While linux has support for write barriers (that allow you to run safely
with the write cache enabled), it needs support from the drive.
I would suggest that you should run with the write cache disabled unless
you can verify working barrier support.
The fact that your drive reports IO errors is also worrying - you might
just have a bad drive... You can look at drive help with tools like
smartctl.
Good luck,
ric
