Purpose

Syntax  

 

Syntax Element

Description

/P

Positions to the specified disk segment, but does not display it.

/S

Shows a short formatted display of the disk segment.

/M

Shows a medium-length formatted display of the disk segment.

/L

Shows a long formatted display of the disk segment.

/H

Shows a hexadecimal display of the disk segment.

/V

Verifies the disk segment and displays any errors encountered.

/C

For compressed data blocks, displays the uncompressed DB header information, including extended header information pertaining to data compression.

If the scoped DB is not compressed, the output is similar to the display when the /S option is used.

/Z

For compressed data blocks, displays:

  • the uncompressed DB header information, including extended header information pertaining to data compression.
  • a hex format display of the compressed data stored in the DB. If the /Z option is not used, the hex display shows the uncompressed data.
  • If the scoped DB is not compressed, the output is similar to the output when the /x option is used.

    cylid

    The 64-bit identifier of a cylinder, entered as a 16‑character hexadecimal number.

    sectornum

    The sector number.

    sectorcount

    The number of sectors to display, starting from sectornum. If sectorcount is omitted, DUMPDISK will display one sector.

    =

    Filer will use the most recently saved values for cylid, sectornum, or sectorcount.

    This option cannot be used unless input values have already been defined for cylid, sectornum, or sectorcount. For more information, see “Stored Input Values” on page 82.

    Usage Notes  

    If the type is invalid, the segment is displayed in the hexadecimal format. This command differs from the BLK command because data is always dumped from disk.
