I recently bought 5 WD Red 10TB drives. Occasionally the drive(s) makes a strange sound, I’m not 100% sure it’s the 10TB drive(s), I have 3 WD Red 4TB drives too and they are right next to the other drives in my Synology (8 slots) NAS. Therefore it’s hard to pinpoint exactly which drive or drives that the sound is coming from. The sound can suddenly disappear and reappear many hours later, it seem to be pretty random. As I’m writing this the sound is gone again, but I managed to make a short recording of the sound.
Listen to it here. The first thing you hear is the sound in question, and it repeats during the recording.
I have never heard this sound before, I have owned a lot of WD drives over the past 20 years but none have made this sound to my knowledge, so I need help to identify it. Is it a normal sound(for the helium filled drives) or is there something wrong with the drive(s).
The S.M.A.R.T data does not indicate there is any problems with the drives and everything is working just fine.
Thanks for all the help
