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.

DOWNLOAD - Version 4.1

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.

 * TOOLS button – shows pop-up menu to select available drive's controls and
   features.
 * More button – shows drop-down menu with program controls.

When you click on TEST button, the pop-up menu offers you one of the tests. If
you select any test – the Test selection dialog will be opened.

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.

TEST SELECTION DIALOG

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.

TEST SELECTION DIALOG

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.

TEST INFORMATION WINDOW

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.

TEST INFORMATION WINDOW

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

Report Tab:
Contains information about selected test and each tested block on a drive which
responding time was longer than the "Block Processing Time".

IDENTITY INFORMATION

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

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.

TEMPERATURE MONITOR

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

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.

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.

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.
