I had a 5 drive FreeNAS 11.0 and lost one drive. I detached the volume and now I can only see 4 HD. Can I recover the data.

I think I setup my volume to maximize storage and no hot spare. I had errors on a drive and detached the volume. The failed drive is not seen on boot up and only the other 4 drives are seen. When I try to do zpool import I get the error a drive is missing. I have tried everything to make the drive available but no good. Is there anyway to recover the data with only 4 drives? Any commands would be appreciated and I can get data from zfs or zpool or etc. needed.

That looks all kinds of wrong. You had, perhaps at different times, two different pools, both called FreeNAS. The first was set up with three disks in RAIDZ1--you could import this with one disk missing, but not two. The second was set up with more than four disks striped--you'd need to be able to have all those disks online at the same time to be able to import the pool.

Since I am new to NAS, I originally setup my NAS with 3 disks, but added 2 more larger disk and upgraded to 11.x so that is why there are two pools. When I upgraded it setup the new pool. My problem is the missing disk will not boot nor will the OS show it. When I connect it anything on the SATA bus will not be seen on the OS. Something wrong with that disk. I am trying to get the data off the other disks if possible.

What I am looking for a way to recover the data with the 4 remaining drives if possible, or find out what drive is missing (I think I know, but not sure) and get it working. Right now the drive I think I need is not usable on the bus and when connected any other drive on the bus disappears. Ideally I would like to import the volume somehow and then make it a Raid5 or with a HotSpare.

When you have a striped pool (as the second "FreeNAS" pool was), you must have all disks available. When any single disk fails, all your data is lost.
