The script can be used for I/O error logging and for extended processing of errors (include external program calls). The feature is available in the Professional Edition only.
Script can be loaded or modified via Device I/O Parameters (button Script).
The file ondevhsc.txt contains a brief description of available commands and some script examples.
Possible script lines are of the form:
IF CONDITION COMMAND
or
COMMAND
or
:LABEL
where CONDITION is an inequality or equality
(!=, >, <, >=, <=, =) of two quantities,
and quantity is either an integer constant (0, 1, ...)
or a variable (the list is below)
or a simple mathematical expression (operators +, -, *, %, /,
without parentheses, ignoring the mathematical order of operators),
e.g. %ERROR%=0
Comments are preceded by two minuses (--)
| %CONFIRM% | =1 if Confirm pressed, =0 if Cancel pressed (confirmation dialog box appears) |
|---|---|
| %DISKNUM% | disk number in RAID array |
| %TRYNUM% | i/o retry number |
| %LBA% | first i/o sector number |
| %SECNUM% | number of i/o sectors |
| %ERROR% | i/o error |
| %ERROREX% | additional error code for IO SCSI, IO ATA access modes |
| %ATASTATUS% | ATA Status Register value (defined if BSY bit is cleared, DOS ATA only) |
| %ATAERROR% | ATA Error Register (defined if ERR bit of %ATASTATUS% is set) |
| %LINE% | current line number in script |
| %SERVICE% | i/o service: 0-ATA 1-ATAPI 3-BIOSINT13OLD 4-BIOSINT13 5-DOSINT25 6-DOSINT73 7-DOSASPI 8-DOSMSCDEX 9-DOSFILE 11-WINFILE 12-WINSCSI 13-WIN9XINT13 14-WINATA 20-LINUXFILE 21-LINUXSCSI |
| %LASTRES% | result of the previous command |
| %LASTERR% | error of the previous command |
| SHOWDLG - force device i/o dialog box popping up |
| WAIT - wait for user choice |
| DELAY N - delay for N msec |
| EXECCMD CMDLINE - execute external command CMDLINE using Command interpreter (equals "cmd CMDLINE" in Windows) |
| EXECCMDQ CMDLINE - execute without creating new console window (quiet) |
| EXEC "FILENAME" CMDLINE - call external programm FILENAME with parameter CMDLINE |
| EXECQ "FILENAME" CMDLINE - call without creating new console window (quiet) |
| MSDOS - call Command processor (OS Windows and DOS) |
| GOTO LABELNAME - jump to label LABELNAME in script (to the string :LABELNAME) |
| RETURN - break script execution, handle error according to device I/O params |
| RETRETRY - break script as Retry button pressed |
| RETIGNORE - break script as Ignore button pressed |
| RETABORT - break script as Abort button pressed |
| ADDLOG "FILENAME" LOGLINE - write LOGLINE to file FILENAME (string LOGLINE may contain variables) |
| CANCELIO - Call CancelIO (WinNT+ only) (available if a device is opened with overlapped option) |
| OVLRESLT N - Check Overlapped result (N=1: wait; N=0: not wait) (WinNT+ only) (must be used if a device is opened with overlapped option) |
| RESETHANDLE - Reopen disk handle |
| RESETDEVLIST - Update the list of devices, reopen disk handle |
| ATARESET - ATA Soft Reset (DOS ATA only) |
| ATARESETDET - ATA Soft Reset followed by ATA Identify (DOS ATA only) |
To format output integer a variable name can be followed by a format specifier after a colon, e.g.
%LBA:8x% -- width: 8, hexadecimal
IF %ERROR%=0 RETURN -- return if no error on last i/o
IF %ERROR%=128 GOTO LABEL1
IF %ERROR%=5 GOTO LABEL1
RETURN
:LABEL1
IF %CONFIRM%=0 RETRETRY
-- retry if Cancel button is pressed
-- continue script execution if Confirm is pressed
EXECCMD /K ECHO error %ERROR% at LBA: %LBA% (%SECNUM%) try: %TRYNUM%. Type EXIT to return.
IF %TRYNUM%<2 RETRETRY
DELAY 500
ADDLOG "C:\ERRORS.LOG" error %ERROR:x% at LBA: %LBA:10% (%SECNUM%) try: %TRYNUM%
RETIGNORE
