I have an elderly computer running win 98SE it was short on memory and only had a 10 Gig HD. I have put in an extra 250 meg of Ram and an extra 10 gig hard dis as a slave.All ok. But I have a 20 gig Hard disk that I want to put in in place of the 10 gig slave. I set the jumper to slave and fitted it into the computer. It is recognised as a slave but is not showing up in My Computer?? Can someone please tell me why this is and how to correct this. I want to reformat it to get rid of the data before I give the machine to a local youth group.Thanks for any help.
