We recently discovered and corrected an error affecting the above series. In some floppy drives a disk error was generated when a 720 KB diskette was inserted in a 1.44 MB drive. The BIOS erroneously detected a 720 KB diskette as a 1.44 MB diskette. This problem occurs only in certain 1.44 MB drives; 1.2 MB drives are not affected.
The problem has been solved by modifying the media detection routine in the BIOS. The following ECNs have been issued in the form of a BIOS release to correct the problem: Series 29, ECN29.003; Series 39, ECN39.005, and Series 43, ECN43.002.
