This is a complicated topic. 
 
 
The damaged sectors on the disk are ones that StableBit Scanner found were unreadable.  This could be an intermittent issue (such as communication issues with the disk), or it could be damage on the drive. 
 
Either way, if this is occuring, most likely you will not be able to properly read any affected files.  In fact, if you try copying a file that has been effected by the damage, you will most likely get an error while doing so.  
I've experienced this more than a few times, actually. 
 
 
As for "what happens now?", that depends.  
 
My recommendation would be to immediately remove  the disk from the pool.  And unless you've disabled the StableBit Scanner balancer in StableBit DrivePool, that is exactly what the software will be trying to do. 
But you mention the corrupted/damaged file.... As I said, you will most likely recieve errors when trying to move the file. This includes with the balancing engine, as we actually use the same API that WIndows Explorer uses to move and copy files. 
 
So a bad file should not get moved. 
 
 
Additionally, if you remove the disk from the pool, you will need to use the "Force Damaged Disk removal" option. This skips bad files, rather than erroring out on them and stopping the removal.  Once this has completed, StableBit DrivePool runs a check on the pool, and will reduplicate files, if needed.  So if the bad file is duplicated, it will reduplicate the affected file from the other copy on the pool. 
 
 
As for for the file recovery, StableBit Scanner tries to read it multiple times, using different "head positioning profiles" to see if we can grab the file.  If it does, you'll get the whole file back.  Otherwise, it will fail, and no file. 
Whether this succeeds or fails depends heavily on the disk. 
 
 
 
As for the CHKDSK /b pass, this may or may not recover the data.  However, if the disk has any SMART errors as well, I would highly recommend RMAing the disk rather than putting it back into use.  
The unreadable sectors should not occur and indicate a serious problem. 
 
 
 
I think I've covered all of your questions, but if I didn't, or didn't cover them to your satisfaction, don't hesitate to let me know. 

Hi there,
So I think I have finally remedied (or made HomeGroups behave) the situation based on a combination of the suggestions...
 
Here's how it went, after about a month of screwing around, I think this is reproducible and Windows 8.1's Xbox Music appears to be behaving as it should be.
 
I had to un-join my HomeGroup (in all ways - via the Network and Sharing center and Dashboard Settings - check both just in case) Make temporary folders in your DrivePool ServerFolders for each share you have, move you content in each one So, create "Music_backup" etc. Move all files in your exising "Music" share to "Music_backup" Let DrivePool sit with those changes for a while Reboot Open Dashboard - see if you can remove the old shares (I couldn't remove the default shares - or any really via Dashboard) If you can't, do a "net share "Music" /delete" from a command prompt instead Delete the "Music" folder from your ServerFolders Lather, Rinse, Repeat for every folder Let DrivePool sit for a while - it needs to remove all the folders from all the duplication areas Reboot Open Dashboard You should see it has detected "Missing Folders" That's good Now, open Start Menu, type Search Change Locations Windows Searches Remove all the shared locations it can't find Apply / Close Let it sit This removes all the old entries that help you find all the content you used to have Go back to Dashboard Here's where you create a HomeGroup if you want (skip 13 otherwise) Open Settings Click HomeGroup Create HomeGroup This should finish quickly because there is nothing there... Re-create all your Shares in the default D:\ServerFolders\ locations If you made a HomeGroup, select appropriate permissions Make sure Guest has No Access I guess. Move Shares to your DrivePool location They'll be empty Shadow Copies will probably fail Go to File Manager Move your content back into your folders Click Start Type Search Change locations where Windows Searches Make sure Windows is Searching your locations (DrivePool paths) and nothing is broken If you made a HomeGroup, check your permissions Make sure your Music Library has the DrivePool Music folder After DrivePool has sat for a while with your changes Turn Duplication on for your shares via the Dashboard Open File Manager and remove your "Music_backup" folder(s) for your temporary shares They may not go away until another reboot That's what I did, and now everything seems happy.
I see some folders via HomeServer in a HomeGroup, and ALL shares via my permissions in my NETBUI server path. And all my Dashboard stuff works, and my index is correct now...
 
I had a few other issues going on - it turns out Windows Backup was filling up my drive without removing Shadow Copies.
Also, Windows Search had an invalid library location blocking it from updating my Music index, so DrivePool was having trouble rebuilding its index.
And, I seem to have some sort of "Controller Error" on a USB drive (not part of the pool) that I can't seem to track down.
The drive doesn't report any errors on the disk, so I don't know what to do about that...
 
TTFN
