Now I discover it seems to be due to a strange windows 7 prof'l behaviour of my partable, that in some cases doesn't take settings and bahaves just like a totem it doesn't takes windows update settings and others, but others yes , so it seems to compress drive G:, but it doesn't, otherwise on my home netbook it really compresses.
