Displays FDRERASE/OPEN log files, which contain details of FDRERASE/OPEN operations against a given disk. A list of available log files is displayed, sorted by device name.

Displays the FDRERASE/OPEN history data, which contains one summary line for every FDRERASE/OPEN operation which has been performed.

Invokes the ERASE function on the checked disk(s). ERASE overwrites each sector on the disk up to 8 times with a data pattern specified by the user. By default, it overwrites 1 time with binary zeros. ERASE is compliant with data erasure requirements that specify that the data be “erased” or “cleared”.

Invokes the SECUREERASE function on the checked disk(s). SECUREERASE overwrites each sector of the disk up to 8 times with a random data pattern involving complements. In other words, the first pattern is random, the second pattern is the complement of the first, the third is random, etc. By default, it does 3 passes. SECUREERASE is compliant with the latest US DoD data erasure requirements and other requirements which specify that the data be “sanitized” or “purged”.

Invokes the VERIFY function on the checked disk(s), used to verify that a disk has been erased. It reads selected sectors from the disk and verifies that they contain a pattern which could have been written by FDRERASE/OPEN.

Invokes a PRINT function on the checked disk(s), which prints selected data in hex.

DELETE TASK deletes requested erase, verify or print functions which have not yet started.
Highlight the line for each task to be deleted, then click the icon.

(Pause) and (Resume) are used to temporarily stop erase, verify or print functions, and restart them.



CANCEL is used to terminate active erase, verify or print functions.


Are used to toggle the FDRERASE/OPEN display between a single panel (as in the example above) and a double panel with the disk subsystems on the left and individual disks on the right.


Invokes the FDRERASE/OPEN options panel.


Allows you to change the FDRERASE/OPEN terminal security password, and the number of minutes of idle time before the keyboard is “locked”.

Invokes FDRERASE/OPEN terminal security and “locks” the keyboard, immediately. The displays are still updated but no functions can be initiated. The current password is required to re-enable new functions. This can be used anytime you expect to be away from the terminal.

The (“power button”) exits from FDRERASE/OPEN, syncs all files on the FDRERASE/OPEN memory stick, and terminates the operating system.
