Correct, first validation.

Thank you.]]></content:encoded>

                        <content:encoded><![CDATA[Good Evening:

I have an 18tb volume (part of 6x4tb RAID 5 array with 3 total volumes).

Yesterday, I/O errors popped up on one of the disks and Time Machine would fail to complete on my "BKPvolume".    I cleared the I/O counter and tried again.  No I/O errors and it passes smart.  That said, it is a repurposed disk from a home NAS that has 28000+ hrs of service, and other repurposed disks from the NAS have failed in service.

I have already purchased a new 4tb and it should be here Monday.  In preparation I copied the volume that I was concerned (MEDIA - 1.4/18TB used) to another 8tb drive.

I am in the process of validating the volume - and less than a third of the way through, 230,000,000+ blocks have been updated.

While I know on a first validation of a multi-volume RAID 5 array some blocks may get updated, this seems like a lot.

TL,DR:  should I be concerned about the data integrity of the volume?  

The copied data (a block for block copy) is backed up and safe.  (The other 2 volumes are 1tb time machines for MBP and Mini - - but I CCC they every three days so not concerned if they get nuked).]]></content:encoded>
