[Micronet] Strange iPad Sync Error

Mike Friedman
Folks,

I've recently (in the past couple of weeks or so) been getting an unusual iTunes error message when I sync my iPad.  The message occurs after the sync (and backup) have apparently completed, although I'm concerned that whatever is causing the error message might be adversely affecting the result of the sync.

Here's the text of the message, which appears in a popup window (that must be dismissed by clicking 'OK'):
Attempting to copy to the disk "DATA" failed.  An unknown error occurred (-54)
("DATA" is just the name of my D disk, where I keep most of my stuff).

I've already checked that I have "Full Control" permissions (as an admin) on my entire "iTunes" folder and its sub folders.  Anyway, this problem doesn't occur when I sync my iPhone.

I should also say that I don't sync a lot of things.  For example, I don't sync Contacts or Calendars.  Mostly what I sync is apps and their data.

My iPad (and iPhone) are running the most current iOS version (9.2.1).  Also, my iTunes is current (version 12.3.2.35, 64-bit, on Windows 10).

Does anyone have any ideas about this?

Thanks.

Mike

Re: [Micronet] Strange iPad Sync Error

Hi,

I believe I've fixed my problem (see below for my original report), so, for the record, I figured I'd say something about my resolution, in case anyone's interested.

It seems that my iTunes iBooks repository (for my iPad only) had become corrupted.  About a couple of weeks ago I added some PDFs to iBooks on my iPad, which I had never done before.   In the course of doing this, I found that iBooks, unfortunately, doesn't allow renaming a document, so, in order to change the name of one particular file, I wound up deleting and then uploading the same document under different names, or different versions of the document under the same name.  Eventually, I noticed that iTunes continued to show several versions of the document, some with the same name and some with other names, even after I'd deleted all of them from my iPad.  I didn't know much about iBooks and how "syncing" of books worked, but I soon discovered that my book collection (including the aforementioned PDFs) resides in the Apple Store.  So, I deleted all he spurious entries from there.

But this still didn't get rid of the Error -54 problem when syncing my iPad.  Finally, I decided to turn off syncing of books altogether, which causes all books to be removed from the iPad (but they're still left in the Store).  Then I reinstated book syncing, which caused all my selected books to be downloaded to the iPad again (via iTunes).  Apparently this cleaned up the iTunes iBooks repository and the Error -54 message went way!  I have now done several regular backups and syncs of my iPad and I no longer get the error message, so I figure the problem is gone.

Thanks to Aron Roberts for the suggestions he sent me by private mail.  Although none of the various recommendations to which Aron referred me turned out to be fixes for the problem, following them probably cleaned up some things in iTunes and, in any case, ruled out possible causes of the problem, forcing me to look elsewhere.
