Hi Mark

it is possible to use and external usb drive to try a test?

i were reading lot of documentats (if i am not wrong , also some official FB papers) where is specified to do not use for DB integrity in case of "disaster" any write cache options

for now , on the server , obviusly , both disk have disabled that option

just wondering wich server that is used only for DB pourposes does it , to have write cache enabled
