do you have access to another computer,the easiest way would be to put that drfive into another pc,then burn the data to a cd,,,as its that old,,you may get the whole hard drive on a DVD or 2...
alternativly,get another hard drive then copy the data to it via dos using a win98 boot floppy from,,,,http://www.bootdisk.com/
then use the copy command to copy it to the other hard drive....
the 1st suggestion is thre easiest.....or you search for a bootable version on 98pe cd,,this allows you top boot into 98 without installing it (runs from the cd)then you can copy you files to floppies etc.
