I've never seen or heard of this before but it happened to me today. I had some Seagate 3TB (St3000dm001) laying around that I used for an extra backup before I reconfigured one of my pools. To do this I pulled out a pool that I wasn't going to use and replaced it with these 6 Seagates. After configuring them as a Raid Z2 volume I proceeded to copy the data over. It took over 7 hours for what should have been a 90 minute job.
I did notice that on 2 of them the drive indicators were staying on for long periods of time and decided to check them after the copy finished. A quick check on Crystal Disk showed no problem for either of them.
That left me a bit confused and while I sat there staring at the screen it hit me....NCQ was grayed out. I took
that drive out and checked the 1st one and same thing. I then checked the other dozen of this same drive I have and every one had NCQ. Somehow my problem drives lost it.
Anybody ever run into this before and do you have any idea what might have caused it?
