Thanks for the response drashna. I decided to move the data off that drive, drop the volume, recreate it, and then format it. I am at that stage now, and am running a few tests on the drive with the Seatools app. I really don't think anything is physically wrong with the drive (chkdsk has come back clean several times). But I want to make sure. A couple or few questions if I may .... 1) do you have any idea why a disk would suddenly change to 'unknown' status in whs? 2) if re-initializing wasn't the correct way to fix an unknown disk, then what is a better solution? (keep in mind, the drive was not accessible from explorer, or any other way I could think of). 3) once I finish testing the disk (and assuming all is well), then I have to continue your steps above at step 6. do i then move the contents back into my virtual pool drive (in my case, my pool is K:), or back into the "PoolPart..." folders on the 3TB disk once it is readded to the pool? 4) how do I avoid extra duplicates in the recovery scenerio? My own theory for #'s 3 & 4 is make sure real-time duplication is turned off, and then copy the files onto the new drive. Then turn duplication back on. I believe drivepool is smart enough to look for duplicate files, and won't duplicate them again (making them triplicates). But as I said ... this is a theory, and I don't have enough info to feel comfortable risking my data (some of which is unduplicated, and was on that 3TB drive).

Hi. I am currently having a problem with my pool, running on WHS2011. Hope someone can help. WHS started to complain about 1 of the disks being missing. I checked the dashboard, and sure enough, my 3TB drive was no longer listed. So i RD into the server, and fired up the Windows disk management tool. The drive was there, but listed as 'unknown'. I searched the internet (including, and especially, this site), and the best suggesting was to initialize the disk. Many posts suggested the data would be safe ... so I did that. My 3TB drive reappeared, and the data seems to be ok. However, I have a bit of a hangover issue, whereby, the data from that drive seems to be included in the pool, and, the system is writing new data to the 3TB drive as if it is in the pool, however, the drive is listed under 'Not in Pool / Drives that can be added to the pool', and I can neither add it, nor remove it from the pool. I would like to add a new 4TB drive (to replace a different 2TB drive), but would like to fix the problem with the 3TB drive before I do that. Thanks!
