If the device is a SoftRAID/FakeRAID then first activate it and mount a different device under the /dev/mapper/ directory, (e.g. /dev/mapper/nvidia_eahaabcc1). Observation 7: Disk replacement counts exhibit significant levels of autocorrelation. For example… Size: 40MB Result: The system detected the drive fine, but won't mount due to a LBA (logical block addressing) issue caused by to the newer enclosure (i.e. A completely dead drive, on the other hand, could be due to a faulty printed circuit board (PCB), which would be external damage.
