Hello, well, the aim of my post sounds strange, but I'm serious. Background: I run at home a 14-CURRENT based server with a ZFS volume (RAIDZ) comprised from 4x 4 TB HDD. A couple of days I had to exchange the HGST NAS drives since one got a permanent SMART error. So all HDDs have been replaced by now with four times Seagte IronWolfe Pro 4TB drives. So far, so good. Now I face a weird sound sourcing at one of the new HDDs. The box is supposed to be a heavy duty poudriere build facility, so the drives are up 24/7. It seems that one (or even more) drives emitt a weird sound like the spindle motor is loosing for a fraction of a second power and spiining up the the drive again. Searching the net reveals that at least one Seagate customer did have the same issue and he provided an audio file of that very weird sound, to be found here: Post at reddit: https://www.reddit.com/r/techsupport/comments/sca6al/seagate_ironwolf_pro_making_weird_noise/ and herin the post of the audio file: https://www.mediafire.com/file/x3le816qsakiff9/Hdd.mp4/file I checked S.M.A.R.T for any unusual data, but everything is fine. The values for Power_Cycle_Count Power-Off_Retract_Count Start_Stop_Count seem all within a reasonable range compared to the life time in hours (did some simple statistsics ), nothing looks unusual. Also, the advanced view onto each drive via smartctl -x doesn't give me any hint of a power failure as a source for the noise. So, big question here is: the drives are attached to a HBA, LSI3008 based SAS9300-8i. Is it possible to retrieve via CAM more health paramteres than those gathered by SMART/smartmontools and if the answer is yes, how can this be achieved? It close to impossible to isolate the drive making the noise. My guts tell me to RMA the supposed to be faulty drive and not to wait until it dies from "spindle motor desease" or something that is the source for the noises. Thanks in advance, oh -- O. Hartmann
