Cannot copy "Data Rescue 3" to USB stick

I'd like to have a USB stick with a couple of utilities, Data Rescue 3 being one of them. However, it is not possible to copy the application to a USB stick. The copy process gets always interrupted with with the error message "The operation can’t be completed because you don’t have permission to access “Data Rescue 3”".

I have several times set the rights for the application file to 777 (drwxrwxrwx) and also cleared the ACLs and the xatts. However, when I look at the file with Terminal it shows "drwxrwxrwx@" and the @ usually means that there are still extended file attributes.

Strange is that I can copy the file from Applications to the Desktop but I cannot copy it from Applications or the Desktop to a USB stick.

Does anybody know what is going on here and how I can force this file onto a USB stick? I guess it will certainly be possible as root. However, I have had things like this already several times and would like to find a way to copy such a file as a normal (admin) user.

I found a workaround by compressing the application file, copying the zip file onto the USB drive and decompressing it there. But I still would like to know what is going on here...

Have you tried asking Prosoft?

I rather don't because I would prefer that they don't try to close the "zip-copy-unzip" hole.

By the way - Data Rescue works without problems when started from the USB stick.
