As I am in the process of building a media server, I decided to give WHS a shot. I'm NOT a fan of duplication but figured I would just "duplicate" (protect) the stuff that would be most difficult to replace. Well, after installing WHS, I added one of my drives to the storage pools. I had a "fresh" 1.5 TB drive for this purpose but mistakenly chose the wrong drive.


I didn't realize this right away and started adding folders to be duplicated. Once I realized I lost a full drive of movies (ironically, the main reason I decided to build a media server was to "protect" my movies, and now I wiped out a full hard drive), I yanked it out and started trying to recover what ever I could. As I looked in the "share" folder of this drive, I noticed the movies I added to it. I launched a few of them and was surprised that they did not work properly! They were playing in slow motion, skipping and all sorts of other issues/problems.


That's why I wanted to know if anybody else has actually lost a drive and had to rebuild with WHS. Is the integrity of the data 100%?

You might find that having removed the drive that the demigrator process has started to try to move the files around. Demigrator has been known to produce this sort of issue when it is running, have a look at thegreenbutton forums to get an idea. Maybe let everything settle down (i.e. restore what you can and give it a few hours to get its act together) before trying to play a movie.

I have replaced drives without issue in my WHS

Just let it run for a few hours. WHS is probably replacing all the files that went missing. All the folders with duplication turned on should be safe.


However, if you messed up 2 drives at the same time then there is risk of data loss. So as long as one drive fails, WHS can copy the duplicated data from the other drives, but if 2 fail at the same time, there is a chance that the duplicated data is also lost. So beware, and check if everything is still there.


I just replaced my WHS system drive after I started seeing SMART errors and bad sectors. I was lucky enough to be able to clone the drive, but since its the system drive, I still had to reinstall/ reconfigure WHS, as it saves the drive's info & IDs in the registry.


I recommend the "home server smart" addin to monitor all your drives and predict any imminent failures. The addin reports any read errors, bad sectors, high operating temperatures etc, and is usually right when a drive is about to bite the dust.
