[mythtv-users] Recommended Disk Test

[Dick Steffens]

My MythTV box is scheduled to go into the shop on Monday because of an 
intermittent freeze. The symptom is that infrequently (once every two 
weeks or so, but not regularly) I'll either turn on the TV and get no 
response to a keyboard even though my wallpaper is there, or I'll try to 
look at a MythWeb page from another machine but won't be able to 
connect, or (this happened only once during one of the NFL games last 
Sunday) the system will freeze during a show. Recovery requires a power 
cycle. Attempts to SSH into the machine fail due to SSH being unable to 
find it.

Before I take it in to the hardware gurus I want to be sure I've run 
appropriate tests. I ran memtest with no errors. What disk test should I 
run that will be a non-destructive test? And, when I run it, do I need 
to have the backend and MySQL shut down?

Are there any other tests I can run to try to narrow down the problem?

Thanks.
