I have an old TP disk-enclosure from a 170MB 2.5" hard disk, and would like to replace the disk inside with a 1.3GB 2.5" disk. If someone has hooked up a 1.3GB to a 755CX, or knows what IBM is selling inside the enclosure (if they are selling 1.3GB disks), please let me/us know. Regards, /ivo welch
