So here is my story. My pool was down to about 3TB of free space so I shucked a new 12TB drive and added it to the pool via USB while I wait on new hardware to add it to my case. DrivePool was taking so long to transfer and according to Scanner capping out around 20MB/s. I impatiently figured if I remove one of my smaller 6TB drives that have errors on them and only duplicate files that I could put this new drive in it's place and maybe get a faster transfer so I could add this new drive to the pool. I realized the shucked drive needs a molex to sata power adapter in order to be added to my computer (thanks WD!) which at the moment I did not have. Plugged the original drive back in, possibly swapped SATA cables with another drive, maybe the 10TB that you see with "other" files.
When I booted back up my pool stated it was missing 2 drives, my 6TB I pulled/reinstalled and for some reason one of my 10TB drives. All drives were disconnected when I attempted to install the new drive to the drive cage. These 2 drives showed up underneath Non-Pooled instead. Again, I impatiently removed the 2 "missing" drives from drive pool and added them from the Non-Pooled section and foolishly assumed DrivePool would see their contents and know what was what. I was wrong, now the 2 drives only show up with 100% "other" content. These drives are nearly at max capacity with data I need that should be part of my only pool as drive Z!
Any help much appreciated! Screenshots attached below, why such slow speeds? I have the priority increased in DP.
