A couple questions about spinup/spindown

[Hastor]

Just curious about a couple things:

- If I hover around the HDD temps and click when the cursor is a ? for more info, it says that temperatures won't be read for spun down drives, and a * will be shown instead. I just noticed that. For a couple years now, I've heard my drives spin up and down, but always seen a temp, never a * show up. My drives ARE spinning down right?
- If I click 'spin down all drives' or 'spin up all drives', how long is that for? If a drive is in use, or a file from it is requested, I'd assume it would spin up. Does spinning up just spin down after the normal idle time before a spin down?

 

Thanks, just wanna be sure I understand what some buttons do, and that my drives are spinning up/down properly.

From my experience ( SATA disk ), only * means it spin down.

Just few second.

Yes in most case, but exclude in some case, .i.e. SMART extend test, it will spin own too and cause extend test abort.

Timer just for spin down.

All of my disks are SATA, I even hear (and wait) for them to spin up, but I have never seen a * for the temperature. They always maintain a temp a few degrees above room temp for ones in external enclosure (28c in a 24c room), and the ones in the server tower a couple degrees more. Even if I haven't accessed them for days. Even if I click spin down, I never see a * - is something wrong? Sharing my config. All my drives are Seagate, either Ironwolf or Exos.

You have diskspin down disabled. look at settings -> disk

[Hastor]

Ah, you're correct. I don't think I ever touched that setting, is it default to never spindown? I know when I haven't used it for a while, I typically hear more noise, and have to wait a second before it becomes responsive, same when accessing a file from a different disk on the array, so it always seemed like a spindown delay was there, but I'd never seen the * as the temp.
