Hello community. I am trying to set up a RAID to backup some data I need another copy of, so I reached for an (old, loud) 4-bay USB case I had, which had *four* different WesternDigital WD Blue drives at 6 tb. For some reason none of the disks would mount or be recognized by my Mac or PC. They seemed to be spinning (they were vibrating, or seemed to be), but nothing would cause them to be recognized. So I bought a new enclosure but they performed the same, with all six disks refusing to mount (despite the fact hat I've used these for RAID backups in the past).
I took a spare Seagate and put it in my old enclosure and it worked perfectly. Is there any reason why WE Blue disks could all fail in a way that caused them to not even be seen by the OS? I read something about pin 3 needing to be disabled from certain WesternDigital drives to work in USB and applied tape over that pin (and the two to the left of pin 3), but it made no difference.
Having trouble understanding why all four WD Blue drives of the same period and not even that old (all are Made in Thailand 2019 or 2020) could refuse to mount or be seen by any USB enclosure, including my ancient don't from 8+ years ago, as well as a brand new one.
