Hi,

My drive became completely inaccessible for a long time after your
suggestion so I couldn't try it.

I just tried it and there is no Optimize for Performance (I'm running XP
SP2) but there is a check box saying Enable Write Caching -- but it's already
unchecked. The drive seems to work now, I moved it from SATA 4 to SATA 5.
Guess I'll have to keep playing around with it......

Thanks again, and any other suggestions welcome (until this Newsgroup closes
:( )
