If you have a hard drive and Workbench is already installed on it you should be able to save this to a new floppy(s).
If not then you could try using a disk repair utility to extract the files onto a new disk. I've actually found that XCopy can sometimes copy a disk but not the error which is handy.
Failing alll that you can get Workbench disks on Ebay most of the time.
