2 seconds later, I get "the verify disk command for disk disk3, SoftRAID ID: 06DFBA1F786F5680, SATA bus 0, id 2 (Thunderbolt) completed successfully."

See attached screen snags.  I assume the drive is bad at this point, I have a new one on the way and will try it in next day or two, but if you can explain those two messages I'm all ears.]]></content:encoded>

"Softraid Driver:  The volume 'Backup Volume1' (disk6) failed to validate because one the disks encountered a read error. The disk (disk3, Softraid ID: 06DFBA1F786F5680) was unable to read sectors (offset 1520938516480, i/o block size 8338608, error E00002C0). The disk should be replaced."

Seems like I need to replace the drive. Does that make sense? or could I be getting a false error message?]]></content:encoded>

                        <content:encoded><![CDATA[This Lacie 2-Big enclosure, running RAID 0, has been working fine for years, more recently on a 2017 iMac.  I moved the drive to an older Mac Mini (2012 server model) last week. The Lacie is a Thunderbolt 2 model , one of the earlier ones.  It had been up and running fine for about 4 days on the Mini when the issue occurred.

Today, I was running a backup job from another Mac to the Lacie drive attached to the Mini and it suddenly ejected (see below) with an "error (E00002E4)".   Can you tell me what that means?  

(Note: I powered off the drive, powered it backup restarted the backup job, and all completed normally and the drive seems normal).
