[comp.sys.ibm.pc] Help w/ BACKUP: Unrecoverable file sharing error

keith@curry.uchicago.edu (Keith Waclena) (10/16/89)

A friend of mine has a DOS 3.1 problem.  She was backing up her hard
disk using the DOS backup program with /m and /a to add modified files
to the end of the previous backup, when backup aborted with the
message:

    Unrecoverable file sharing error

The PC in question isn't networked and doesn't run share.exe (perhaps
it was once run by accident; several users use the PC, but most of
them use a menu; share.exe isn't in autoexec.bat).

The DOS manual has the following useful info for this error:

    MESSAGE:	Unrecoverable file sharing error
    CAUSE:	BACKUP, RESTORE
    ACTION:	None

Note that this is repeatable and she's unable to do a backup, although
the disk seems to be okay otherwise.

So, can anyone tell me: 1. The actual reason for this message, 2. What
exactly share.exe is doing (does it modify files or directory entries
on the disk somehow?  She still can't run backup after rebooting), and
3. How to fix this problem?

Thanks in advance!
