Do i have to worry ?

I also got this error, but from my perfectly working hard-disk. I use
a VIA motherboard (7DXR) with a seagate 160Mb hard disk with 8Mb
cache. Now, this hard disk has cached writes facility, which caused
the kernel to show this message and even make hard disk useless until 
I rebooted the system.

The remedy I found was to disable the cached writes by using hdparm -W0.
