[CentOS] Kernel Errors

Checking my daily logwatch file, I see the following kernel 
error:

  --------------------- Kernel Begin ------------------------

  WARNING:  Kernel Errors Present
     end_request: I/O error, dev fd0, sector ...:  1 Time(s)

  ---------------------- Kernel End -------------------------


The thing is I have not used a floppy disk for weeks.

Any ideas what's happening please?

Kind Regards,

Keith Roberts
