Work with diskette data recovery

It allows you to read data from a diskette that contains cyclic redundancy check (CRC) errors. CRC errors occur when the system finds data on a diskette that is not readable during a read operation. Normally, when the system finds a CRC error, you cannot read the diskette past the point of the failing sector. By using this option, you can read diskettes that contain sectors with CRC errors.

The iSeries® system can use diskettes for saving and restoring system objects. One or more objects can be stored on a diskette. Whenever the system finds a diskette that contains a bad sector during a read operation, the operation ends. A bad diskette sector, which causes a CRC error, can result from failure in the diskette or from wrong handling. The Work with diskette data recovery option allows you to read data from a diskette, correct any failing sectors present on the diskette, then write the new data to a new diskette.

Options

• Alter diskette data

  This option allows you to change the data in any sector on a diskette. For more information, see Alter diskette data.

• Read data from diskette

  This option reads the contents of a diskette while ignoring diskette sectors with read data CRC errors. For more information, see Read data from diskette.

• Write data to diskette

  This option writes the volume table of contents (VTOC) and data sectors to a new diskette. For more information, see Write data to diskette.

• Display diskette data

  This option allows you to display the data in any sector on a diskette. For more information, see Display diskette data.

• Print reports
  This option allows you to print the following reports from the diskette:

  • Volume label
  • Data set label
  • Load or dump object descriptor
  • Failing sector
  • Sector range

  For more information, see Print reports.
