HD Errors

[Robert McIntosh]

OK,

It's a Maxtor DiamondMax Plus 9 120GB ATA/133 hard drive (EIDE).  It's 
in a Dell Dimension P133v.  I also have a Dell Optiplex GX1 which only 
supports a hard drive of 80 GB max.  This machine is at least as old as 
the optiplex, so it's likely to support at most 80 GB as well, not 120 GB.

I ran Maxtor's HD Diagnostic tools on the drive and the test, with the 
exception of the long, full test, came back as "passed".  So, I have 
reasonable confidence that the problem isn't the drive.

FreeBSD says during drive formatting that there may be weird errors for 
drives misreporting size.  Are the errors that I'm seeing likely 
reflective of this?  What should my concern level be?

Thanks again,
Robert
