I have an Dell r720xd with various drives including other sas/sata drives using a flashed raid controller. Seemingly the server was reset and now is facing an issue where the device won't spin up. I tried putting the drive in a bay which is known to work and still won't power on. I have used the drive in a hard drive dock and it works normal. It seems as if the server is not issuing a start up command to the drive through the sata interface or something. The only thing I can think that I did recently was enable to drive to go to sleep using hdparm -y /dev/sdX. However based on what I read, this does not last through restarts so it shouldn't be affecting anything. I tried covering the 3.3v pin if somehow that became an issue after a device reset but it did not change anything either (not that I expected it would).
