uBeeDisk is a tool that copies disks and images from one to another. It was developed to archive Microbee disk images from floppy disks and to write them back to floppy, but other disk formats can be added. It is intended mainly for users of computer emulators. As the program makes use of the 'LibDsk' library there are many options for image types. The program provides some data recovery methods along with 'info' files for each disk image file created. An 'info' file contains information about the disk image, a status map of all sectors read from the disk, and an MD5 stamp of the associated disk image.
