Ok, I've been more than 24 hours testing the disk with the LAN cable disconnected.
And nothing has changed. The disk is doing spin up and spin down constantly.
So... we must conclude that the guilty of this situation is the SMART function of the disk?
I only have clear that spin up and spin down again and again, several times by hour, is not a good behavior for the disk health.
So, what option do you think is better?
1. Always spining disabling the "spin down during inactivity period"?
2. Or getting that the disk remain still until there are access to the data on the disk by disabling SMART function.
I don't know how to do any of these options (I think it can't be done using fvdw-sl firmware interface), but I think I need to do something to prevent the disk failure due to spin up and down constantly.
