FDISK Problem–Bad Track Error in MS-DOS 3.20 and 3.21 PSS ID Number: Q25639 Article last modified on 07-14-1993 PSS database name: O_MSDOS

3.20 3.21


The information in this article applies to:
- Microsoft MS-DOS operating system versions 3.20 and 3.21


MS-DOS Version 3.20 FDISK does not check to determine if the first several cylinders of a DOS partition are good. This problem subsequently causes FORMAT to fail with an obscure error message. IBM PC-DOS Version 3.20 FDISK works properly.

Microsoft has confirmed this to be a problem in MS-DOS versions 3.20 and 3.21. This problem was corrected in MS-DOS version 3.30.
