Ask Slashdot: Recovering Data From 20-Year-Old Diskettes? 375

First time accepted submitter Zilog writes "The end of the 3.5-inch floppy and the disappearance of associated drives showed to me the need to backup the tens of diskettes that accompanied my youth. Carefully preserved, these diskettes have proved readable for the most part — while some are approaching 20 years old. However, some diskettes have shown surface defects in areas with compressed archives (zip). Any ideas on how to recover (as much as possible) these bad sectors?"

    Write a copy tool that fills in all possible bit combinations for the bad sectors and spits out 100s of zip files instead of just 1. At a max of 1.44MB/zip file, it still shouldn't be much space in modern terms. Then just try to decompress them all and see what the results are.
