If you've been following my posts, I'm new to unRAID. I don't have it installed yet even, but I am going through the process of preclearing all of my drives on my newest server.
I have 24 HDD's that I'm going through the preclear process and am on my 3rd batch of 6. I can only run 6 drives at a time as my multiple controller cards are not recognized by version 4.7. And I'm not interested in testing out the development series yet. I will wait until I have run through all my preclear checks.
I am running each drive 6 times through preclear, as I do not want to worry much about having a failure. It takes a lot of time to recover from one, and I currently have one of my servers sitting around waiting until I have time to correct/replace one of it's faulty drives. It takes a lot to get into my servers as they are all crammed into a storage closet, at the very back. I have to move full shelving units and my deep freezer out of the way to wheel out the server rack.....then disconnect LOADS of cables. The last time I took it out of the storage room, I took some photos. Attached is one to show you what I'm talking about.
I'm not sure what to look for in the results, so I'm posting one of them here. I tried to post 6 in this thread (1 batch), but it exceeded the maximum allowed characters by more than 4 times!!! So if someone could point out which areas to look at, and what types of numbers to watch out for it would be greatly appreciated.
