Best Software For Checking Bad Sectors Disk
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.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. Control elements:. Select Drive drop box - contains a list of supported storage devices in a system. The list contains models and serial numbers of the devices.
Icon defines possible storage type. S.M.A.R.T. Button – generates S.M.A.R.T. Attributes report.
TESTS button – shows pop-up menu to select read and write tests. 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.Test selection pop-up.
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 windowThis 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.Graph Tab.
TestsThe 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 buttonSMART Tests Dialog. FeaturesThe 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.
