Tons of Event ID 153 for my DrivePool drive

[fly]

I'm see a TON (possibly hundreds per day) of Disk Warnings like the following:

 

The IO operation at logical block address 0x11 for Disk 13 (PDO name: \Device\00000051) was retried.

in my event log.  I've seen a previous thread that says they're normal.  However, I've never seen a single one until I recently added an SSD and moved to the SSD balancer.  Any ideas?

This is normal. 

Something is trying to query a sector on the drive. But .... there are no sectors on the drive.  So it generates an error.

But make sure that the pool is disk 13.  If it's not, then it's a different drive.

It's absolutely the pool disk.  Any ideas why this never showed up until recently (and in the hundreds)?

Honestly, no.  It may be software that was installed, a Windows Update, or something else.

Either way, the error is harmless and can be safely ignored.
