If an error occurs during device I/O then the dialog box appears where you can choose how to handle the error.
The following information is displayed: disk number in the RAID (or #0 for a single disk), sectors where error has occured, attempt number, error number, and error description. After a number of retries (defined by parameters) program waits for a user reaction (unless skipping errors mode in parameters is selected) and the button Retry becomes active.
Abort: Abort current operation.
Button is inactive if the operation is not abortable.
Retry: Retry I/O.
In some cases it is possible to successfully read a sector and continue without data distortion after a number of retries. Button is inactive while I/O is in the progress.
Ignore: Continue operation ignoring the error.
The current operation will be continued but most probably with data distortion. When reading file system structures this may cause missing of some files and directory structure damage.
Ignore all: Continue operation ignoring all analogous errors.
After a number of retries (defined by parameters) program does not wait for user choise but ignore the error and continue the current operation.
Reset: Reopen device after detaching/attaching (Windows NT+ only).
Parameters: Device I/O settings
Confirm, Cancel: Used for %CONFIRM% variable in the Device I/O Handler Script
