External HD won't mount, lots of errors

I bought a 250GB Maxtor internal harddrive and installed it inside a no-name external enclosure. It's connected through USB2. When I connect it, I get a pop-up that says "disk not recognized" with options to initialize, ignore, or eject. I went into Disk Utility and partitioned the disk...still won't mount. I then reinstalled the 10.4.3 combo updater...still no luck. When I try to repair the disk through Disk Utilities it says:
"Verify and Repair disk “disk1s3”
Volume check failed.
Error: The underlying task reported failure on exit
1 HFS volume checked
1 volume could not be repaired because of an error
What can I do to get this hard drive to mount and work?

Put it into a FireWire enclosure. USB is basically useless; normally unbootable. You can get a decent FW/USB combo enclosure for under $50. I like this one (I have two): http://www.pcmicrostore.com/PartDetail.aspx?q=p:10500933 ($38 US + S&H).

  • 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.

    When I tried to run Migration Assistant, I just get the spinning search circle and none of the drives come up, just endless searching.
    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"

  • Thunderbolt external SSD won't mount

    I'm using the Elgato Thunderbolt SSD as an external hard disk with my 2013 MBP. Since I'm also using a Thunderbolt display, I usually daisy-chain the disk to the display.
    Recently I disconnected the Thunderbolt display from my computer without unmounting the external SSD. Since this also disconnected the disk, I got the usual ticking-off ("You should eject a disk before disconnecting it").
    However... since then, the external disk won't mount. It doesn't show up on the desktop or in Disk Utility, though it DOES show up ("Thunderbolt SSD") in System Information.
    Because the SSD gets warm when it's in use, I think it's still working. I just can't access it.
    Can anyone help?

    Is the Apple Thunderbolt Display at the END of the daisy-chain? That's where it should be - all other TB devices should be connected first, with the Display at the end of the chain.
    As to why you're having a problem getting the TB SSD to work, I'm stumped. It seems as if you've done everything that I would try to do to get everything working... and I'm assuming that you have powered down and unplugged the Display and all other devices for 15 minutes or so?
    Just make sure that the Display is at the end of the TB chain - that's really the only advice that I can offer.

  • External HD won't mount on PB

    External HD won't mount on PB but, will on iBook, G5 iMac, MBP, and Mirror Door G4. I have a USB 2 HD that will mount on everything but 15" Aluminum PowerBook. I even tried updating the IOUSBFamily.kext but no luck that just made my camera to start working with my PB. When I plug in my HD the LED just blinks back and forth orange and green instead of Blinking orange and turning a solid green when connected.
    Any sugestions?

    In reply to arnie: Good tips!
    I'll just add - booting holding "AppleOption+OF" boots into open firmware. I've never booted into this mode (on purpose...) but it seems to be (correct me if I'm wrong) a unix interface to OS X. Just make sure to type the commands EXACTLY. Unix is much pickier than OS X.
    I've heard problems like this before - usually with those little bus-powered HDDs and Powerbooks. It's something to do with the amount of power the Powerbook puts out, although it should be the standard 500 mA that the USB 2 specs require. This can happen with firewire, however. If there's a power cord, use it.
    You might try plugging the drive into a self-powered USB 2 Hub - one with a cord that plugs into an AC wall socket, then connect it to the Powerbook. If the Powerbook recognizes the drive, then it probably needs extra power.
    Good luck

  • LaCie external drive won't mount on iMAC

    Hi,
    My external LaCie external drive won't mount on my iMAC running 10.6.8 but will mount and show up on my PC as working fine, however I am not able to read the information on it as it was formatted for my iMAC. Therefore it leads me to believe this is a software issue.
    I have reason to believe someone had changed the permissions and prevented the mounting of this external drive (which belongs to me)  so that the contents won't be found on my iMAC.
    How to resolve this issue?
    Thanks in advance,
    Cait

    Cait,
    Please try a SMC reset, it may take 2-3 attempts for it to work. Look over the instructions below carefully.
    SMC RESET
    Shut down the computer.
    Unplug the computer's power cord and all peripherals.
    Press and hold the power button for 5 seconds.
    Release the power button.
    Attach the computers power cable.
    Press the power button to turn on the computer.
    PRAM RESET
    Shut down the computer.
    Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously in step 4.
    Turn on the computer.
    Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.
    Hold the keys down until the computer restarts and you hear the startup sound for the second time.
    Release the keys.

  • External disc won't mount in Leopard, but will in Snow Leopard

    I have a 5-yr-old G5 networked to a new iMac. I have had a 1-TB external HD attached via Firewire 400 to the G5 for about a year. Yesterday it didn't show up on the G5 desktop. I went to this forum, searched under "disc won't mount", got some ideas, ran DiskWarrior and Disk Utility...but nothing worked. They all said the disc was fine, directories rebuilt, etc., but it wouldn't mount. This AM it occurred to me that I had the correct cable, so I tried plugging it into the iMac instead. It worked. The data is safe, the disc shows up, everything seems to be OK, but it won't mount to the G5. Why would that happen, and how can I mount it to the G5? And how likely is the disc to remain accessible?

    May I hop onto your thread as I have a similar problem.
    I have a 5 year old G5 PMac with 10.5 onto which I have daisy chained two UltraMax 1TB firewire 800 drives. For the last 5 years I have been able, even with out sharing enabled, to connect to the G5 from a G4 Graphite with 10.4, a G4 Powerbook with 10.5 and now a MbP with 10.6.
    After completing the login dialogue in the past from any other mac it would give me a list of the G5, it's Hard disk, user directories and the two Firewire Drives. On selecting them the drive would mount onto the desktop as a network drive. This went well until monday when it became temperamental in the morning and after a few restarts and one successful mount it has not shown up since. If I come to the G5 via the Go > Connect to Server I get a dialogue "Could Not connect to the server because the name or password are incorrect". If I try to connect via the network icon in the side window of the finder window I get a network dialogue log in, I get a list of folders and drives but then when selecting the FH drive get an error message which relates to the alias to the G5 Server requiring deleting or fixing.
    Originally it just connected without any messing but now unless i make the firewire drive a shared drive the process on the other macs cannot see the firewire drive. NOTE - After having made the internal boot HD of the G5 shared, I can now see and mount this drive from the other macs but not the external drive.
    This is causing me to pull my hair out, I have run disk utility, powered down unconnected and reconnected everything .The HD's appear to be working ok from the G5.
    I urgently need to connect the FW drive to my G4 to do some work but it also needs to be connected to the G5, has anyone got a clue why I cant get G4 (or any other mac) to mount G5's external FW drive

  • External drive won't mount. Options?

    Hi everyone. I've used a LaCie 250GB D2 external hard drive for a little over two years with no problems. A few days ago, I bought a Western Digital 500GB drive to serve as my main external drive, so I decided to erase and reformat the LaCie drive, which I had previously partitioned into two volumes, to serve as an archive drive.
    That's where my trouble started.
    I deleted all my files off the drive and then selected Erase in Disk Utility. I checked the option to eight way random write over format the disk for increased security, but that seemed to be taking so long I just quit Disk Utility. I figured since I didn't have any data I was afraid of losing, it wouldn't be a problem.
    The next day I tried to erase it again, but I got an error message that said something about my partition (sorry but I can't recall what the message was; at this point I still didn't think there would be any problem).
    Yesterday night, I tried again to erase and reformat the disk. I selected the option to zero all data because I thought that might solve any hard-to-fix problems. I left Disk Utility running overnight and all day today--about 20 hours in all-- but the progress bar showed no progress. None.
    Now, as of this evening, I can't get the drive to mount at all. When I plug the drive in (and I've tried all three interfaces), the blue activity light starts blinking and I can hear it spin for a little while. It eventually stops spinning but the light keeps blinking.
    I've tried unplugging the drive and plugging it back in. Nothing. I own DiskWarrior, but as far as I can tell there's nothing DiskWarrior can do if the drive won't mount.
    I'm wondering if disconnected the drive while it was running could have caused this problem. I might have done that inadvertently when it was taking so long to format. I figured that might result in loss of data, but I wouldn't think it would render a drive completely non functional.
    I'm guessing the problem is probably a failure of the drive, but the fact that this only cropped up when I tried to reformat it seems suspicious to me.
    If anyone has any suggestions for ways to get the drive to mount or format it, I'd sincerely appreciate hearing them. Thanks.

    Thanks for quick reply. Boy, I really screwed up. I guess I didn't think I could permanently ruin a drive that way. I just assumed as long as the drive could spin and wasn't going bad, you could always reformat it.
    Just so you know, I let my iBook run untouched for literally 20 hours in the zero out erase mode, but the progress bar showed no progress at all, so I think the drive must have already been broken by that point. I was prepared for it to take a day or more, but with no visible progress in 20 hours it would have taken weeks.

  • External disk won't mount after 10.5.7 upgrade

    Hi,
    I know there's problem with Buffalo external HD; mine is Lexcron 3.5'' external case and it won't mount neither. I tried PRAM restart, and if I go to Disk Utility and try to repair, it gives me the following message:
    Verify and Repair volume “Dirty Hary”
    ** /usr/local/bin/ntfsfix has been disabled because of volume corruption issues.
    ** If you still want to try fixing your volume, use /usr/local/bin/ntfsfix from the command line...
    Error: Filesystem verify or repair failed.
    It worked with 10.5.6 and it still works with Win XP (it's NTFS format).
    Is there something that I can do?
    Will this issue be solved in Snow Leopard?
    Thanks in advance for any kind of constructive info (I've already read threads with Buffalo issue, but I didn't find any thread giving a solution).

    Hi V.K.,
    Thanks for your response, can you provide some more details?
    OS X has very limited support for NTFS. you need to repair the drive from windows.
    How do I do that? I mean the disk works normally in Win XP and it worked normally in the previous OS X version. Btw. I've also installed NTFS-3D which allowed to write on the disk and search from spotlight (of course when it was mounted).
    run chkdsk in windows and see if it finds any errors.
    http://support.microsoft.com/kb/315265
    it can also be that the problem is caused by ntfs-3g which is known to have a number of bugs. you can try uninstalling it or plugging in the drive in a mac without ntfs-3g installed.
    there is no "issue" to solve.
    Well if it worked in 10.5.6 and it works in Win XP and it doesn't work in 10.5.7 I am tempted to say 10.5.7 has an issue.
    the fact that you have a problem with one drive on your particular system doesn't mean there is a problem with os x in general. an issue is when all or at least many people have a problem, not one.
    furthermore, NTFS is a proprietary file system of Microsoft with closely guarded secrets about its inner workings which is why it has very limited support on other types of operating systems. apple is under no obligation to provide ANY support for something like that. programs like NTFS-3g are essentially unauthorized hacks.

  • HT1782 External HD won't mount, suggests disk utility to repair, but I can't back it up.

    Hello,
    I'm having some problems with my Western Digital My Passport 1TB.   When I plug it in I receive an error that says "the disk you inserted was not readable".  I've read some suggestions that say to you Repair on Disk Utility, but others that say to back it up first.  Unfortunately the disk won't mount so I can't back it up.  Am I best to unplug it and try it on a new machine?  Or verify? Or repair?
    I'm sure this goes without saying, but the contents are extremely valuable to me.  What is the safest method to retrieve it?
    Thanks very much for your help.

    I would try shutting down, unplug the WD external drive, restart and after getting to my Desktop, plug the WD drive in and see if it's mounted and readable.

  • My dumb external LaCie won't mount.....AAARRRGGHH!!!

    I'm really hoping someone can help me here. I was working on some illustrations and in Manga studio debut, i opened a window to post some work i created into my external harddrive. I mistakenly hit the "eject" symbol that unmounted my hard-drive from my computer. So i said to myself,"No biggie... i'll just shut the drive off, unplug it, wait awhile, replug it, shut it on and it'll mount again.
    nope.
    I shut it off, unplug it, restart the computer. plug it and turn the external harddrive power on... nothing. i wait patiently thinking it'll eventually kick in.
    no kicking.
    i'm a 40 year old man i'm contemplating crying now... because more than 200 gigs of important work is on my drive and i can't access it.
    That and stupid Leopard can't even do the most basic commands.. like accessing my printer. Just get that dumb beachball. Even opening System preferences gives me problems. More beachball.
    I'm looking for help here. Please help.
    How can i shed my computer of the recent upgrade and go back to 10.5.2?
    and Since nothing can be wrong with my LaCie by just unmounting it, what can i do to get it to mount? Just leave it plugged on and powered and pray that the OS recognizes it and hope it mounts?
    I don't have that kind of time.
    If i need to retrieve all that data onto another new external, how much will that cost me?
    I know i'm asking a lot of questions, but i'm desperate here.

    The problem is that it won't mount after it has been unmounted. A friend of mine who's a Mac Repairman told me that it could be a number of things...
    he told me to check if any smells were coming from the drive...
    nope. check.
    If the fan had stopped working... nope. check.
    If it's a problem being caused by the enclosure.... that i'm going to check on.
    I called TekServe in Manhattan and when i get paid, i'm going to see if that's the case.
    But they want 1200.00 for data retrieval in a worse case scenario... and i'm going to shop around for that one. I have a feeling that they corner the market in that area for Mac repair and they probably feel they can charge whatever they want and people will pay.
    1200.00 is another computer. I'd rather do my research before shelling out that kind of dough.
    I had unwittingly unmounted my first external 3 years ago .... it's a Wacom, and it mounted with no problem after literally a minute.
    So i don't know why this LaCie is giving me problems.
    So i'll try changing enclosures and check out reports for the companies with the best all-around reports on their externals before i buy.
    It may not last forever, but i should get better than an external HD's "refusal" to mount once unmounted.
    It just doesn't make sense.
    Besides, i have a feeling that my computer won't register it's existence if it doesn't mount to make itself known.
    Tell me if i'm off.
    BUt i will consider the other programs that you guys have suggested.

  • URGENT External drive won't mount

    URGENT: I have lots of video I need to process this weekend, and I can't even download anything now.
    So I have been using my 2TB external drive for six months without a problem. Yesterday I had it plugged in (I use it as storage for FCP) and I tried to open Final Cut Pro X (it had been open and rendering for hours, I had just closed it for a few minutes). I noticed that none of my events or projects were visible. Checked the Finder and the drive wasn't showing up.
    Disk Utility shows it, but the single partition I have on it will not mount. Same error every time. Tried to repair and verify in DU, but it said everything was "OK" both times. Not helpful. Went to Terminal, and tried to mount there but the same vague error message- SEE BELOW.
    Any idea what changed, and how to fix it? Tried to search in the forums, Google, etc, but no help.

  • Maxtor External Drive Won't Mount!

    Here is my problem.
    We got a Maxtor One Touch III 1 TB external drive. I loaded about 850 GB of media onto it, passed it off to my partner to continue to edit our video project. Everything was running fine on my macbook pro 2.2 core duo. He edited for a day on his macbook 1.83 core duo. Said everything was fine.
    That night he shut the machine down without unmounting the drive. He said the drive kept blinking so he shut it off. In the morning he tried to connect the drive to a g4 tower running 10.3.9. (I never realized he was so tech-vapid). He said the drive wouldn't mount. Then he moved it back to his macbook. Still wouldn't mount. Now it won't mount on my macbook or any machine. He then wonderfully told me he once had the same problem with a G-Drive 500 GB external. Wouldn't mount after switching it to his g4 and back. G-Tech told him the drive was dead so he sent it back. Maxtor told us this drive is dead, but I just think it sounds fishy.
    It is still spinning, but there is no light on. Have tried every different kind of connection and updated drivers, same result. A friend said if it got unintentionally unmounted it might take the OS hours to fix it up because it's a RAID 0, suggested leaving it connected for a few hours and see what happens, but that happened once with my G-RAID and it didn't need time to fix itself. I am stupid for buying a maxtor it seems, but it doesn't change my dilemma.
    Someone help.

    Check the /Volumes/ folder for a broken alias to the disk. The folder is invisible so you need to use the "Go" menu to open it.

  • Re: WD External drive won't mount

    Hi
    I have just experienced this issue today. I have gone through all the threads here and searched various other forums but haven't been able to come up with a solution yet. I might be missing something.
    I'm running a 2011 Mac Book Pro OS 10.9.5 Maverick.
    I have a 1TB My Passport for Mac that's a couple of years old now, it is used for my time machine backups. Using WD Drive Utilities, I can run a smart status scan which passes, the quick drive test Cancels.
    In disk utility it appears on the left but is greyed out. The info that is provided tells me it is: (bare with me I'm using my iPad as my MacBook Pro won't allow me to Ely to this forum, an issue to tackle after this one)
    type: partition
    mount point: not mounted
    owners enabled: no
    journeled: no
    disk utility is the only place I can see the drive appear. I don't Have the ability at the moment to connect the drive to a windows pc. I have also tried using disk utilities repair and erase options with no luck. I have tried using terminal and activity monitor several times as previously mentioned in this thread but again no luck but may have missed understood the directions.
    I would simple reformat the drive but suspect because it's greyed out its why I can't.
    any help or directions would be great?
    thanks for your time and knowledge.

    Read all the threads on this.  I am similar to Phoenix86.  I force quit fsck_hfs a few times when I started the bad drive but that did not prompt anything in finder. Currently I am imaging the drive to see if that gives me access to my files on the external.  Last night I did a restore, but the (brand new) drive it saved to behaves just like the bad one that disk utilities so still can't access the files since that one won't mount either.  I also tried a few things in terminal that someone else suggested, but like this repair:
    fsck_hfs -r /dev/disk2s3
    ** /dev/rdisk2s3 (NO WRITE)
    Can't open /dev/rdisk2s3: Permission denied
    I don't know what to do with this message... 
    I feel so stupid, like the files are right there, but I can't get to them to copy them over.  I can hear the disc spin, and it can eject from disk utility, can't open, not even in volumes directory. 

  • WD External drive won't mount

    Hello everyone! I haven't been here in a while because I just haven't had any Mac issues. Now I do.
    I have a 1 TB WD external HD that won't mount. I connect it via firewire to an Old G4 Sawtooth running OS 10.5.8. My mac sees the drive, it just won't mount. I've also tried to mount it via USB, but again, my system sees the drive, but won't mount it. I inadvertantly disconnected the firewire cable, which I didn't realize for several hours. I reattached the cable, tried to mount it, and nothing. I ran disc repairs, and Disc Utility actually told me the drive was successfully repaired. Again I tried to remount it, but nothing. I repaired permissions, and this didn't work. I've tried different cables, and this doesn't work.
    I don't have another Mac to connect it to, so I don't know if this would work. Here's where things get a little wierd, but interesting. I connected it to my PC laptop, and it mounted. Now, this is a drive that was formatted Mac OS Extended (Journaled) on my G4, so I have to use Mac Drive so my PC will recognize and mount The Drive. So My PC sees The Drive as Mac OS Extended, and mounts it. All files are in tact, and the drive runs normally. This is a music drive and it plays normally on my PC. Meanwhile, if I try connecting it back on My Mac, the name of The Drive randomly changes from 931.5 GB WD to 931.5 GB WD My Media Book. I believe My Media Book is the factory name of The Drive before OS formatting. The Volume name remains the same on my G4 each time I've tried to mount it.
    I do have another identical drive that mounts from all the bus ports on my G4. Any ideas here? Can I get my Drive to begin mounting on my G4 again? Any and all answers are appreciated.

    Terminal List. disk4 is the malfunctioning drive.

    I've read that WD uses crappy chipsets in their external drives. I'm wondering if the chipset is suspect here? Just not sure. I did discover that I can clone the drive from my PC as an exact Mac OS Extended (Journaled) drive, and my Mac doesn't even know the difference. I've also read that I can initialize the drive, and reinsert the drivers, and the drive should function normally. Interesting, huh? Well, let me know what you come up with BDAqua. And again, many, many thanks.
