I recently bought an I-0 Data 1.0TB HD for extra backup and storage. I have been using synctoy to regularly backup my important files and folders from my main laptop. Every time I run synctoy (I usually do so in the "contribute" mode), I get a "corrupt file" response. In addition, my backup procedure quits and it says "Exception during preview: The FileSyncProvider failed while detecting changes." Although I was originally able to syncronize my laptop files and folders with the HD, I can no longer finish a simple "contribute" task. I have another 160GB HD (Buffalo) which works just fine in the same manner. I had another 250GB HD that also failed completely on me and I can no longer use it either.

Can any tell me what the problem is and how to rectify it?
