Consolidation error "Copying Music failed. An unknown error occurred (-51)

I want to Consolidate my large music library and add all of the songs from my MacBook to my new, much larger iTunes music folder, which is on a Buffalo Terastation NAS, so that I may easily back them up. When I "Consolidate", I immediately get an error message that says "Copying Music failed. An unknown error occurred (-51)."
Has anyone else experienced this and knows how to fix it? I can't seem to find a fix for that error code.

I found this link about error numbers here ...

Error # 51 means that the Buffalo Terastation NAS is unreachable on your local network.

Error # 48 means that the "Address already in use". Is your External Hard Drive connected by Firewire or Ethernet?

Look at this Apple Article about how to Consolidate the iTunes Library ... http://support.apple.com/kb/HT1449
If you follow the steps in this link I think that it should work. But first you must setup the Hard Drives as a 'Bootable GUID Partition Table' with 'Owners' & 'Journaling' Enabled in order to retain the iTunes users permissions.
Good Luck.

Error "COPYING MUSIC FAILED. The disk could not be read from or written to"

After following the procedurest to move the iTunes music, the computer started whirring away, happily copying and consolidating all the song files to the new target folder.
After copying 68gigs of 130gigs perfectly, it stopped dead and the following iTunes error message appeared:
"COPYING MUSIC FAILED. THE DISK COULD NOT BE READ FROM OR WRITTEN TO"
I am copying to an external LaCie 500g hard disk, and the current music file is split between folders on the laptop and folders and a 2nd external LaCie Hard disk. It did not appear to have any problems copying and consolidating files from both locations, until the error message showed up.
How can I solve this?
I really need to consolidate this music file.
macbook pro Mac OS X (10.4.6)

OK I figured it out!
It was a dodgy file....I sorted the file folders by date, and as it turned out within the "compilations" folder there was a CD where only about half the tracks seemed to have been copied over. Could not have identified this simply from the time indicated on the finder folder sort, because there were several CDs copied over in the that same minute.
I went back to the original itunes folder, deleted all the files from that CD in itunes, then also deleted all those files from the original disk and the target disk.
Tried the "consolidate library" again, and it completed nicely. 200megs of music and videos.
Very happy to solve this problem after 3 weeks.

Copy files failed: An unknown error occurred (-50), copy files failed: An unknown error occurred (-50)

Can't consolidate my library. Any clue as to the fix?

Do you have a line number? The script prossibly makes an unjustified assumption that the Album Artist field always exists though I thought I'd covered that one.
Looking at the script there are two locations where the value of .AlbumArtist is read - the second one shouldn't ever cause an error. The first one has never done so for me, but I suppose it is possible if the "first" track in your library isn't a standard audio track...
If the error line is 143 would you mind adding the following line of code before the current line:
If I=1 Then MsgBox .Name ' (letter i = numeral 1)
Can you find the object with that name in the library, and if so what kind of object is it?

Copying music failed, unknown error (-50)

Trying to move my library from one external hard drive to another external hard drive. Did it by going to Preferences-Advanced and changing the drive/folder location and then going to Advanced-Consolidate Library. All seemed to be going ok and then the process stopped (about 40% done) with the error "copying music failed. An unknown error has occurred (-50)". I've searched the forums and Google without luck. There was some mention of filenames. However, the songs with the longest pathname made it over to the new drive just fine. So it's not length. A quick check in iTunes using "GetInfo" showed some songs on the old drive and some on the new drive. At what point do these get updated in the consolidation process? As they are getting copied (one song at a time) or all songs before the copying process starts???
For the moment, I have changed the drive back and consolidated the library back to the original drive and that seems to be ok. Still want to move the library but don't know what caused it to stop the first time so thought I'd ask here before trying again.
Thanks.

hi usablues!
hmmmm. i've been seeing this particular kind of "anomalous" (-50) off and on since 4.9.
this is experimental. but we've been seeing different sorts of strange unknown error codes under similar circumstances when antivirus or antispyware is interfering with itunes' ability to read the library files.
... so ... can you get a consolidate to go through properly if you have your antivirus/antispyware switched off?

Problem consolidating to NAS "Copying Music Failed"

Can someone offer advice on how to solve a problem with iTunes for Windows? I get an error message when I consolidate. Error is "Copying Music failed. The disk could not read from or written to". I have a laptop and the HD is full. I bought an Infrant ReadyNAS NV+ 1TB. I have copied files to the NAS without any problem. I followed Apple's Written Help Instructions to "Moving your ITunes folder". I followed the instructions and got the error above "Copying Music Failed...". Preferences->Advanced..Itunes Music Folder Location...change...<\\NAS..
Itunes Music>. Also enabled Keep Itunes Music folder organized. Disabled Copy Files to Itunes Music..... Then went to Menu Advanced->Consolidate Library. I then get the error "Copying Music failed. The disk could not read from or written to". The NAS from Infrant was simple to install on my home LAN. There must be something simple that I am missing. The NAS was easy to install. And I have been transferring Word/Excel/etc files like crazy to the NAS to store. I cannot figure out why the instructions from Apple do not work? I cannot figure out why the consolidate Library function fails. Any advice would be appreciated.

I have found with network storage that mapping a drive letter to a folder on the network storage drive works with iTunes. Couldn't get iTunes to access network storage without mapping drive.

Copying Music failed. The disk could not be read from or written to.

I just added a server to my home network. It's called "DELLSEVER" and is networked via TCP/IP on a Windows Network. I can copy files to and from it no problem. I created a shared folder on the server with public read/write access and no password called "Music".
I wanted to move my iTunes music folder (~110GB) to the server's Music folder.
I followed the instruction found on this forum and went into iTunes(6.0.4.2) preferences -> Advenced -> Itunes Music folder location -> clicked Change -> selected the directory from the available list -> clicked ok.
Under "iTunes Music folder location" it now says "\\DELLSERVER\Music\iTunes", and clicked ok to close the preferences.
I then clicked Advanced -> Consolidate Library -> Consolidate.
I then get the error "Copying Music failed. The disk could not be read from or written to."
I then tried to manually copy my library from dragging the folded from my PC to the server. That worked fine, but I can't get iTunes to use the server's copy of the music, it keeps going back to my PC's copy.
Please help. I've only got about 30 Meg left on my PC's drive with iTunes and need to relocate my music to the server's drives.
And if it matters, I am Administrator on both my PC and the server.
I also tried de-authorizing my PC just in case. Made no difference.

Thanks Katrina. Mapping the folder to a drive letter allowed iTunes to start copying the music across.
Unfortuntely iTunes didn't notice that I manually copied the files across earlier, so it's overwriting them. I'm about two hours into the transfer with about another hour to go, but it looks like it's going to work.

ITunes library consolidation error: "Copying files failed. An unknown error occurred (-50)."

My iTunes library has outgrown the HDD on my iMac, so I've started to migrate it over to a Synology NAS. The iTunes Media folder is set to the NAS, but when I attempt to consolidate the library the operation fails each time with the error: "Copying files failed. An unknown error occurred (-50).
I have found this references to this error in the communities from Windows users, but I only use Macs.

Just trying to give this topic a poke as I am having a similar issue.
I am rebuilding my library that was on an external drive. I had a backup of much of the files, but not a direct backup of the iTunes media folder, as well I am now moving it to a new iTunes Media directory on a Synology 1813+ NAS running DSM 4.3 vs. a USB attached drive.
I have followed all of the correct procedures to move the media directory by using the tools within iTunes, and that all worked perfectly.
So far iTunes has been able to locate most of the music files through its own processes. Once it completed that process I then initiated "Consolidate files" to move the found files to the new iTunes Media directory on the new NAS.
I am led to believe that the issue is with a specific file that causes the copy process to stop, but I don't know how to capture what file it might be.
I am not seeing anything relevent in the console log.
Hoping someone can throw me some ideas...

BUMP
Yes, I just get that message. I don't see how I could investigate this problem.
I didn't mention that this happened when I was consolidating my library, not copying files to another computer.
In other words, I'm using a "normal" itunes procedure, itunes won't complete it, and won't tell me exactly why or how to figure out how to fix it...
Is there at least some easy way to tell which files were successfully copied to my itunes music folder so I can work on moving the uncopied files?
Can anybody help me?

I'm getting error "copying files failed. the required file is in use". How do I find the file?

I've found this question is elswhere but no answers. I'm trying to consolidate my library to an external hard drive since I'm pretty sure my current drive is about to fail. The entire process has taken me days due to one error or another. This is my most recent error and so far there is no way around it since it does not show me what file is in use.
Help?

I used "Carbon Copy Cloner" to copy my library from one external disk to another.
The "library" consists of a bunch of files and folders (see links at end). You don't need CCC to copy it, just drag the whole iTunes folder in your Home > Music from one drive to the other.
I pointed my iTunes library to the new location under iTunes preferences.
No, don't do it with preferences. Once you have moved the folder as above, start iTunes with the option key held down and guide it to the library.itl file on the new drive. This is assuming you have been using iTunes's default settings and haven't been managing your media yourself.
I used iTunes to "Consolidate Library" to verify that all files had been moved.
Okay, in doing that you have moved just your media to the new drive but left all your other library files on the old drive.
iTunes succesfully copied/re-attached a lot of files before giving me the error that the disk could not be read or written to.
Try it with my method.
I began to troubleshoot the hard drive by checking the cables and scanning for errors.
This disk checked out fine.
I identified the failure and subsequent error was due to corrupted files.
I watched the consolidation process and was able to see which file it was trying to copy before it errored out.
I deleted the corrupted file and restarted the process (I repeated this numerous times).
When the process seemed to be just about over, I got the error "Copying files failed. The required file is in use."
I'm sure this is likely another corrupted file, however, it happens so fast that I have no way to identify what file is causing the problem. I tried making sure no other processes were running and no other windows or media players were open. I also tried to look for an error log but was unsuccessful.
Any ideas?
Disk Utility will scan for a corrupt directory but I don't think it works on the file level if it is a single file that was corrupted. I know I have seen Carbon Copy Cloner pick up on single file error when I had one sitting on a bad sector of a drive several years ago. If you can identify the corrupt file this way then you will have to use a backup copy since it is unlikely it can be rescued.
If you have Diskwarrior it has a file check utility.
You have, of course, restarted your computer before doing all this, and keep other computer activity to a minimum (don't play music while copying the files and don't use other applications that coupld potential be trying to get access to your files)?

By the way, i am using Windows 7 x64 and updated itunes

The creation of the shadow copy on the backup destination has failed. Detailed Error: The Volume Shadow Copy operation failed with the error 0x80042316

When using Microsoft Backup on a Windows Server 2008 SP2 (not R2 - [Microsoft version 6.0.6002]) I get the error "The creation of the shadow copy on the backup destination has failed. Detailed Error: The Volume Shadow Copy operation failed with the
error 0x80042316"
The odd thing is that when I start the backup manually, it works fine. When it runs automatically the error appears.
When doing a SFC /scannow I do get errors that can't be corrected.
Is there anything short of rebuilding this machine (It's a DC and the only one this office has) I can do to fix this?

Hi,
0x80042316 means "Another shadow copy creation is already in progress". This error could occur when another VSS instance is running.
Is there any third party backup application installed? Try to uninstall it to see the result. And please also check if there is another backup schedule which causes the conflict.
Meanwhile please provide the result of:
vssadmin list providers
vssadmin list writers
Please remember to mark the replies as answers if they help and un-mark them if they provide no help. If you have feedback for TechNet Support, contact [email protected].
Hi,
I do have Crashplan ProE running. It started at 1900 and the Windows Backup starts at 2000. I have modified Crashplan not to start until 2300 to see if that helps.

The above you are talking about refers to instructions for Snow Leopard (10.6) and you did post in the Snow Leopard forum area.
Your system profile confirms you are actually using Lion (10.7.1). Therefore, you should seach for Lion instructions in the Apple's Knowledge Base or post over in the Mac OS X v10.7 Lion forum area.

VIN 2 - Access failed. Unknown error...

Hi all,
I made the deployment of VIN 2.0. Apparently all is well. I entered the license and enabled the discovery. After the first moments when VIN shows the message "First Discovery pending ..." then I get out of all VMs, including the same VIN, the message "Access failed. Unknown error while retrieving data from Infrastructure Navigator".
Any suggestions? I tried to restart it several times.
Matrix

Hi Matrix,
There could be many reasons for this.
Please check for the following:
1. Does the VIN VA have access to the VC?
2. Is the above VC configured to use non standard ports for HTTP/HTTPS communication (not 80/443)?
3. Does the VIN VA have access to the ESX hosts that host those VMs?
Have you contacted your sales engineer / PSO regarding this issue?
Is there an SR open on this?
It will be very helpful to get a support package from the VA to analyze what happened, as this is a very general error.
Regards,
Boris
