Hi Tracy, Jim, and Neil

Thanks for the replies and pointers. I will investigate these further. Much appreciated.




>Do you have a raid controller by any chance? Some controllers prevent access to this feature unless the controller has a battery. On some controllers, it can be changed in bios but not in storage management settings. It can also be dependent on the hard drive SCSI? IDE?

>>I have two boxes with the same hdd, drivers, and controllers, same Windows, etc. On the one I have the option to enable/disable write behind cache under the hardware properties tab - disk drives node. On the other machine this option is not selectable, it is greyed out, and the check box appears to not be selected. Why can I access the check box on the one machine but not on the other when to all intents and purposes these are identical machines.
