I was trying to copy some files a friend gave me (i also use my mp3 as a thumb drive) and windows went stupid so i was forced to restart my computer. Then when i tried to access my mp3 again it told me i had to format it, which i did since i had other copy's of my songs. now my computer won't even regester it's there and when i try to turn the mp3 itslef on it loads to 20% and starts again. I'm pretty sure formatting it wasn't the problem since the user info that came with it recomends formatting as a quick way to remove the data but i've really got no idea wat happened. My sisters (same model) also died like this a while ago, though i don't know what she was doing when it happened.

i had the same problem with my yp-u1z - its the firmware thats broke - not the player - just go to samsunds web page (http://org.downloadcenter.samsung.com/downloadfile/ContentsFile.aspx?CDSite=us&CttFileID=636367&CDCttType=FM&ModelType=N&ModelName=YP-U1Z&VPath=FM/200611/20061106160248937_YP-u1_V3152_OC.zip), and download the newest firmware - intstall it, plug in your player, lanch the app you just installed, start the upgrade process, cheack the formatting option and wait till it's done - tere you go - it should work just fine, listen to music, be happy :D
