Having an issue lately with stores / drives going invallid randomly.
Drive will format fine under windows etc just fine, but fails under RouterOS..
(Were fine for a few days then the stores would go invallid, then the drive would change USB ids..) then would not mount.
I have thiese same drives (in sata mode / with out the sata to USB) on an i386 and they are fine… (ROS 3.26)
