I think the speed issue might be that external enclosure I used. I've got two of those I think. The other external enclosures work at full speed tho. They a lot newer model. The thing I like about the one I used, I just open a door, slide the drive in, close the door and it's ready to go. My newer type enclosures require me to disassemble them to put the drive in. They are nice enclosures when you plan to leave a drive in them for a while. The concern I have mostly is the slow part when hooked to the NAS mobo directly. I have a good size power supply for that old thing. It likely runs at about a 20% load most of the time. The most excitement it sees is when I do OS updates and backup updates at the same time. LOL I included that first error just in case it may be relevant to the one from the NAS box about being slow. When I did some searches for that error, I never found a real answer to the question. Is that normal for some drives or a sign of future failure? It's a 20TB Seagate EXOS Enterprise drive. Maybe it has a extra platter which takes longer to spin up or something and it is normal. Then again, maybe it is a weak motor that is about to fail. Some stuff I found claimed it was a kernel error. I've never seen that on either of my systems and I been using those same kernels for a long time. As most know, I have quite a few large drives here. o_O As far as I know, all my rigs are SATA 3 ready. Dale :-) :-)
