It wasn't several days, but it was multiple passes. I'd have to look 
back through e-mails to see if I noted how many.

Thanks for recommending smartctl. I ran it with the -H option to verify 
it's there. The results of that are:

rsteff at ThinkCentre-M58p:~$ sudo smartctl -H /dev/sda
[sudo] password for rsteff:
smartctl 5.41 2011-06-09 r3365 [x86_64-linux-3.5.0-18-generic] (local build)

=== START OF READ SMART DATA SECTION ===
SMART overall-health self-assessment test result: PASSED


Is this a completely non-destructive tool? From what I've read it 
appears to be, but I have a number of recordings I would like not to 
lose, so I'd like confirmation that running smartctl --all /dev/sda is 
non-destructive before I start. Also, this is a 500GB drive. If smartctl 
is running will it interfere with recording later this evening, or with 
playback this evening (6 or 7 hours from now)?

Thanks.

BTW, if it matters, this is a stock Ubuntu 12.04 system running version 
27 mumble-mumble of MythTV. (Is there a way to determine the version of 
MythTV from a remote machine, either with MythWeb or by SSH login, or 
some other method?)
