I am trying to add my old 10 gig hd to my new used computer. The new comp has a 15 gig hd. I would ultimately like to have both but for now need some programs from old hd and data. I have no instructions or disks for either hd. The comp is a compaq deskpro en p866 pent 3 128 ram with win 98 se. my old hd has wind 98. first time i plugged the old drive in comp only recognized the old 10 gig drive. I dont know what to do I am new at computer upgrades and hardware issues.
