One of my disks is starting "making funny noises", so I expect
it to die rather soonish -- however, it does not seem to say so,
there are not error messages from the SCSI subsystem.

  I assume this is because the disk factory defaults to the Windows
way of "keep quiet, reassign block automatically, do tons of retries"
as not to worry Joe Average User and keep the tech support people
happy.

  Is there any tool to tweak the drive's appropriate mode page bits to
make a disk report errors immediately?
