Error Message Interpretation Please: FN8.0.1 B4

I just booted up my server after moving my home office down the hall:
ata2: timeout waiting for write DRQ
ata3: timeout waiting for write DRQ

zfs status shows all drives on-line. I am 6% into a scrub.

I have 10 x 2TB drives in a Z2 configuration. Dual core cpu with 4GB ram

Have you tried using Google? Seems like there are quite a few people with a similar issue.
Also, without knowing your hardware, not much more can be said.

Thanks. My main question now is: "Is my data safe?"

 

[billm]

It's never safe if a computer or a human is involved.

switched from sata to ahci mode in bios without change. I did not get this error message before upgrading to 8.0.1 B4 from B2.
