I have a pair of WDC WD40NMZW-11GX6S1(4TB My Passport USB 3.0) drives. I purchased them so I could attach them to my home Linux server. The drives randomly flake out and ‘disappear’ from USB. I tried them on another Linux host(moved from Intel to Raspberry Pi 4) and the same thing. Tried putting them each on their own dedicated AND powered USB hub to no effect.
I have run the WD utilities on them when I attached them to my Mac. They both are current on firmware and pass the diagnostic tests. One of the drives(can be either one) will go casters up sometime within the syncing of the hard drives as a RAID1 mirror. I have been a 25+ year Linux user and I have used Software RAID both MDADM and BTRFS raids. From what I see, this isn’t a software problem and this isn’t a host problem. I’ve tried different releases of Linux and my other non-passport arrays work(getting old hence the flip).
Anyways, what is truly odd is that the drives just disappear. When the drive goes south, ‘lsusb’ no longer shows one of the two USB drives. In fact, to get the drive back up, I had to unplug it and plug it back in.
Thoughts/ideas/sugestions?
Below is some debugging info with comments:
