File/Hard Drive errors

[keithclark at k-wbookworm.com]

I seem to be having an issue that has started showing symptoms in
Evolution.  Starting this morning, Evolution shows no incoming emails.
It says it is downloading them via a pop server and no errors show up,
just no emails either.  I can access that email account with a web based
email client and I am getting new emails.  They are even marked as read,
so I'm sure that Evolution is downloading them properly.

Also, when I tried to reboot, it took forever and the only way to
actually get it to boot, was to press esc.  I think it might be doing a
hard drive scan, but I cannot tell.   My monitor just goes blank at
startup.

I'm not sure where to go from here.  Is the a way to check my hard drive
from the command line?
