New Toshiba HD for Z1 in April 2008

[mike35z]

Some of the people that are selling the Z1 upadate Hard drives are not using an automotive grade drive. The original HD used in the Z1 was built to higher specifictions. One of the specifications is the ability to run correctly in wide variences of temperature. The interior of a car or truck can often reach in excess of 130 degrees in summer and below zero temps in the winter. The hard drive is the main mechanical device used in the Z1 units. This places rigid specifications on the hard drive. The toshiba OEM drive was built for these tolerances. I have noticed that most of the Ebay replacmemnt drives are not a Toshiba automotive grade hd. Toshiba sells a 40 GB automotive hard drive that spins at 4200 rpm. MK4050GAC. The drives listed on ebay state they are 40 gb, and spin at 5200 or higher. These are not automotive grade drives manufactured by Toshiba. The Automotive hard drives are also about double in cost. The cheapest Tosheba 40gb hd, that is automotive specification, costs around 129 dollars or higher. The ebay replacment drives are standard laptop type hard drives, and will not perform the same as an automotive grade drive. I would suspect that is why your HD is not booting correctly. What can also happen is that these standard hard drives can become damaged from any rough vibration, especially during bootup, or in extreme

temperature conditions. When the hard drive is first turned on, it reads files for booting up the system. If any of these files become damaged, booting can be delayed or not boot at all. If your going to replace the hard drive, be certian it is an automotive grade drive.
