These instructions deal with settings that will affect the performance of your machines. Although these are standard procedures and should not require an expert to perform them, you should have a fair amount of experience with computers before attempting to configure any of the settings described here.
There are issues with using write-behind caching on .tps files (.tps files are the files that store your data and configurations in CompuChem applications, i.e.: our file system) that can cause file corruption and/or data loss.
To avoid this please switch off write-behind caching on all workstations that access our programs, do this by following these steps:
On Windows© 98 machines:
- Select: Start > Control Panel > System > Performance > File System. On the Hard Disk tab locate the slider that controls Read ahead optimisation and slide it all the way to the left:
notice that the text under the slider changes with each measure you slide it back.
- Select the Troubleshooting tab and tick the option: Disable write behind caching for all drives.
- Accept all changes by clicking Ok twice, then restart your computer to initialise the new settings.
On Windows© 2000 machines:
- Right Click My Computer, select Properties > Device Manager
- For each hard drive right click and select Properties, on the Drive Settings tab clear the tick out of the box labeled: 'Write behind cache enabled'.
On Windows© XP machines:
- Right Click My Computer, select Properties
- Select the Hardware tab and click the Device Manager button
- For each hard drive right click and select Properties, on the Policies tab clear the tick out of the box labeled: 'Enable write caching on the disk'.
Another important step to take is to exclude files of type: *.tps from any anti virus software that may be running on your system/network.
