Spurious SMART error messages

I have a Series2 hacked using the Zipper. Every day, I get an error message when arriving at 'Now Playing' that says there are SMART error messages in the kernel log file. The details of the supposed error messages have them all occurring on the first day I installed the drive. (it's a new Western Digital 500 GB AV-GP SATA A/V drive)

Testing the drive with smartctl gives no errors, reports a healthy drive.

I attempted to clear the kernel log file by deleting /var/log/kernel and then restarting the DTiVo. Looking at /var/log/kernel in VI shows no such messages.

I'm still seeing the error messages.

Is there someplace else that I need to clean the log messages out of?

Thank you,
