    Hi

    I have the above DVD recorder and really like it, apart from 1 thing.

    When you power off is it meant to take about a minute for it to turn off? Also it makes a grinding kind of noise when it is powering down.

    Is this meant to be there?

    Exactly the same here, can't say it's ever worried me.

    I just assume it's the hard drive shutting down ala a pc. It has a similar noise anyway??

    Hi

    Yes just the hard-drive powering down. The recorder does a bit of frantic house keeping before it goes off, and then shuts down. In order that hard-drives stop spinning as soon as possible (in case they are moved) a break is applied by telling the hard-drive motor to go back the opposite way (similar to a reverse thrust you get when a jet plane lands), it is this noise you are likely hearing as the motor coils try to reverse spin the hard-disc, the noise is due to the fighting opposing magnetic fields and quick deceleration.

    If the hard-drive was spinning and you "cut the power" (do not do this though) the hard drive would not make any noise as no reverse thrust can be applied as there is no power, it would then take a minute or so for the drive to come to a stop by itself, and during that time it is susceptible to damage if moved, hence the breaking of the drive where possible.

    The Pioneer recorders contain S.M.A.R.T. sensing, this means the drive will report any problems to the recorder and you would see an error message if anything was wrong with the hard-drive.

    Regards

    Phil

    We have a 530 at work and sometimes it just fails to finalize a DVD-R burned with high-speed copying from HDD (gets stuck on the menu creation) so I sometimes have to "cut the power" which is followed by a slow startup...but it is also a bit slow to start-up normally, and shutting down is alos a "long" wait...but this machine is sweet...
