Syntax:
RECOVER [d:][path]filename
RECOVER d:
Purpose: Resolves sector problems on a file or a disk.
(Beginning with
DOS Version 6, this program is no longer available; in DOS Version 6 and
later,
use the ScanDisk utility.)
Discussion
If a disk develops problems, you can use this command to attempt to fix
sector
problems. You can recover either the file containing that sector (but
without
the bad sector) or the entire disk (if there were sector problems in the
disk
directory area).
Examples
To recover the file NEWFILES.TXT, enter
recover newfiles.txt
The program will read the file, sector by sector, skipping the bad
sectors.
When a bad sector is found, the sector is marked and DOS will no longer
allocate
your data to that sector.
To recover the disk in drive A, enter
recover a:
Each recovered file will be listed in the directory in the form
FILEnnnn.REC,
where nnnn is a sequential number starting with 0001.
If there is not enough room in the root directory, a message will be
printed and
the program will store information about the extra files in the file
allocation
table. You can run RECOVER later to regain these files (after you have
removed
files to make more room in the root directory).
For more information about this command, refer to the downloadable book DOS the Easy Way.
