    I am running Windows Home Server 'vail'  the original beta release.  It's running on an Intel Dual Core e2180 and 2 gigs of DDR2.  My system drive is a 2tb Western Digital Green EARS, and a second 2tb Western Digital Green EADS for duplication.  All folders are duplicated.

    I am getting errors stating a 'Data error was detected on some of the files or directories in server storage' then in states 'An uncorrectable data error was detected on one or more of the following files or directories in server storage'  Then it lists 5 files that have 'uncorrectable' errors, but then when I browse the directories these files are fine.  Does this mean the pictures are good on the duplicated copy?  I would think uncorrectable would mean that it is lost forever.

    It appears you are having the known problems of using the advanced format disk in home server. This is especially applicable to using them for the system drive.

    If you are able to copy your data to an external drive. You may get away with using the older style EADS drive as the system drive and the EARS drive as the pool. Searching in this forum should find posts that cover using the advanced format disks in the pool.

    Microsoft has recently released information recommending that you avoid the advanced format disks in WHS.

    I do not personally have any yet so can only pass on what I have read.

    ...] Does this mean the pictures are good on the duplicated copy?  I would think uncorrectable would mean that it is lost forever.

    Actually I am not sure what the correct answer is, but I think you have to read this as folows:

    1. The integrity of the files in question can not be garanteed (if possible, fall back to it's latest backup copy)
    2. The data on the disk in question is deteriating and at risk: resolve the problem or replace the disk a.s.a.p.

    Dave's remark on Advanced Format disks applies to WHS v1 only. According to this article (KB2385637 = "Information regarding Windows Home Server and advanced format hard disks") VAIL does support Advanced Format disks.

    No home server like Home Server

    Now I am getting errors on my EADS drive, but it doesn't show which files are affected.  I wonder if the SATA controller is bad, or if my memory is bad...  I have other copies of everything, but I really liked the idea of WHS vail keeping check on silent errors.  At least it's telling me its losing my files.
