RECOVER Should Not Be Used If CHKDSK Reports Bad Sectors PSS ID Number: Q64841 Article last modified on 07-15-1993 PSS database name: O_MSDOS

3.20 3.21 3.30 3.30a 4.00 4.01

MS-DOS

Summary:

The “Microsoft MS-DOS User’s Reference” RECOVER entry for versions 3.20, 3.3 and 4.x (see More Information, below) incorrectly states the following:

If the CHKDSK command shows that a sector on your disk is bad, you can use the RECOVER command to recover each file on disk or just the file containing the bad sector.

This is incorrect. Bad sectors reported by CHKDSK were marked as “bad” when your disk was first formatted; therefore, MS-DOS did not write any data to them to recover. These bad sectors pose no danger and RECOVER cannot help.

More Information:

The error in the RECOVER entry occurs in Chapter 3 of the User’s Reference on the following pages, depending on which version of MS-DOS and the MS-DOS user’s reference you have:


 * “Microsoft MS-DOS User’s Reference” version 3.2, Page 77
 * “Microsoft MS-DOS User’s Reference” version 3.3, Page 103
 * “Microsoft MS-DOS User’s Reference” version 4.01, Page 113

This error does not occur in later versions of the “Microsoft MS-DOS User’s Reference.”
