lost my floppy

hi i have just installed a 2nd hard drive ,i had to
disconect the floppy to access the cables,afterwards the
floppy did't work, i have checked all the conections they
are all secure and the right way round,the device manager
says this is working properly, i boot up normally from
the hard drive, but set it to boot from the floppy in
case i needed to use the 98 start up disc ,now it says on
start up "floppy drives not found. 40". so i have to
press f1 to get going.no problem, but i use the floppys a
lot,i have noticed on removing the floppy drive to check
round it that there is a pin missing 33 not 34 is this ok
or could this be the problem,
any ideas
