With messages like this should I probably just not use this disk in my array?  I have 3 of these from old work computers and just curious if I am just begging for trouble. 

Don't use those. You'd need them too read 100% correctly to rebuild the array, should you ever need to. There's a reason why it's a Pre-Fail notice lol, it's failing.

Sorta what I thought guess ill pull and throw them out

 

You could try an extended test and see if it passes 

I did preclear them  yesterday and they seemed to pass that test is what you are suggesting something else?

No, it's under the SMART stats for the drive.  It will test the entire drive and if it can read the entire drive successfully then it will report PASS, otherwise it will report a failure and you'll know to toss it.

But it will take a long time to complete (several hours)

So if i do take them out it looks like they have all had some amount of data written to them how do I move that to the other drives so i can pull these safely?

I like the unbalance plugin. it lets you move data from one drive to another

After emptying the drives, you will have to New Config without them and rebuild parity.

 

I don't recommend using older and/or smaller disks in the array just because you happen to have them. Each additional disk is an additional point of failure, requires more ports, more power, and at some point, more Unraid license. All bits of all disks must be reliably read to reliably rebuild a missing disk. Older and/or smaller disks don't perform as well as larger newer disks. Add drives when you need additional capacity, not just because you have some disks laying around.
