It reports each drive's SMART Status and SMART Attribute values, allows you to run diagnostic tests (Quick Test and Extended Test), or erase operating systems and file systems on drives (Write Zeros). If any drive errors are found, WinDlg provides an option to return the drive to a defect-free state through its Extended Test repair option.WinDlg runs on Windows XP and later (including Vista, Win7, Win8 and Win8.1). Supported drive interfaces are: IDE, SATA, USB, Firewire, and SAS.QUICK TEST:The Quick Test can determine (in a short amount of time and with a high level of confidence) whether a drive is defect-free. For maximum confidence, the Extended Test is recommended. The Quick Test option may not be available on earlier IDE drives, SCSI drives, and external drives.The Quick Test checks a drive's SMART Status and performs a SMART Quick Drive Self-Test if the drive supports the SMART feature. If the drive does not support the SMART feature, a partial disk scan is performed instead of a SMART Quick Drive Self-Test. In this case, the scan reads 10% from the drive's OD (Outer Diameter) zone and 10% from the ID (Inner Diameter) zone. I/O operations are confined to the first and last 2 million sectors in the ID and OD to limit the amount of time that this operation requires on large capacity drives.EXTENDED TEST:Typically, the Extended Test runs anywhere from 30 minutes to many hours to test one drive. Larger drives take longer to test; system performance also affects the test time. If a bad sector is detected, this test may stop responding for a few minutes before it continues. By default, the Extended Test is non-destructive.This test is destructive only when you select the repair option after bad sectors are detected.The Extended Test scans the entire disk media from LBA #0 to the maximum LBA. If a bad sector is detected, you are prompted to repair it. If you choose to repair the sector, WinDlg writes zeroes to the bad sector; this causes the drive firmware to relocate the bad sector and return the sector to a defect-free state.WRITE ZEROS:This option can be used to erase operating systems and file systems. QUICK ERASE writes zeroes to the first and last 10% of a drive's sectors or the first and last 1 million sectors (whichever is smaller). FULL ERASE writes zeroes to the entire drive and may take hours to complete (depending on drive capacity and system performance). VIEW TEST RESULT:This function displays recent test results. TO RUN THE PROGRAM: BACK UP DATA:Before you run WinDlg, it is highly recommended that you back up all data for all drives. WinDlg may write to the drive during the Extended Test (refer to the Extended Test for details). As with all utilities that write to a drive, it is recommended that you back up your data before proceeding.TO TEST EACH DRIVE:Double click on one of the physical drives in the list to display the test menu. You can also right-click on a physical drive and select Run Diagnostics to display the test menu. Select a test and click the Start button to start the test. When the test completes, a status is displayed. For the Extended Test, if bad sectors are detected, a repair option allows you to fix any correctable errors. However, when you choose this repair option, data stored in the bad sectors will be lost; thus, this function must be used with extreme caution.WD provides a DOS version of DLGDIAG (called DOSDLG) which can be downloaded from WD's web site and used to repair certain errors that cannot be corrected in the Windows environment.SMART STATUS:Each drive's SMART Status is queried and displayed when you run WinDlg. The SMART Status can be PASS, FAIL, or Not Available. Right-click on a physical drive and select Show SMART Drive Info or double click a physical drive's SMART Status column to view that drive's SMART Attribute values. Some drives (e.g., SAS - Serial Attached SCSI) do not return SMART data, so "Not Available" will be displayed in the SMART Status column (this is expected and is not an error).INSTALLATION:You can run WinDlg directly without installing it. However, you can run WinDlg's Setup program (setup.exe) if you want to create a Programs menu item, a desktop icon, and a Quick Launch icon for WinDlg. Running WinDlg's Setup program requires elevation (i.e., administrative privilege). Starting with Windows Vista, Microsoft changed Windows such that all processes run with the least user privileges possible, so you may need to follow the steps shown below.Here is one way to run WinDlgs Setup program with administrative privilege:-Open Windows Explorer. -Navigate to the directory where WinDlg's Setup program (setup.exe) is located. -Right click setup.exe and select "Run as administrator".-Follow the Setup program prompts.REMOVAL:If you attempt to uninstall WinDlg while WinDlg is running, WinDlg.exe (the WinDlg executable file) will not be deleted from its installation directory. In this case, delete WinDlg.exe from its installation directory before you install a new version of WinDlg.KNOWN LIMITATIONS:On Windows Vista and later releases of Windows (like Win7, Win8 and Win8.1), the Write Zeros test may fail on drives that have partitions. In this case, you will see a WRITE ZEROS error message box with an error message that looks like this: Sector #2048-2304::Write Zeros error! Continue?Run the Write Zeros test again and it should succeed.On Windows Vista and later releases of Windows (like Win7, Win8 and Win8.1), repairing bad sectors may fail on drives that have partitions. In this case, you will see an error message box with an error message that looks like this: Unable to repair bad sectors.This error occurs because Windows Vista (and later releases) prevents software tools from writing data to a drive that has a partition when the write operation is not performed through the file system. This protects the integrity of file system data. You may need to run WinDlg on an earlier version of Windows (like Windows XP) or you may need to run DOS utility DOSDLG (v5.22 or later) to repair bad sectors.ERROR CODES:WinDlg can return the following error codes: 1 = SMART Return Status failure 2 = SMART attribute over threshold 3 = SMART attribute read failure 4 = Open drive failure 5 = Diagnostic Self-Test (DST) not supported 6 = SMART Diagnostic Self-Test (DST) failure 7 = SMART offline command failure 8 = Read sector failure 9 = Write sector failure10 = Set file pointer error11 = Cable test failed12 = Too many bad sectors detected13 = Failed to repair sector14 = Test suspended15 = Read diagnostics sector error16 = Random read error17 = Erase SSD failure18 = Read Verify Sector Ext error19 = SMART Enable operation failure20 = Failed to delete partitions
