I did a forum search and came up Empty. I have a 2TB WD My book essential formatted NTFS. I had about 300gigs of Movies, pictures and MP3's and all was fine. I loaded a couple hundred gigs more of movies and now after reading the drive I get a note in the top of the screen status bar that says "Failure to Aggregate Drive" It does read and play the movies I added but I'm concerned about the msg. I don't want to get this completely loaded and have it crash before I get it all backed up.....

It has nothig to do with the drive, the drive is good...try deleting .wdtv folder from it.happened to me only once...

Thanks Mytbyte! That did the trick! The manual only says the error can be caused by a variety of things.....

I was a same problem, but even my PC coudnt read external disk anymore. So I was very affraid that I lose all my important pictures and other files. I searc on the net 2 days and find solution what helps me. On the command line (Start-> Run ) I wrote : chkdsk X: /f ( X is drive) Now it works again. Sorry for my english. Krunge
