A bit of a preface. I was just recently running OpenElec, but tried to do an upgrade. I ended up having to do a clean install and while doing so I added a new internal drive into the mix via a SATA 2 port adapter. So I have 4 data drives in total, 3 currently recognized, along with a SSD for my OS and temp download area.
So my first concern was that LibreElec was just not recognizing it via the expansion card. So I took two data drives out, and had the same experience. I put the drives back in, and compared a dmesg | paste of the events and at least it is initially seeing it in both instances. So right now I have all 4 drives back into play.
The drive in question is a "WD60EFRX-68L" which I formatted as ext4 on a windows machine.

Results of dmesg | paste: http://ix.io/1sf5
When I took some other drives out so this new drive would be on the board's controller I got this result: http://ix.io/1sf2
Given it was formatted ext4, and I ejected the disk, it should have been clean.
Any thoughts?
