No, in fact it is a VERY good thing that the driver is doing!
Enabling write caching allows a hard disk or other fixed storage volume to
signal a sucessful write and to store the data in a RAM cache as opposed to
writing it out onto the actual disk media. This does boost performance and
is a great theory, but bad things happen if a machine goes down or the disk
drive chokes when writing the data to the actual disk. Basically, the
failure tears a gaping hole in the file system...which will usually
obliterate quite a few files depending upon how much was in the write cache
at the point of failure.
I always turn it off on my systems...the risk isn't worth it.
