How to Test your hard drive ?

Test your hard drive.

HDDScan is a freeware software for hard drive diagnostics (RAID arrays servers, Flash USB and SSD drives are also supported). The program can test storage device for errors (Bad-blocks and bad sectors), show S.M.A.R.T. attributes and change some HDD parameters such as AAM, APM, etc.

Hard Drive Failure?

If your device is making any abnormal noises stop immediately, do not try to turn on the device and contact a professional data recovery company.

DigiLab Data Recovery Services is recommended and approved by the developers of the HDDScan utility.

HDDScan can be useful for performing the regular "health test" for your drive and predicting its degradation, so you will be able to prevent data loss and backup your files before you would have to contact the data recovery service.
Additionally, software can be used as the hard disk temperature monitor and reading/writing benchmark – performance graph is displayed for every test.

    When you click on TOOLS button, the pop-up menu would offer you to choose one of the following options.

    • DRIVE ID – generates Identity information report.
    • FEATURES – opens ATA or SCSI features control
    • S.M.A.R.T. TEST – activates a dialog with Short, Extended and Conveyance S.M.A.R.T. tests.
    • TEMP MON – starts temperature monitoring task.
    • COMMAND – opens a dialog that can build command line for the program.

    Control elements:

    • FIRST SECTOR – determines first Logical Block Address (LBA) for testing.
    • SIZE – a number of LBAs for this test.
    • BLOCK SIZE – indicates Block Size for testing (in LBA sectors).
    • Previous button – returns the program on the Main screen.
    • Next button – adds the test into a tasks' queue.

    Tests capabilities and limitations:

    • Only one test at a time. Author wasn't able to get stable test results with two or more simultaneous tests.
    • Verify test may have restrictions on Block Size with 256, 16384 or 65536 sectors because of Windows limitations.
    • Verify test may work in unreliable way on USB/Flash devices.
    • In Verify mode device reads block of data into drive's internal buffer only and checks for consistency, there is no data transfer through an interface connector/cable. The program measures operation time for each block. The program tests blocks one by one from minimum to maximum.
    • In Read mode device reads block of data and transfers it thorough interface to the host controller. The program reads block of data into a temporary buffer and measures time of operation for each block. The program tests blocks one by one from minimum to maximum.
    • In Erase mode the program prepares block of data field with special pattern and an LBA number. The program sends the block of data to the drive and the drive writes the block (All previous data in the block on the drive will be overwritten with the pattern and cannot be recovered after that!) The program measures operation time for each block. The program tests blocks one by one from minimum to maximum.
    • Butterfly Read mode is similar to Read mode difference only in blocks' order. Blocks are tested by pairs. The first block in the first pair will be Block 0, the second block in the first pair will be Block N (where N is number of last block for testing). Next pair will be Block 1 and Block N-1. Test ends in the middle of the testing area. The program measures operation time.

    Tasks Manager window

    This window shows a tasks queue. All surface tests, S.M.A.R.T. tests and Temperature Monitor tasks will be displayed in the Tasks Manager Window.

    Double clicking on a task line will open task information window (alternatively you can select Show Details option from the menu of the Tasks Manager).

    Test information window

    This window contains information about selected test. Test could be paused or stopped and report with results can be generated.

    Graph Tab:
    Displays testing speed for each block. Information is represented as a graph.

    This window contains information about selected test. Test could be paused or stopped and report with results can be generated.

    Map Tab:
    Displays response time for each block. Information is represented as a map.

    You can select "Block Processing Time" in milliseconds. Every tested block that would have taken operation time longer than the "Block Processing Time" would be logged in the Report tab.

    Identity information

    Report contains information about physical and logical parameters of HDD. Report can be saved to an MHT file.

  • Image
    S.M.A.R.T. report

    Report contains information about drive's performance and "health" described in attributes. Green icon means - attribute values are normal. Yellow icon marks important attributes which may indicate HDD's malfunction. Red icon indicates abnormal attribute values.

    Report can be saved to an MHT file.

  • Image
    Temperature monitor

    Monitor allows evaluating HDD's temperature. Temperature is indicated on the Task bar and in an information window.

  • Image
    Temperature monitor for ATA/SATA HDD

    For ATA/SATA/USB/FireWire drives the information widow displays two values. The second value is shown on the Task bar and represents temperature from HDA Temperature attribute.

    The first value indicates temperature from Airflow Temperature attribute.

    If the second value is not supported be the drive then the fist value will be shown on the Task bar.

  • Image
    Temperature monitor for SCSI HDD

    For SCSI drives the information window shows two values. The second value is shown on the Task bar and represents current temperature.

    The first value indicates maximum allowed temperature for HDD.

  • Image
    S.M.A.R.T. tests

    The program can run three types of tests:

    • Short test - lasts about 1-2 minutes. The test inspects drive's main electronics, scans small part of drive's surface and checks sectors from the Pending-list (such sectors may have read errors). This test recommended for a quick drive testing.
    • Extended test - could take 0.5-60 hours, depending of the size of the drive. The test inspects drive's main electronics and scans the whole drive's surface.
    • Conveyance test - usually lasts several minutes. The test inspects drive's main electronics and logs that may have records which could indicate incorrect transportation or storing.

    The SMART Test can be selected from the SMART tests dialog that can be called by pressing SMART TESTS button

    S.M.A.R.T. tests

    After selecting, the test will be added to the Tasks queue.

    SMART Tests details window can show progress and completion status.

    Features

    The program might be able change some parameters for ATA/SATA/USB/FireWire HDD:

    • AAM - this function changes drive's acoustic. If this function enabled drive's noise may be decreased by smoothing HSA's seek operations. HDD could lose some performance.
    • APM - this function allows power savings by temporary decreasing spindle's rotation speed (including complete stop) when drive is in idle.
    • PM - this function allows setting spin-down timer. If drive is in idle spindle would be stopped after the time set in the timer. If any program requests HDD access the internal timer will be reset and spindle will continue to spin.
    • The program can also start or stop spindle immediately. If any program requests HDD access drive's spindle will spin up.

    Features

    For SCSI/SAS/FC drives the program can show defect-lists and start or stop the spindle.

    Command Line Dialog

    HDDScan can build a command line and save it to .cmd or .bat file. When you run such file the program starts in background mode, changes selected parameters and closes automatically.
