sorry yeah not much info on the first post - well what i was thinking was running hal in C hard drive and brain on an external hardrive that way can have more space so hal can learn more information or can you even spilt the brain memory between and external hard drive and c/d drive reason i ask is because i have 70gb free on Cdrive 74gb on Ddrive and have an external hard drive with 2TB so would prefer to use that if i could? it all depends on how much space hal requires i suppose i imagen it is quite a lot to learn and store information?Cheers Andy
