Is this "short while" in the middle of an active session, or have you suspended/hibernated/rebooted/powered-down, in the meantime? You may need to look into your power-management settings, and make sure that any wake-up/thaw events reprogram the setting. I had to do that with mine. > More importantly, the next time I try to disable it,it says its > disabled, but the drive carries on clicking, and the Load_Cycle_Count > still keeps going up. Try a different value, such as 254, instead. -- [tim@localhost ~]$ uname -rsvp Linux 4.13.16-202.fc26.x86_64 #1 SMP Thu Nov 30 15:39:32 UTC 2017 x86_64 Boilerplate: All mail to my mailbox is automatically deleted.
