Up to now I haven't noticed any degradation of performance on my desktop. If this remains the case then I'll make the change permanent otherwise it seems the risk of data loss are small, at least in my case. So if things slow down I'll re-enable the write-caching. Are there any particular tasks that would make the presence or absence of write-caching? Cheers for your advice, Jonathan
