whenever I try co copy files in snow leopard to an external hard drive, i get in most of the cases "the operation can't be completed because you don't have permission to access"

I even tried to do this through BASH, but it just stops. Is it possible to get bash debug messages? Do oyu know the workaround to this?

  • maybe the files you're trying to copy are locked? cmd + i should give you an idea.

Is there enough room on the external hard drive? Are you trying to copy a very large file? Try creating a simple new test folder on both sides (hard drive and external drive), do you get the error?

Is this a restored os from time machine? (if so see http://discussions.apple.com/thread.jspa?threadID=2253608&tstart=0)

Is external hard drive over wireless or local, if wireless try doing it local.

Is the external drive formatted NTFS?

If so by default you don't have rights to write to the drive, only reading. You will need to install an applications like NTFS-3G for Mac which will allow you write access to an NTFS drive.

  • no, it is Mac OS Extended (Journaled) formatted Feb 20, 2010 at 14:51
  • Fair enough. I am however leaving my answer in case someone does have a problem with a NTFS drive. I have never had a problem with Mac formatted external drives on Snow Leopard. Feb 20, 2010 at 15:02

Your running into cross platform issues... If I am reading this correctly.

Can you please verify that I am following the multiple threads here?

1 - The drive your trying to copy onto is a Mac OS Extended formatted disk? 2 - The disk you are trying to read is a NTFS or Fat32 Windows XP system disk

It sounds like your running into a filename incompt. issue. For example, on the Mac you can have a filename of "this is a great/\filename". But if you copy that to a PC, it'll freak out, and probably create a subdirectory (the ).

Same thing on the PC to Mac side, there a few characters that don't transfer well. It's less common on the Mac, because they have less restrictive filenames. But for example, don't use "::" as a filename...

My suggestion is to use the right tool... Download Winclone, and use that to clone the disk to a disk image... 1, it'll be compressed, 2, you can open the disk image, and retrieve any specific files you need, when you need them. 3, you can always clone the image, to a disk drive, if you want to boot from it...
