[lug] SD write timeouts, drive appears to be fine

Nobody said badblocks, so I will. I've used it to cure and kill flaky drives.
I would absolutely try it in the current situation, after pulling a backup (files or image, whichever's appropriate) to known good storage.

IMHO, for a drive that's approaching 8 years of power on and starting to possibly show errors - probably time to consider replacing it. At least make sure that you're not relying on it for anything too important. Drives are inexpensive enough that it's cheap insurance.
That said, If you can't be certain it's the drive, I'd explore the controller. Maybe move it to another port or try a different controller all together.

I'm getting some HD write errors in kern.log. At the time of the errors,
the only thing running is rdiff-backup, which writes to the drive in
question. rdiff-backup reports 0 errors on multiple backup runs.
I tried using the find -inum command to locate the file where the write
error is occurring, but it finds no such file. Multiple messages have the
same inode number.
The drive is a Hitachi Deskstar, with a lifetime of 63594 hours. I ran a
SMART extended self-test, and the drive passes that, with no attributes
even close the thresholds.
Here's the sort of messages I'm seeing.

I've tried some web searches, an and not found anything more suggestive
than possibly bad cabling, though that seemed to be pointed more at USB3,
and file corruption.
Any suggestions for pinpointing what's causing the problem? I'll probably
run fsck on it later on Saturday or Sunday.
