A Kryoflux or SuperCard Pro can sometimes do even better at recovering damaged disks. A while back I recovered a disk that had a pile of sectors as bad, but only a few bits in each sector were wrong. Luckily the CRC data was all intact, so with a bit of MFM text file editing, pattern matching, and guess work I was able to fix it 100%.
Windows 95 OSR 2.5 was just 2.1 with IE 4 and a different USB update installer.
Which raises the question, was IE 4 ever released on floppy disk? And would a floppy set be more or less potent than the CD when performing satanic rituals?
