Ok, an update. Writing with bs=512 had issues, as it was failing on a
read, and reallocating was failing. I think this is because the
physical sector size is 4096b, and it needs to read the other 7 512b
logical sectors if it wants to write just 1 512b logical sector. So,
I ran:
sudo dd if=/dev/zero of=/dev/sda seek=732230414 count=1 bs=4096
This seems to have worked. In syslog, I just now saw:
Jan 4 12:12:07 machinename smartd[2203]: Device: /dev/sda [SAT], No
more Currently unreadable (pending) sectors, warning condition reset
after 90 emails
Jan 4 12:12:07 machinename smartd[2203]: Device: /dev/sda [SAT], No
more Offline uncorrectable sectors, warning condition reset after 90
emails
Jan 4 12:12:07 machinename smartd[2203]: Device: /dev/sda [SAT],
SMART Prefailure Attribute: 1 Raw_Read_Error_Rate changed from 113 to 117
I'm now running a checkarray and will report back final results, and
whether the SMART warnings return. Thanks all for the help, hope this
marks the end of this issues...

Damn. I saw your initial mail, but I was out and nowhere near a device I
could use to reply sensibly.
You should *really* check by looking at the mdadm --examine output and
calculating the position of the sectors in question to be absolutely
sure the area you just wrote over was not in the active array area. If
it was then you should stop the checkarray *now* and come back for advice.
Sorry I don't have time right now to elaborate.
