Samsung Spinpoint F1 errors

The NAS will warn you once the drive goes "DEAD". Whether you want to wait that long is up to you. You might want to try a ReSync / RAID scrubbing combo. If it passes both those tests, and the NAS doesn't warn you of problems with the drive, ignore it for now.

I've seen that sometimes SMART can be a cause for paranoia rather than being helpful. It's not designed for interpretation by the user, but by the host system, and different manufacturers seem to use it / implement it in different ways.

The other option is to put it in a removable USB caddy, and attach that to your Mac and find some test software that will run a scan on it.

Hi,

I will continue to wing it. I have a solid backup, and when the drive finally fails I will replace it with another. The errors keep increasing everytime the NAS scrubbs it, so there is probably something wrong.

I like to have one spare of each drive size I use on hand. Then I can replace the drive w/o delay when it fails. Backups are essential of course, but restoring them can take a while - I'd rather keep the array working if possible.

I replaced the drive as the count of "Reported Uncorrect" was up to 26. Right now the NAS is doing a Resync. I had a spare in an enclousure which I use for extra BU, and I will just continue to use it for this.

While most of us like to have a "matched set", it is not really necessary. In fact at one point on my NV+ since it had been going so long, I had four drives of two different manufacturers and two different sizes. I started with a matched pair of Seagate 500GB and then added a Samsung 500GB (it rejected the second as too small) so the last drive was a Seagate 750GB (of course treated as a 500GB). It ran like that without problems for about six months until the increasing size of the array necessitated an upgrade to 1TB drives (back to a matched set). Any drive on the HCL should work without a problem.

I don't run a matched set in my Pro, and have no plans to change that.

It is less important in X-Raid2 to have all the same size because of the layered array. With the prices of drives today it is more likely to purchase a few drives and then add to the array as needed. Usually by that time the original models are no longer available. And the array doesn't care as long as the drives work with the controller.
