Netcenter Drive Disconnects When Copying:  Error -36

I recently purchased a 250 GB Western Digital Netcenter Drive for my network. Model Number: WDXE2500JBN
I am able to connect directly to the drive by using either the Network browser in Finder or mapping to the drive directly using "Connect to Server" in Finder with the IP address of the drive, i.e.: smb://10.10.10.10/shared
The drive inconsistently disconnects when copying any amount of data (I am trying to backup my iTunes). After a few minutes of copying I receive the following error:
'The Finder cannot complete the operation because some data in "" could not be read or written. (Error code -36).'
I have tried to reconnect, reboot, restart, the computer, router, Netcenter and still Finder gives me the message after copying approximately a gig worth of data.
If you have some suggestions or thoughts, I would greatly appreciate it-
I also have a Windows 2000 and Windows XP machine on my network and they are able to copy and connect to the drive without any issues.
MacBook Pro 15" 2.16 Intel Core Duo Mac OS X (10.4.8)
MacBook Pro 15" 2.16 Intel Core Duo Mac OS X (10.4.8)
MacBook Pro 15" 2.16 Intel Core Duo   Mac OS X (10.4.8)  

I did, they said it is an issue with how OS X handles Samba connections.
Any thoughts?

  • ADUC home drive disconnected when using GPP drive mappings

    Hello,
    We have an issue with mapping home drives and using group policy preferences to map all other drives for our users.
    We have users in multiple locations and each location has it's own storage, users in a location have their home drives on that location's storage. We assign the home drive to a user using the profile tab in the ADUC user account settings (\\storage\users$\%username%).
    All other drive mappings are made through group policy preferences. This is working as expected in Windows XP.
    We are preparing for a migration to Windows 7 and Windows 7 deals with this situation in a bit different manner, for some reason when you log on to Windows 7 the ADUC account settings are made first (thus connecting the home drive) and after this the group
    policies are applied and prior to the first drive mapping being made all connected drives (and with this the home drive) are disconnected and then the drive mappings are applied. This behaviour occurs with replace mode as well as with update mode.
    To work around this the home drives could be mapped using GPP but since we have users with home drives in multiple locations and drive mappings in GPP's do not understand the %HOMESHARE%%HOMEPATH% syntax we have to use a drive mapping per location and for
    each drive mapping use item level targeting and put the users into the appropriate security group and this is more administrative burden then we'd like. Dividing users into OU's per location is not really a workable option as well.
    Has anyone seen this issue before and/or has some ideas on how to deal with this or has a workable workaround/solution ?

    Thank you for the reply. I have seen the article you linked to, from that I tested and found that in our situation we experience the same behaviour.
    The home drive is connected to P through the AD user account profile tab, the other drive mappings are gpp drive maps and are starting from G on and are set to replace, use first available, run in logged-on user's security context, remove this item when
    it is no longer applied and item level targeting is set to a security group, we have 20+ drive mappings using these settings. I have tested with setting the mapping to Update but the results are the same.
    I am able to connect to the home drive manually using a UNC mapping. When I test using F for the home drive in AD user account profile tab the problem is gone. Changing the home drive letter is not an option though because we have several applications that
    rely on that letter P.

  • External Hard Drive disconnects when I pick it up from idle.

    It started doing this recently. I'm guessing its a power issue, I recently had my logic board replaced but I narrowed down the symtom.
    When I connect my external hard drive, it works fine. No problem, I pick it up, move it all around, jiggle the wire, nothing.
    But when it is idle, then I suddenly pick it up, it suddenly disconects ONLY from idle.
    I used different wires, even replaced the HD case, gives me all the same problem.
    It never did it before, it only started happening in the past 2 months.
    I have to DJ with this laptop and hard drive so I cant be continuing to have this issue.

    Sounds like a good plan, you can never be to safe and having a second External HD is safer than one.
    The only thing that I would do different, is setup the 3T as my TimeMachine Backup and then erase and move my Photos, Videos and perhaps even iTunes Media to the 1T. That way you will have room to backup both the Internal Hard Drive and the 1T External Hard Drive to the 3T using TimeMachine.
    Take your time, study and use the > Time Machine - Frequently Asked Questions if you get stuck or aren't sure how to make the move.

  • Error code -36 when copying files to certain drives

    I want to back up my Aperture Library. I have two external fire wire drives that give me this error:
    The Finder cannot complete the operation because some of the data in Aperture Library could not be read or written. (Error code -36)
    I don't get the error when copying to my Drobo, so I believe this problem is only related to my two fire wire drives. I reformatted one of them using Disk Utility, same problem.

    Today I had the same thing happen. I was copying some large (2gb+) video files from a USB2 FAT32 external drive to my other Mac formatted external drives, first time to a firewire 400 and then tried to a USB2. At about 750mb, the transfer stopped and the EXACT same dialog box appeared.
    I ran Disk Utility on the source drive USB2 FAT32 to fix drive errors. No improvement.
    As I've had issues under SL with my optical FW DVD drives (see that thread for details), I thought may be my FW drives don't like FAT32. So I tried the Mac USB2 drive. Not working either.
    Finally, I realized I was routing the FAT32 drive into a cheap unpowered 4 port USB hub (Genesys Logic, Inc. chipset). So I unplugged the hub from the Mac Mini and inserted the FAT32 drive directly into the Mac Mini. Tada! Success was at hand. No problems transferring to either FW or USB drives.
    So this tells me there is something flaky about some devices and how they are hooked up. That is the drives and files are OK. It is Snow Leopard that has the bug.
    Mike, if you are still having problems and are comfortable using Unix CL, you may be able to use the DD command (so called "Data Dump") to transfer. This is a very robust method to transfer files and permits resumption if a transfer has died midstream. It can even transfer real corrupt files off of damaged disk drives regardless of drive format. I used DD successfully to move files off an eMac that had random hardware crashes (due to faulty counterfeit capacitors) that were interrupting the transfer.

  • External Hard drive getting errors when copying files?

    When I'm copying files to my hard drive I keep getting errors that the file is in use.  It was originally stopping at around the 167.8MB mark everytime when I try copying files over and giving me that error.  As this is a 1TB HDD I have no way of backing it up until I get to the US (currently studying in Australia).  So just wondering if anyone had ideas.
    Things I've done:
    - Tried using HDD over Firewire/USB and with other Macs still same errors
    - Tried Disk Utility and sometimes it I get no errors with the disk when I do Repair/Verify Disk or I get an error where the disk can't be unmounted
         - I get that error of unmounting when I normally unmount them and I have to unplug the HDD for it to be readable again.
    - I try copying files from it or to it, and sometimes files copy to my Computer entirely even 2GB ones, but other times it stops at random intervals, and it always   stops when copying files to the HDD that never works, usually stops at random times.  :\
    Any suggestions, help, or programs I can use for HDD repair would be great!
    Thanks a lot,

    Wondering if I could bump this up a bit, still having problems with it.

  • Error message -36 when copying large  files from Firewire drive

    I have kept several large audio files as backup on an external LaCie Firewire drive. When trying to copying them back, almost all of them starts to copy, then stops and (after a minute or so) report error message -36.
    I have run both Apple's Disktools and the latest Diskwarrior, but no errors are reported. I gues the audio files must have become corrupted... What do you suggest that I do? The contain valuable audio information that I really don't want to get lost.

  • Error when copying songs from cd to hard drive

    When I switched from a windows computer to a mac, I copied all of my itunes songs on to a data cd. When I insert the cd into my mac and try to copy the songs onto my hard drive, I get an error saying "Data Error (cyclic redundancy check)". I am pretty sure that you can copy as many songs, to as many computers as you want, but you can only authorize five computer to play the songs. Why is this error popping up? and How can I copy my songs?
    Thank You, Margaret

    "Data Error (cyclic redundancy check)"
    This means the data on the disc is not correct (a bad burn). Try again.
    Do you have an iPod or a USB stick.flash drive? You can transfer files that way.
    I would not recommend burning them to an audio CD.
    The songs were originally converted to AAC, thereby losing data (quality).
    Wif you burn to an audio CD and then reimport as AAC, you will again lose data (quality).

  • TA20831 Why do I get error code -50 when copying from one external drive to another in OSX Lion 10.7.4?

    Any pointers (apart from 'googling') would be appreciated. Thanks

    I have not yet been able to figure out what the problem is. I have checked the iMovie and other forums, both here and elsewhere on the Web, and I have not come across a single post that relates to this problem. The files I have been trying to copy are still on the external drive, and I have used the drive to store and transfer other files to and from my TiBook with no problems. But those three iMovie files, which will open and play from the external drive, STILL won't copy back onto my hard drive.
    The one thought I had involved disk space: Maybe a significant amount (30GB or more) of free space needs to be on the target drive when copying such large files. When I get to a point where I can delete some of the larger files I have been tinkering with, I'll try again.
    In the meantime, any insight from anybody into this issue will still be appreciated.

  • My hard drive crashed on my MacBook Pro crashed and I need to get my CS5 up and running on the new hard drive. I copied what I could onto an external hard drive but when I drag and drop I get directions to uninstall but the uninstall folder I have does sa

    my hard drive crashed on my MacBook Pro crashed and I need to get my CS5 up and running on the new hard drive. I copied what I could onto an external hard drive but when I drag and drop I get directions to uninstall but the uninstall folder I have does says it is an alias that is no longer present. I get error 6. I would like to get my software up and running on the laptop again please

    If you subscribed to iTunes match the songs are kept in icloud. If you didn't but you did save the actual iTunes library folder which should include the music, video, etc.  you should be able to just drag this file back to your machine in the same place and when you open iTunes it will give you a chance to identify the iTunes library folder. 
    You can test this to find out if you saved the media files or not and don't need to attach your nano to do it. 
    You are correct that once you connect the nano it will clear the existing files from it and sync it with the new iTunes library. 
    If you don't have the media files i'm not sure if/how to get them back on a windows ipod.  I have everything backed up regularly because of the horror stories I have seen & heard.

  • Moving library to external hard drive and get the error "Copying files failed. The disk could not be read from or written to"

    Hello,
    I'm moving my library to an external hard drive.
    I've made sure to use the 'Keep iTunes Media Folder Organized' option when pointing to the new library location.
    I select 'File'->'Library'->'Organize Library', I select to 'Consolidate Files', click 'OK' and get ther error message "Copying files failed. The disk could not be read from or written to".
    I've read elsewhere that there may be a corrupted file that I need to sequester somehow and perhaps add it back however I'm not certain how I can locate that file because the status window doesn't indicate which file it's attempting to transfer when the error appears.
    Any tips?
    Thank you,

    iTunes 10.6.3

    OK I figured it out!
    It was a dodgy file....I sorted the file folders by date, and as it turned out within the "compilations" folder there was a CD where only about half the tracks seemed to have been copied over. Could not have identified this simply from the time indicated on the finder folder sort, because there were several CDs copied over in the that same minute.
    I went back to the original itunes folder, deleted all the files from that CD in itunes, then also deleted all those files from the original disk and the target disk.
    Tried the "consolidate library" again, and it completed nicely. 200megs of music and videos.
    Very happy to solve this problem after 3 weeks.

  • Error Message when copying music files to Nano

    When copying an album to the Nano, I receive and error message with 4 songs left to copy off of the album. Error states: Attempting to copy to the disk "IPOD" failed. The disk could not be read from or written to. With 4 songs left to copy
    I have only used approx. 344.8 MB of memory. I tried resetting the Nano and then also deleting album and recopying and the same files back. Nothing seems to work, please help!

    If you want to use large files you have to reformat it. It will erase any data that is on the drive, If the drive will be used only with OSX, format it as Mac Extended (HFS+) Journaled with the GUID partition table.
    Start Disk Utility (Utilities Folder). Select the drive in the left column (be sure to select the drive, all the way at the left, not the volume indented below it). Select the "Partition" tab. Set "Volume Scheme" to "1 Partition". Click the "Options" button. Select "GUID Partition Table". Click the "OK" button. Enter the volume name and click the "Apply" button.

  • Finder issues when copying large amount of files to external drive

    When copying large amount of data over firewire 800, finder gives me an error that a file is in use and locks the drive up. I have to force eject. When I reopen the drive, there are a bunch of 0kb files sitting in the directory that did not get copied over. This is happens on multiple drives. I've attached a screen shot of what things look like when I reopen the drive after forcing an eject. Sometime I have to relaunch finder to get back up and running correctly. I've repaired permissions for what it's worth.
    10.6.8, by the way, 2.93 12-core, 48gb of ram, fully up to date. This has been happening for a long time, just now trying to find a solution

    Scott Oliphant wrote:
    iomega, lacie, 500GB, 1TB, etc, seems to be drive independent. I've formatted and started over with several of the drives and same thing. If I copy the files over in smaller chunks (say, 70GB) as opposed to 600GB, the problem does not happen. It's like finder is holding on to some of the info when it puts it's "ghost" on the destination drive before it's copied over and keeping the file locked when it tries to write over it.
    This may be a stretch since I have no experience with iomega and no recent experience with LaCie drives, but the different results if transfers are large or small may be a tip-off.
    I ran into something similar with Seagate GoFlex drives and the problem was heat. Virtually none of these drives are ventilated properly (i.e, no fans and not much, if any, air flow) and with extended use, they get really hot and start to generate errors. Seagate's solution is to shut the drive down when not actually in use, which doesn't always play nice with Macs. Your drives may use a different technique for temperature control, or maybe none at all. Relatively small data transfers will allow the drives to recover; very large transfers won't, and to make things worse, as the drive heats up, the transfer rate will often slow down because of the errors. That can be seen if you leave Activity Monitor open and watch the transfer rate over time (a method which Seagate tech support said was worthless because Activity Monitor was unreliable and GoFlex drives had no heat problem).
    If that's what's wrong, there really isn't any solution except using the smaller chunks of data which you've found works.

  • Hard drive fails when importing to iPhoto or copying old iPhoto files

    I am running a 2012 MBP (2.6 i7, 10GB ram). Just installed two new drives:
    - 250GB SSD that has only the OS and apps.
    - 1TB HGST drive formatted GUID Mac OS Extended Journaled (installed in the cdrw drive space-I had a previous drive working there with no issue)
    My iPhoto library contains over 57K+ photos and is 348GB in size.
    I copied about 500GB of data to the HGST drive and then started to copy my iPhoto library to the drive from my Time Machine folder (I could not figure out how to get Time Machine to restore just my photos to the HGST drive). After awhile I got an error saying the drive had unmounted and to not do that in the future. The first time I was able to remount it and try again. The second time the drive came unreadable and would not repair. So I reformatted and started over. After another failed attempt, I decided to try to copy the files form Time Machine to a different, external drive. That worked fine.
    Then, I attempted to copy the iPhoto library from that external drive to the HGST drive and it failed again.
    Finally I decided to just take all of the Originals out of the iPhoto file and put them in a different directory. Then I created a new library on the newly reformatted HGST drive. I then attempted to import the photos to the new iPhoto library. It seemed to be going fine. I left for 40 minutes, returned and the drive was again dismounted and not recognized at all in Disk Utility )I think it will reappear once I restart.
    I am able to get the iPhoto library to come up on the old external drive. It wants to rebuild the thumbnails when I start it. It does that, but not all of the thumbnails show up. I ran the repair utility and rebuilt the database. I have not tried the last rebuild option on it yet. I am hoping someone has a clue as to what might be the issue (my best guess is a/some bad images that are toasting the library. But before I spend countless more hours searching for bad images by importing in batches (which could turn into days of trial and error if it keeps munching my drive.
    The part that gets me is that I can import my music (iTunes and Logic files) of 400GB or so without a hitch. I am concerned that repeated crashing of the drive might cause errors (I am not that hardware savvy to know...)
    Any help is GREATLY appreciated! Thank you.

    I agree Terrance. However, I was able to copy other large batches of other files (my music for example) without any issues. The issue only showed up when copying iPhoto's library and/or the photos themselves. This was repeated 3 times; I copied all my other files to the drive then it unmounted on iPhoto. And, as I said, again when I started with a fresh reformat and just iPhoto. That does not seem like hardware to me if it is only happening with one set of files.
    I have managed to get the iPhoto library to work on my other external drive. It wanted a rebuild twice and a thumbnail rebuild once. I am now attempting to copy it over to the new HGST internal drive.
    Anyone have a suggestion for alternatives to iPhoto? I have aperture, maybe I will try that. But from what I understand, it just shares the same library as iPhoto.

    Did you use migration assistant to copy over programs, documents, and settings? You can't do that with PSE. Elements is not a tidy package in accordance with the apple developer guidelines. The installer strews stuff all of your hard drive in place the migration assistant isn't programmed to look and you can never hope to find all h the bits. You must always install PSE from scratch on a new machine. By attempting to copy it you have made a lot of trouble for yourself.
    You will need to download and run this:
    Use the CC Cleaner Tool to solve installation problems | CC, CS3-CS6
    and then you can go around and manually remove what you can reach. Look in applications, your hard drive>library>application support>adobe, your username>library>preferences. In the user library also delete any saved application states for PSE.
    Then you can reinstall from scratch.
