Well, it depends on the value of the data whether to worry or not. If it
really is important data and the disk already shows some harddisk errors
(one possible reason for the failure to boot), then it might be really
dangerous to strain the fragile device with time consuming windows
defrag instead on focussing on getting the data off the dying disk.
