trying to copy, it is possible that there are "invisible" files in there that don't like something.
Presuming a single document can transfer OK, then try multiple documents. If there are multiple subdirectories, try a single subdirectory first, with no subdirectories in it - only documents... find out where the error message hits.
It is also possible that the naming convention used for the memory card has some sort of odd requirement... Did you ever format the card or just plug and play?
hello.
i am a photographer and a new mac user.
as the title says, i'm having trouble transfering a folder into my external hardrive.
i have two usb devices going. one is a compact flash card reader and the other is an external hard drive. i'm trying to copy the card reader's files into my external hard drive.
i've tried copying the folder by simply dragging the folder from the CF card reader to the external hard drive but it won't let me. there is always a message telling me i cannot. this is what i get;
[the item "foldername" could not be moved because "USB-HDD" cannot be modified]
i have various sub folders in the external device i wish my folder to be put in but no matter where i drag it to it'll keep saying the above statement.
i have even tried copying the files onto my desktop first and then dragging it to my external but the same message appears.
how am i supposed back up my files if my storage device "cannot be modified?"
thanks.
