The alias "Harddisk" can't be opened because the original item can't be fou

Hello all,
I have a very scary problem. My external 1.5 Tb Toshiba does not connect anymore. I used to have it connect to my MacBookPro through the Airport Extreme USB connection. Then I wanted to delete a folder, earlier today, and ever since, the harddisk will not mount correctly. That is, every second or third time I click on the alias (in the left area of the Finder Window), it will open and show me the files. I also successfully managed to delete some other files and folders. But, the folder in question caused Finder to start relaunching again and again and again. The only solution was to force the computer to restart, as the Relaunching Finder through CMT-CTRL-ESC didn't bring anything.
I then disconnected the Toshiba from the Airport Extreme, and connected it directly to my MBP. The computer understands that the harddrive is connected, the harddrive sounds and behaves completely normally, and Disk Utility claims everything is okay. Data Rescue 3 claims I deleted some folder in the year 2076, on this very date, 8th May (which in 2076 is a Friday, apparently). I don't know if that has something to do with it?
But the MBP won't let me access the harddrive. I click on the alias to the left (or double-click on the disc icon on my Desktop) and the message in the subject above will appear: The alias 'Airdisk' can't be opened because the original item can't be found".
If I choose to Delete Alias, the following message appears: The Item "Airdisk" can't be moved to the Trash because it can't be deleted.
I I choose to Fix Alias, the standard window in which I can find the normal path appears, causing a loop, since I will get the same message when I click on the disc icon again...
Clicking OK doesn't bring anything. Nothing opens, and I am in the path I was when I started the clicking.
Spotlight works wonderfully. I can search for data on my Toshiba, Spotlight will find it, but there is no link in the bottom part of the window. I can't even Open Enclosing Folder, through right-clicking on any resulting file in Spotlight.
But the Harddrive is well and active.
Does anyone please, please have any idea what I can do to make it behave normally again. And not least how to get rid of that folder.
Please don't tell me I have to reformat it...please?

Thanks for the reply.
I did what you said and can confirm that there is a link to the hard drive under /Volumes/. However, where the links to my two partitions will take me directly to the partitions (Apple and Bootcamp), the Toshiba one will only show a Preview stating the Size of the disk (which incidentally, it states as being the size occupied.
I tried deleting this Alias, but do not have the permission: "The operation can't be completed because you don't have permission to access some of the items".
So I went back to Computer, got Info on the Toshiba and tried changing the Sharing & Permissions. Currently I have custom access:
admin: Read & Write
system: Read & Write
Erik (Me): Read & Write
everyone: Read only
I used to also have (I deleted it):
wheel: Read & Write
I also made Erik (Me) the owner of the disk. I also tried ticking and unticking "ignore ownership on this volume".
On my internal harddrive, Get Info states that I can "read and write". Nothing about Custom Access.
In Disk Utility, when selecting my Airdisk (the only partition under 'Toshiba', there are apparently No owners enabled, and I am not allowed to verify or repair permissions under the First Aid tab.
I notice this, because my internal (Apple partition) does have Owners Enabled and I am allowed to Verify and Repair disk permissions.
Any ideas?
I can unmount it and mount it, but still no difference.

  • Please help! The alias can't be opened because the original item can't be found. Portable Hard Drive, Macbook, OS 10.7

    Hi folks,
    Desperate for some help!
    I have a very cluttered, slow Macbook Pro running 10.7.5. Bought a 2TB WD My Passport for Mac (2TB) with the intention of transferring my many, many files and folders over to it, to increase my memory and boost the performance of my Macbook. (Also handy to have files on the go).sktop
    I transferred everything (all files off desktop, documents, photos etc) using drag and drop.
    Then I trashed all the files, but did NOT empty Trash because I wanted to check the process had worked
    Now, when I plug in my hard drive, and open it up, all my files and folders are there, but with little arrows on the bottom left of the file/folder. When I go to open any one of them, I get this message:
    "The alias “X” can’t be opened because the original item can’t be found."
    I don't know what to do. Is this because of the way I dragged and dropped the files? I'm guessing so. Or is it because I still have the items in my Trash? (I'm obviously petrified of emptying the Trash now though) Is it because of my OS?
    Apologies, I'm a novice to this (hence why my 4 year old mbp is running so slowly; it's got 4 year's worth of work on it, and now I obviously don't even know how to transfer files properly to an external HD) but I'd really be ever so grateful for your help. I just want to successfully back up my files to this HD so my mpb runs faster. I'm now terrified I've corrupted my files. I don't even understand what an Alias is.
    Would love to hear from you! I'm totally new to these forums so hope I've posted right! Thanks!

    It sounds like what got created on your external is a collection of aliases which point to the original files and folders but aren't actually copies of the files and folders themselves. The original items have been moved to the trash so even if they could be found, they couldn't be opened. As a test, pick a file (not a folder) on the external that should be large and see what size it actually is (Get Info). Aliases are smaller so you can tell the difference apart from that little arrow (the Get Info box will also identify the file as an alias). Dragging the files to the external should have automatically created copies rather than aliases unless you held down the Command and Option keys while dragging.
    In any case, you were wise not to empty the trash; to be safe get those important files back out of the Trash so you can start over. But this time, try moving a few at a time and let us know what happens.

  • The alias "Lacie2" can't be opened because the original item can't be found

    A very strange problem just developed. I have a Time Capsule with two external drives attached to it (they are actually two drives in a single enclosure) via USB. When I navigate to the drives, an alias is placed on the desktop. When I click on the alias, I get the message, "The alias “Lacie2” can’t be opened because the original item can’t be found." (I get the same message for the other drive, "Lacie1"). Now, here's the kicker: when I navigate through to the drives in a Finder window, everything is fine! I can access the drives and all contents. I do NOT get this same problem when I navigate to the Time Capsule itself, i.e., the alias placed on my desktop to the TC works fine when clicked. One more bit of information, the enclosure containing the two apparently misbehaving drives accidentally came unplugged a few days ago, so the drives spun down without being unmounted, etc. However, I don't use the drives every day, so I am not even sure they were mounted at the time. Also, I can't be certain this current problem started IMMEDIATELY thereafter, again because I don't access the drives every day and just can't remember.
    I have opened "Volumes" and cleaned out all the ghost/phantom drives in there, and it did not help (none of the ghosts referenced either of these drives). In case it makes a difference, I am booting the 64-bit kernel. Any ideas?

    I checked /Volumes again, but no ghost drives. When I select one of the aliases on the desktop and enter command+i, here is what the "server" field says in the popup:
    afp://Time Capsule Kay.afpovertcp.tcp.local/Lacie2
    When I open a finder window and navigate to the drive, here is the path to one of the folders there:
    afp://Time Capsule Kay.afpovertcp.tcp.local/Lacie2/Steve
    I don't know if this makes any difference, but when I mount that same drive on my G4 running OS X 10.4, the path is different:
    afp://Time-Capsule-Kay.local./Lacie2
    The G4 has always been plugged into the TC that the drives in question are also plugged into. Until recently, the MacBook Pro that is giving me the problems connected to my network via AirPort. It is now connected via Ethernet, plugged into an AirPort Extreme which the TC feeds off of via Ethernet as well. Perhaps that's why the paths are different.

  • "The alias can't be opened because the original item can't be found"

    Hello,
    I use many alias folders to take advantage of copy.com applications feature which allows you to have aliases in the "Copy" folder (i.e. Dropbox doesn't) and sync them with the cloud. It's an easy backup solution.
    My problem is that very often most of these aliases stop working. Double clicking pops out the message "The alias can't be opened because the original item cant' be found" even if the original file/files have never been moved neither renamend.
    Googling and searching in the forum suggested to check and fix premissions with disk utility. I did it but nothing was solved. I use to do this every week since I noticed that Disk Utility always find something corrupted.
    What can I do?
    I have a mbp mid 2009 with ML 10.8.5.
    I don't know if the hdd is going to fail (since utility disk always find something wrong), is there someway to test it?
    Thanks for your help,
    Andrea

    As an experiment, pick some sample Aliases that seem to constantly break, and replace them with symbolic links (a Unix feature).
    Either do this via an Applications -> Utilities -> Terminal session
    ln -s "drag_and_drop_file_or_folder_from_finder_here"  "drag_and_drop_destination_folder_here"
    Or get a GUI utility to make symlinks
    <https://www.macupdate.com/find/mac/symlink>
    Now see if the symlinks work and do not get corrupted.
    If Symlinks work long term, then replace the rest of the Aliases you are using for copy.com with symlinks.

  • The alias can't be opened because the original item can't be found - After USB Flash Drive transfer

    I've seen a couple of threads about this message, but none dealing with my simple issue:
    I get this message: "The alias can't be opened because the original item can't be found" -- AFTER TRANSFERRING THE FILE IN QUESTION VIA FLASH DRIVE.
    I thought, maybe the "original item" hadn't been completely copied from the drive, so I tried opening the file again this time with the drive still plugged into the laptop--but again, the message came up and I couldn't open it.
    What's the deal?
    The files I'm transferring:
    a 1.2GB MKV file of a movie I downloaded, which I had no trouble viewing on my desktop
    a 105MB application
    (btw, the application is called "VLC", which is a file playing app that works on my desktop, and I want it on my laptop so that I can play movie files like .mkv, which is the other file I'm transferring...but that doesn't make any difference, I think. No, I can't just download the movie and the app right onto the laptop...I don't have wifi right now...='[...)

    I had been dragging straight from the desktop into the USB window. Eventually, I opened up finder and went to Desktop there, and when I dragged the files from there into the USB window, it worked. Now it took a while to move the files into the USB, which was a sign that they were actually being moved.

  • Data folder can not be opened in finding " AirPort Time Capsule " The operation can not be completed because the original item for " data" does not exist .

    Hi
    I have a " AirPort Time Capsule " (firmware 7.7.3) When I try to open the data folder in "finder". Then I got the message  " The operation can not be completed because the original item for " data" does not exist". I have a lot of data and I can understand why I get this message?

    Get a USB drive of 2TB or more.. assuming your TC is 2TB. Either preformatted Mac or plug into your Mac and format it standard Mac OS Extended Journaled in disk utility.
    Do a full archive of the TC. You do this using airport utility. Do not click the erase disk.. I marked in green.. just the archive.. that is to backup the internal disk to the USB disk. It is not fast.. take it that the process will go at around 40-50GB/hr.
    Once you complete the archive .. it is a direct image of the data on your TC.. you can then plug it into your computer directly.. and then try and open the files you lost.. if you cannot open them.. open disk utility and fix the permissions.
    http://osxdaily.com/2015/01/13/repair-disk-permissions-mac-os-x/
    Or try the methods apple recommends..
    OS X Yosemite: Set permissions for items on your Mac
    It is possible to fix things on the USB drive because it is locally mounted.. but you cannot fix it on TC which is network drive.

  • I can't connect to the drive on my airport time machine and am receiving the message: "AirPort Time Capsule" can't be opened because the original item can't be found.

    Time capsule has been working perfectly for months.
    Suddenly I can't connect to the drive on my airport time capsule and am receiving the message: “AirPort Time Capsule” can’t be opened because the original item can’t be found.
    Time machine appears to be still backing up (last backup within the last hour), but drive is not visible and I have files stored on it.
    I have tried rebooting everything in order as suggested for other issues, anyone got any ideas how to see the drive again??

    What OS are you running??
    It is very typical Yosemite issue.
    1. In airport utility does the TC show up.. if so click it.. and see the summary page which will include its IP address. That is what you are after.
    From my screenshot you can see the TC address is 192.168.2.57
    It might well show up briefly after a reboot or in ipad / iphone version utility. Yosemite is hopeless. The airport utility hardly works.
    2. In Finder use Go, Connect to server.
    Type in SMB://192.168.2.57 (replace with IP you discover).
    If it is possible it will request a password.. type that in and DO NOT FORGET.. to store it in your keychain.
    This will work until the TC changes IP which won't happen if it is main router.. but will happen if it is bridged.. so you need to tell me the whole network setup.
    Mavericks is nearly as bad and the above instructions should be universal except I would use AFP instead of SMB. Apparently Yosemite is now totally Windows oriented.

  • Time Capsule / Leopard 10.5.8 / Time Machine / Disk can't be opened because the original item can't be found / OSStatus error -6602

    Hi,
    I'm facing a big issue with Time Machine on my Mac Book running Leopard 10.5.8 (build 9L31a) and my Time Capsule (firmware 7.6.1 (76100.4)).
    I have searched a lot (during 3 days !!) to find a solution but no luck !
    I have the same syntoms as described by LUNY in this thread: https://discussions.apple.com/message/9364556#9364556
    To quickly summarize:
    My MacBook was configured to use my Time Capsule as backup disk. Everything went fine during 2 years and then one day I suddently got problems with time machine !
    Time Machine was unable to access my Time Capsule. Moreover it was drastically slowing down my MacBook !
    So:
    1. I stopped Time Machine and tried to change the backup disk: every time I chose my Time Capsule Disk, I got a OSStatus error -6602
    2. Then, I tried to access my Time Capsule from the Finder -> slow and then got this message 'Disk can't be opened because the original item can't be found'
    3. I searched in the logs for the specific reason and I found:
       - system.log (/var/log) :
          myMacBook kernel[0]: disk0s2: I/O error.
          myMacBook /System/Library/CoreServices/Finder.app/Contents/MacOS/Finder[198]: NetworkNode::handleMountCallBack returned -6602 (the same error)
          myMacBook ReportCrash[358]: Saved crashreport to /Library/Logs/CrashReporter/kextload_2012-12-30-112946_myMacBook.crash using uid: 0 gid: 0, euid: 0 egid: 0
       - In CrashReporter (/Library/Logs/CrashReporter/): i see the problem coming from kextload with this exception:
           Exception Type:  EXC_BAD_ACCESS (SIGBUS)
           Exception Codes: 0x000000000000000a, 0x000000000122d000
    4. I tried to mount the time capsule disk with Terminal (AFP protocol):
       > mount -t afp afp://admin:[email protected]/Data /Volumes/termAFPData/
       result -> mount_afp: AFPMountURL returned error 19, errno is 19
    These errors (6602 and 19) are neither documented anywhere nor associated to a clear description of the problem. The only thing I have found is that errno 19 is an IO error -> http://www.opensource.apple.com/source/CarbonHeaders/CarbonHeaders-18.1/MacError s.h
    On the other hand, and this is the really weird part of the issue, my time capsule disk works well when I mount it with SMB protocol !!! (Or when I access it with a Windows XP machine).
    So, the workaround is: mount -t smbfs //admin:[email protected]/Data /Volumes/termSMBData/
    Or, in Finder -> Connect to server and there use the URL: smb://xxx.xxx.xxx.xxx/Data
    Not sure what is going on ... but I pretty sure that's a bug and not a hardware problem.
    Is there someone who has already found a solution for this kind of behaviour ?
    It would avoid me a lot of headaches and improve the support for this kind of problem.
    Thanks !!!

    When you say: "I would though go back to 7.5.2 firmware." Do you mean a reset to factory default ?
    Greetz
    NO, your time capsule is running 7.6.1 but it is built with AFP following increased security for LION.. that is not required or available in Leopard.. so there is no point.. it is also not as stable on the older hardware.. at least in my experience.. I have repaired about 200 of the suckers so I do see a few.
    When you select firmware update in the airport utility.. hold the option key.. all valid firmware versions for your TC then show up.. not only upgrades.. select 7.5.2 and upgrade to that.
    Do a factory reset when you do it is a good idea though.. start off again.
    And do reset of TM.. A4 in pondini.
    See if it helps.
    Oh, the TC will continually complain about needing a firmware update.. turn off automatic checking of updates.. it will still annoy you for fun every few weeks but that is better than daily.

  • I recently tried to burn some photos to a disc.  It did not work, but then I ended up with a .fpbf folder on my desktop.  Can't trash it, and when trying to burn again, I get this "... can't be burned because the original items can't be found". Help???

    I recently tried to burn some photos on a CD. For some reason, It did not work.  Now I have a .fpbf folder on my desktop. I can't seem to get rid of it.  I tried dragging it to the trash, but then I get a box asking my to type my password it, so Finder can make the changes.  Doing so, does nothing at all.  And when I try to burn another CD from the same .fpbf file, I get a the following message: "There are 35 items that can’t be burned because the original items can’t be found. Skip the items and continue burning?".   When I skip and continue burning, nothing shows up on the CD.  In the meantime, the .fpbf folder is still in my desktop.  I tried changing the aliases on each pic, but it still doesn't work.  Any ideas of how I can remove this folder from my desktop?
    Thank you.

    Beavis2084,
    Thank you for your detailed explanation but something is seriously wrong with my computer. Although the method you have described is very similar to the one I tried in step 2 from my second post, I have since "done things" which may have complicated matters—or suggests that my computer has a more serious problem.
    Here's what I did:
    1). Installed Onyx and discovered that I had a .plist file (com.apple.iphotomosaic.plist) that was causing a Syntax error: "Conversion of data failed. The file is not UTF-8, or in the encoding specified in XML header, if XML." After doing some research online, I was given the understanding that downloading the iLife update 9.0.3 (I installed the more recent version, 9.0.4) would solve this problem because it would also fix some system issues. So, I downloaded it...and when it didn't solve the problem, I decided to just deleted that .plist file.
    2). I read your knew post and decided to follow your directions, even though I realized they were basically the same steps I followed in the 2nd method I mentioned earlier. I say "basically" because, for some reason, after inserting a blank disc, my computer does not open the disc in the Finder. Instead, it places the blank disc's image on the Desktop, even though the Finder's Preferences and the System's Preferences are set to have it open in the Finder—nothing should be on my Desktop! (Note: When transferring the items (all folders) I want to burn to the blank disc, I did not use the Option-Click-Drag method as before, I used the Click-Drag method, which created the curved arrow in the lower left corner of each item.)
    Now, for the result of "method 2," the method we basically have in common, the computer goes through the burn stage but, in the verify stage, tells me that it is unable to verify the disk, suggests that my DVD may be unreliable and that I should try another disc, and then tells me about some "fork" (?) error (-43).
    I don't know what to do anymore...

  • The operation can't be completed because the original item cannot be found.

    Hi all.
    I've been having this problem for a while. I have a file server on a windows xp system with multiple drives attached to that pc (internal and external).
    When I try mounting one of them from the finder I get the message :
    +*The operation can’t be completed because the original item for “Movies” can’t be found.*+
    Other drives on the pc mount just fine and actually the problematic one used to mount fine and then suddenly it seems that the mac lost the path to the disk and can no longer find it.
    I tried reformating the drive, changing the drive letter, and naming. It worked for a while then the drive got lost again
    Its a WD drive formatted to ntfs (Identical configs and brand to all the other working drives) Its not a drive defect either. Its happened more than once.
    I'm quite knowledgable when it comes to computers but this has been a dead end for me and I'm sure for others as well.
    Please Help

    I was about to post exactly this question. I have suddenly lost access to the folder on my shared network drive although the drive itself is still visible. I get the above error message when trying to open folders within. I have tried connecting through various routes such as Go - Connect to server ... but its the same.
    A discussion thread elsewhere talked about deleting multiple share point entries ... over my head though.
    Hope someone out there knows the answer - and how to explain it in plain english

  • The operation can't be completed because the original item ".." can't be found.  Need a fix!

    Ok.  This is my first and hopefully only discussion ever!  Thanks in advance for all the help.
    I had set up my network and this was all working fine for months.  Time Machine did proper back ups and I could store files on the drive as well over the network.  Not sure how, or exactly when this error began.  It may have had something to do with the upgrade to Mavericks.
    But I can see the drive when I open Finder (which I have named Airport) can then access the directories but will not load any of the files.  If the Finder window is closed and I try to access the external drive again via the network, I am prompted with.."The operation can't be completed because the original item ".(Airport)." can't be found. Also of note...there is no "eject" option beside the name of the drive.
    I have found only one solution that was dated in 2008 where someone was deleting volumes from their machine and the instructions were not quite clear, so I'm hoping for some new insight on this issue.  Honestly, I just didn't understand how to do what he said...several have asked him to elaborate but no further explanations and all other links are now dead.  It seems this is a common issue.  I'm aware many people will read this and want to say..."i Have this problem too, when im doing something with windows and other computers..."  There are many solutions for these situations that I have found....but no recent ones for those with ONLY one drive and an airport extreme running only Apple computers.  So guys, lets try to keep this thread for one topic only.  Hopefully a quick and helpful thread with a few replies and some step by step directions to solve everyones toubles.
    I even had my router replaced and still the same issue.  Also, the hard drive works perfectly when hardwired to my computer.  So the issue must lay within the settings of my MacBook Pro, OS X 10.9.1.  If you feel I should provide any other information I would be happy to do so!

    Lexvo,
    Thanks for the input.  I had to look up what SMB stood for, server message block?  So I'm assuming this is not something I'm using.
    Also, this is not a "sometimes" problem.  This is a consistent and reproducible issue. 
    As far as an update...I dont see an OS update fixing my issue unless something is overwritten, but maybe not. 
    I think a good point to consider and open to discussion is why does logging in as a root user solve the issue?  What can be done or manipulated to allow functionality with my regular login info versus a root user?

    I have a user on an iMac 10.6 connected to our domain.  She uses Outlook web access for email on our exchange server.  Last week she received the following message which is randomly preventing her from sending emails.  She claims no attachment was involved in the original email when this all started.  I have not been able to look at her account as she is out of the office but maybe someone else dealt with this issue.  I realize this may not be Mac related but thought I'd give it a try.  She did say it occurred once over two days while working on a PC but it continued over the past weekend.
    If an internal user tries to send a message with infected attachment using Outlook Web Access, it may report the following error message: The action could not be completed because of a conflict with the original item. The conflict may have occurred when an existing item was updated on another computer or device. Open the item again and try making your changes. If the problem continues, contact technical support for your organization.
    This is because F-Secure Anti-Virus for Microsoft Exchange has detected a virus in the attachment. If the user tries to send the message again, the message will be sent but without the attachment. At the same time a blank message with an attachment named "Attachment_information.txt" will remain in the user's Drafts folder. The "Attachment_information.txt" will contain information about the virus detected in the message.

    PS - have found other posts indicating that clips smaller than 2s or sometimes 5s, or "short files" can cause this. Modern style editing often uses short takes ! Good grief I cannot believe Apple. Well I deleted a half a dozen short sections and can export, but now of course the video is a ruined piiece of junk and I need to re-do the whole thing, the sound etc. which is basically taking as much time as the original. And each time I re-do it I risk again this lovely error -50 and again trying to figure out what thing bugs it via trial and error instead of a REASONABLE ERROR MESSAGE POINTING TO THE CLIP IT CAN'T PROCESS. What a mess. I HATE this iMovie application - full of BUGS BUGS BUGS which Apple will not fix obviously, since I had this product for a few years and see just hundreds of hits on Google about this error with disappointed users. Such junk I cannot believe I paid money for it and Apple does not support it with fixes !!!
    If anyone knows of a GOOD reasonably priced video editing program NOT from APPLE I am still looking for suggestions. I want to do more video in future, but obviously NOT with iMovie !!!
