Drive Temperature

I just got home after spending a weekend out of town. I checked the status of EX2100 and discovered that drive 2 temperature was at 29C, but drive one was at 37C. I do have the drive sleep option set to on.

Any idea why drive one’s temp would be so much higher?

Seems to me you are overly concerned.  37C = 98.6F, ( human body temp) so your 2100 doesn’t have a fever. Mine don’t always match either; like first thing this morning they were not matched by at least 6 degrees.  Right now, after streaming music for over an hour they both read 33C degrees.which = 91.4F, My System Temp says “Normal”.
