The disk you have selected for storing the Undo information may not have enough free space to hold all the changes that Disk Doctor will make. It is impossible to determine ahead of time exactly how much disk space will be needed. The disk in drive %c1: only has %d2K free. To be safe, we recommend using a disk with at least %d3K free.
Select CONTINUE to use the disk in drive %c1: anyway.
Select NEW DISK to choose a different drive or diskette.
