  Error-50 code when attempting video file transfer to Cache-A LTO4 Device

  Posted by Stanton Kellam on July 28, 2015 at 9:24 am

  I am trying to transfer video files to my LTO Cache-A device and the transfers are failing. The error message I get is: ““The Operation can’t be completed because an unexpected error occurred. (error code -50) ” It is not one particular file but different files from different external drives. Any ideas on what could be going on? I have tried different Mac’s and the Cache-A has new drives and latest software. The Mac and Cache-A device are networked using a Belkin router. I appreciate any advice from active Cache-A / Mac users.

  Hi Stanton,

  This problem may or may not be the one documented in the user manual – did you try that solution? If not, let me know, there may be other things to try.

  User Manual on Error -50:

  Macintosh issues with the LTFS Volume:
  Mac OS versions may have issues with what they refer to as “named streams” when dropping folders onto the LTFS Volume and cause the Mac Finder to report an “Error -50” upon dropping content onto the LTFS Volume. If you see this error, you can eliminate it by following the steps in the Apple Knowledge Base report covering this topic:

  To disable named streams as a default for all Mac OS X client user accounts on a Mac
  Log in to Mac OS X with an admin user account if you aren’t already logged in as an admin, then execute these two commands in Terminal:

  echo “[default]” | sudo tee -a /etc/nsmb.conf
  
echo “streams=no” | sudo tee -a /etc/nsmb.conf

  Note that if it was mounted, you will have to unmount and remount the Cache-A share after applying these terminal commands.
  For more information about this issue and other options for dealing with it, please refer to the information posted at https://support.apple.com/kb/HT4017 on the Apple web site.
  This issue can also be avoided by mounting a Macintosh share on the Cache-A appliance with the Mount Manager facility, and using the File Manager in the web user interface for your operations.

  I really appreciate the help Tom. Not being a code guy I have some questions with the commands:

  echo “[default]” | sudo tee -a /etc/nsmb.conf
  
echo “streams=no” | sudo tee -a /etc/nsmb.conf

  I assume the “[default]” is entered exactly like that or is [default] something else?

  Also – what is the character “I” between “[default]” and sudo tee. Is it a capital I or a 1 or a Lower case L?

  Thanks for the clarification. – sk

  Sorry for the confusion,

  Yes – use “[default]” exactly as it appears

  The vertical bar is called a “pipe” sign in Linux/Unix (and Mac) and is typed with the shift-backslash on a mac keyboard

  You can actually copy and paste the commands from my post to do this most easily.

  Good Luck!
