operation can’t be completed because you don’t have permission to access...

Great work afinno! Works for me copying data from my old MBP to my new one via with the old one in target drive mode.

One thing to note is that there's no status, or working, or coping feedback other than watching the files appear in the "to" folder and the XXX.XX GB available slowly tick downward.

I feel like it will be pointless to post to this thread, since I've read every page and nobody has found a solution, but I am having a very similar problem. Same error message, but here are the differences:

• The problem did not occur until some time after I updated to 10.6.7 from whatever came before that.
• I am not using a linux server. I am using a PowerMac G4 running 10.4 as a file server.
• The problem also occurs when copying files from an external USB hard drive onto my MacBook Pro and vice versa.

I upgraded from 10.5 to 10.6 a few months ago in hopes of having a more efficient machine, but so far 10.6 has been nothing but trouble for me. I'm definitely not going to upgrade to Lion, at least not for some time.

I've also hit this problem doing something I've done in the past with no problem, so the suspicion must be that it came along with an upgrade. My suspicion is that it is something to do with the number of files being copied. My attempt to copy a folder with 10 or so subfolders crashes about half way through. When I look on my storage device, I find that the first few folders have copied OK and the next folder is half complete. I now manage the job with no interruptions by creating an empty folder on my storage device and then copying across each sub folder. I can set all the subfolder copies going simultaneously without causing a problem. But it would be nice if Apple fixed this soon.

I found that my LaCie array had a bad power supply; that may be the problem for you. It could be that by copying in smaller chunks, you're taxing the power supply less, and therefore avoiding causing the array to crash. But it seems like a lot of work on your part to make something happen on the array that should just work!

My array was still under warranty, so LaCie replaced it.

Hey everyone,

Was having the same problem and the easiest way for my situation was just to just make sure your mounting your destination drive using SMB (not the default AFP).

So, if copy data over the network, just hit Apple+K and type "smb://destination.ip.address" (you'll have to enable SMB file sharing on destination mac) then just mount the drive and copy away.

Don't know if this problem was ever resolved because I'm running Mavericks on my iMac and 6 months ago I had no problem saving and opening files using Adobe Photoshop CS4. It seems that since Christmas 2013 roughly... I can no longer store or open files that are in my NAS drives.

If I open Finder, the NAS drives show up and I can open any/all files by selecting "Open In: Photoshop CS4". If I attempt to "Open" any type file (PSD, PDF, JPG, TIFF, etc.) created 6 months ago in Photoshop... the NAS drive where the folder/files are stored doesn't show up in the left hand column.

Some people say the only real workaround is to copy all your files to a large (like 1TB) USB drive and then when your finished with your changes or whatever... save the files to the USB drive, then copy them to the NAS drive. That seems like a real PITA and a kludge approach especially to a designer trying to not waste time.

I don't know enough about computers to know the difference between a SMB mounted drive or a AFP mounted drive and when you have 1 TB of stored files on a NAS drive whether its practical or even doable to switch with all those files being at risk.

The mere fact that before OS X 10.6 this worked fine means that its something to do with Apple's code. My CS4 Suite has been running just fine since I installed it some years ago. I will continue looking for a fix that the average guy can actually implement.

Just wanted to say, it's 2015 and this problem still happens.

BUT the good news is that afinno's solution from April 6, 2010, still works!

Here's a user-friendly step-by-step explanation for anyone who's not terribly familiar with Terminal.

WHAT YOU'RE TRYING TO DO:

Transfer files to an external hard drive (actually transferring from one external hard drive to another).

PROBLEM:

You got this error message with a few files:

“The operation can't be completed because you don't have permission to access [file name]…"

SOLUTION:

1) Take note of the file name on the error message. In the Finder, use "search" to find it on the volume you are transferring it FROM.

(make sure it's the right folder - best to try to narrow down as much as possible which folder it's in. Usually you can tell by looking in the volume you transferred TO, what was the last folder that was transferred. )

2) Find the folder on the volume you want to transfer it TO.

3) Open Terminal.

a) Type in these characters (yes, include a space after the "p"): cp -RX

b) Now, type a space after the “X".

c) Physically drag the file you want to transfer (the one that was on the error message) from the finder right onto the top of the Terminal window. (This is a handy alternative to typing in the file and its directory.)

d) Drag the destination folder (the one on the volume you want the file to go TO) onto the Terminal window. (Note: you don't need to type a space, or anything else for that matter.)

e) Hit “Enter”.

f) Check in finder to make sure that it worked. (You should see the file in the destination folder.)

g) Ta-da!!! You did it!

h) Now make sure the rest of the files in there get transferred. You may end up buried a few levels deep in folders, so just take care to make sure it all gets transferred over, because it just stops in its tracks when there's one file that returns the error.

This is still a problem since 2010!?

Trying to make changes to my Seagate NAS, simply adding a color dot or deleting a file. Very frustrating. I have no Terminal skills and prefer not to use it. Guess I'm just stuck.
