Apple Says It Should Copy ... Why Won't It?

Why Can't I Copy My iTunes Library to an External Drive?

Hi, I'm trying to back up my iTunes library to an external (WD MyBook) 320 GB USB drive (because I'd rather back it up than do the cumbersome method of backing it up to DVD/CD that iTunes 8 provides. For some reason, every time I try to copy the folder over, Windows XP Pro SP3 (on my laptop) insists that it can't copy it, but the error doesn't specify the specific folder or file it's hanging on.

I'm running off my Administrator account on the laptop, so it shouldn't be a rights/permissions issue. I'd really like to back it up in case I ever have to upgrade, so if someone could suggest why Windows isn't allowing me to copy the folder over, I would appreciate it.

Do you have iTunes open when trying to copy it over? That might prevent it from copying because the files are in use. You could also try using TeraCopy for handling the copying, it speeds up copying under windows.

Can you copy other files/folders to the drive? Try copying some other random file and see if it complains about that.

I have done this as well as set up two additional laptops for purposes of synching--there are a number of online tutorials--you might try this one. I tried a number of different tutorials until I found one that worked for me. Good Luck

Response by poster: Hi again,

For answers so far: No, I don't have iTunes open, and yes, I can't copy other files/folders to the drive. I forgot to mention that I was able to copy over the iTunes database files, just not the actual media.

Another thing that might be causing an issue: I have an iPhone, rather than an iPod, and I also have apps and downloaded video stored in my iTunes folder as well.

Response by poster: Whoops ... make that "can" copy other files/folders to the drive.

have you ever reformatted your external drive? if not, there's a good chance it's formatted FAT32 (which works on PCs and Macs). if it is, there's a 4GB file size limit, and you might have a video file in your library that's larger than that and tripping up your file copy. if you reformat using NTFS, you won't have to worry about file size limits. what's the specific error message you're getting?

alternatively, you can use xcopy from the command line; it can be set to not stop on errors.

Response by poster: Thanks for the continued responses:

So far:

1)It's not an iTunes processes issue; right after startup, I killed every iTunes/iPod related process that was running and attempted to copy. No luck there.

2)It might be a permissions/flag set issue. Even though I am running as Administrator, I have noticed that the read-only flag is set for these directories, and even though I remove that flag for folders and sub-folders, the flag remains set (though from what I've read, this may be a red-herring).

3)The drive is new out of the box, so it's never been reformatted to NTFS. For mrg, the message I'm getting is the Windows dialog: "Error Copying File or Folder". The error itself is "Cannot copy file:" and that's it. No additional information or file/folders are specified. I get the error even when just trying to copy the iTunes music folder (which is a 12 GB file, incidentially).
