Is there a way to disable the write cache on my CF via registry or
scripting?

Thanks a lot.

The actual paramter is based on the drive ID. here is an example of the
registery key:

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\IDE\DiskVirtual_HD______________________________1._1____\5&35dc7040&0&0.0.0\Device
Parameters\Disk]
"UserWriteCacheSetting"=dword:00000000

You fist have to find the ID for the disk and then use it to turn off disk
cache.

Or you can use the dskcache tool from Microsoft see

I have got a written statement from Microsoft that the Eula is wrong and you
are allowed to use it with Win XP.
