9.1 Troubleshooting

The Diamond-VT provides a number of indicators to identify the operational status of the array. System status and error information is readily available. If your situation is not defined here or elsewhere in the manual, if these solutions do not help, or if you have any questions or concerns about any aspect of operating the Diamond-VT, contact technical support.

Windows 2000 special instructions

When using Windows 2000 and booting up the Diamond-VT for the first time, the New Hardware screen may ask for a driver. While a driver is not necessary, install a dummy driver to eliminate the screen’s appearance. Download AttoDM2k.zip from www.attotech.com, unzip it, and install the driver according to the instructions in AttoDM2k.pdf.
