i don't think the problem can be fixed through hdparm -B 255,
because hdparm -B 255 fix the the famous load cycle problem.
but the problem on my computer it only happen one time at every system boot up.
btw i found the nexenta core platform 1.01 also has this problem on my computer?
but solaris 10 use ufs file system don't have this problem,<B>so I think it
may be the kernel problem or the zfs file system's problem</B>.
becasue half years ago I install solaris 10 update 4 ,it don't have this problem
