An unknown error occurred (-50) while attempting to sync photos

Back up all data. There are several possible causes for this error. Please take each of the following steps that you haven't already tried. Stop when the problem is resolved.

Step 1

Delete the iPod Photo Cache. Quit and relaunch iTunes.

Step 2

Check the names of all albums and slideshows in iPhoto. The names should contain only plain letters and digits, not any punctuation marks or other characters. Rename them if necessary.

Step 3

Remove the soundtrack from any iPhoto slideshows that have one. If sync now works, you may be able to restore the soundtracks.

Launch the Console application in any of the following ways:

☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)

☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.

☞ Open LaunchPad. Click Utilities, then Console in the icon grid.

Make sure the title of the Console window is All Messages. If it isn't, select All Messages from the SYSTEM LOG QUERIES menu on the left. If you don't see that menu, select

View ▹ Show Log List

from the menu bar.

Click the Clear Display icon in the toolbar. Then try the action that you're having trouble with again. Select any messages that appear in the Console window. Copy them to the Clipboard by pressing the key combination command-C. Paste into a reply to this message (command-V).

noone can help us?

Totaly disappointed by apple.I open a ticket 2 months ago, non reply, no troubleshooting, no solutions.

there is also a bug open from 2 years, no solutions for that too!!!

I give to apple all capture data, all logs that they ask to me...I have given full cooperation, it's not the same from them!!!

I have found a way to sync photos to your iPhone/iPad/iPod.

Change your sync location from iPhoto to something else

I have chosen the pictures folder. Just put your pictures into that folder and it should work. It worked for me

it works also for me.

There's only one problem..photos aren't arrange in folder, i have more then 15,000 photos on ipad, it's hard for me to find a photo! 😟

this is the first step, i wait for apple to solve this bug!

where is apple support??no answer to this problem?i contact apple support in these days and they have still no answer yet!they make me do the same things that i made the last and previous time.they don't tell me if it's possible to recreat that error, they told me nothing, i gave them log, test and anything thay aske me!!

they told me that the engineers are analyzing the problem, they repeat this for a month! they told me the same thinks about a bug that i open 2 years ago and it's still present.

i have already tried that but it doesn't works for me 😟

i only rebuild library with iPhoto Library manager, what operations did you do?

in italy the genius aren't so skilled like yours....they don't know that solutions. 😟
