefully someone here can provide some guideance.
    I have a Western Digital 1TB My Book that I have been using primarily for backing up photos. The drive is formatted as FAT-32 so I can work with it from my Windows XP laptop too if I need to (although my Windows laptop mostly collects dust since getting the Macbook). I have been using the feature in Adobe Lightroom to automatically backup each photo to the My Book when it is being loaded into Lightroom. I also backup the Lightroom catalogs to the My Book.
    Occassionaly I would get the "beach ball of death", but not always related to being in Lightroom at the time. I recently had a beach ball incident. After a restart and using Disk Utility on the Macbook's HD, I decided to check for any updates. At this time I ended up upgrading from 10.6.3 to 10.6.4. After doing the upgrade, I can see the drive in Disk Utility, but the "My Book" volume is greyed out. Running "Repair Disk" has no effect. The "Repair Disk Permissions" buttons are greyed out. I cannot get the My Book volume to mount to be able to use the drive. If I plug the drive into my Windows XP laptop, Windows can work with it just fine. I ran the windows check disk program, which took 24 hours on 1TB, and it did not find anything. Plug back into my Macbook, and it still cannot mount the My Book volume.
    I also tried to plug in a Western Digital My Passport portable 400GB drive which is powered by the USB and does not require a separate power supply cord. It has the same issue where the "My Passport" volume cannot be mounted.
    Does anyone have any ideas on how to get the Macbook to mount the drive again? NOTE: I'll probably not be able to try any suggestions or respond until Monday, but if there are multiple suggestions queued up over the weekend it will give me a good starting point when I can get back to this on Monday.
    Thanks,
    Jim

    The Combo Update worked. But I need to know why.
    Although I have no proof or authoritative source that confirms this, using the Combo seems to account for anything missed by or changed since earlier updates.
    This originally started after check for updates, and the 10.6.4 update is when the problem started. What is different about the Combo Update, ...
    Pragmatically, the difference is that it just works for me. Mathematically:

    If you have skipped some updates, your Mac's Software Update... (SU) will suggest Combo.
    Someone else (Thanks, Defcom! ) told me about Combos years ago while I was still running 10.3.x.
    BTW, many users never use or seem to need the Combo. 
    You seem to be an experienced user. If you have been using Macs trouble-free for a long time without updating via the Combos, you may decide not to bother with the Combo except in specific cases where you have a problem that isn't corrected by other fixes.
    Is there somewhere on the website I need to check regularly in addition to the normal updates?
    You can search Support Downloads for the latest Combo Updates any time.
      http://support.apple.com/downloads/
    You can decide when to search any way you choose, but here is my process:
    • I set my Macs' SU Preferences to Check for updates: "Daily."
    • I do NOT enable "Download updates automatically."
    • When SU notifies me that a Mac OS update is available, I quit SU without installing anything.
    • Then I repair permissions, download and install the Combo, and repair permissions again.
    • I then run SU again to install any other updates that are available on the same date.

  • Macbook Pro Harddrive Upgrade Western Digital Scorpio Blue WD10TPVT

    I recently purchased a Western Digital Scorpio Blue 1TB hard drive (WD10TPVT) in order to replace the 500GB hard drive in my Unibody Macbook Pro 15" running Mac OS X 10.6.4.
    After swapping the hard drives I wanted to install Snow Leopard from the scratch on the empty hard drive. I partitioned the hard drive and started the install, but after about 30 min the computer seems to freeze. I tried several times, and each time the behavior is similar. After swapping the hard drives again (back to the old hard drive) I connected the WD10TPVT via an external USB enclosure, and now it works fine - over an extended period of time. So I'm fairly sure the drive itself is working properly.
    I did some research, and it seems that people had similar issues with this drive (e.g. a thread in this forum titled "WD 1TB WD10TPVT in Late 2009 15" Unibody Macbook Pro - NEED HELP!" from April 15). It seems to me that this issue is old but still unresolved, and I wonder if there are any new developments concerning this problem. Is there a "generic" solution?
    Another question: the WD10TPVT has 4 additional pins next to the ribbon cable connector. I didn't find any documentation on this, but I assume that these are jumper pins. I found some information that certain jumper configurations will/will not work in the Macbook Pro, but no details on this. What jumper settings do I need to get the WD10TPVT running in my Macbook Pro?
    Thanks a lot!

    There are known issues with replacement HD's on 2009 MBP (and, posibly other models too).
    According to Apple support, it is due to acceleration sensor, which in MBP requires HD to have custom firmware.
    There was even a fix to solve this issue (which I cannot find now, and it actually didn't solve much).
    So far, the best "fix" seems to be to install HD with Apple firmware (works 100%). There are reports that certain drives without acceleration sensor are working properly too, a bit expensive to try, though.
    Still a mystery why Apple does not clearly warn about this issue.
