![]() For more information, please check:Įach tests have different configuration options: The test is best to be used to repair drives with weak sector(s) without the need of complete backup (and use of the Reinitialize disk surface test) and works on both system and secondary drives too. File(s) on the affected repaired sectors are listed when the test completed. The test is safe for stored data and the damaged file(s) will be readable, however file fragment(s) on damaged sectors may be corrupted. Disk Repair (Pro version only) - Reads the disk surface to verify if all sectors are readable and forces the disk drive to repair any problematic (pending, weak) sectors: restore the status to good or reallocate (replace from spare area) if required to prevent further use of the original sector. (Navso P-5239-26 standard data destruction). It can be effectively used to permanently destruct stored information The simple version of this test is usually (incorrectly) called as low level formatīy other tools. Forces the analysis of any weak sectors and verifies any hidden problems andįixes them by reallocation of bad sectors (this is drive regeneration).Īs after the test the spare area will be used instead of any problematic sectors.Īnd time-consuming test, especially if the level (the number of overwrite cycles) is set Restore the sectors to default (empty) status and reads back sector contents, to verify if they areĪccessible and consistent. Reinitialize disk surface (Pro version only) - Overwrites the disk surface with special initialization pattern to ![]() To backup important data before this test. Memory/power supply/cable problems and other factors.Īrea of the storage device, without the need of complete erase but it is still recommended The operation is usually safe for the stored information butĭata loss may occur if the system is not stable and/or upon power failure, overclocking, The error correction (drive regeneration). By the extensive test,Īn additional write cycle is used before writing back the contents to improve the efficiency of The contents and finally reads the information and compare with original contents. Read + WRITE + read test (refresh data area) (Pro version only) - Reads stored data from each blocks, writes back Verifies any hidden problems and fixes them by reallocation of bad sectors (this is driveĮnables better use of the disk as after the test the spare area will be used Forces the analysis of any weak sectors and Sector contents, to verify if they are accessible and consistent. ![]() WRITE + read test (Pro version only) - Overwrites the disk surface with configurable pattern and then reads back It is also possible to specify FILE=existing file name, then the contents of the file will be used as overwrite pattern. In this option, it is possible to enter hex sequence, for example 0x99 0x88 0x77 to write such bytes. ![]() For example entering ABC in the byte/byte sequence field will cause that all sectors will contain ABC string Also it is possible to specify any byte/byte sequence as overwrite Useful in later data recovery) or even random data. Writes zeroes (00 bytes) but it is possible to specify that all sectors should contain the sector numbers (may be Note: on the Configuration page, it is possible to configure the pattern to be written by Forces the analysis ofĪny weak sectors and verifies any hidden problems and fixes them by reallocation of bad sectors (this isĮnables better use of the disk as after the test the spare area will be used instead WRITE test - Overwrites the disk surface with configurable pattern. Test is safe, it does not affect stored data.ĭisk problems may remain hidden and revealed disk issues READ Test - Reads the disk surface to verify if all sectors are accessible and readable. The amount of disks to be tested is not limited (just the overall system performance/resources may limit them). It is possible to use the "Multiple disk drives" button to select more disks to be tested at the same time using the same test method, options and settings. Strongly recommended to read these information carefully before starting the test. The test are displayed upon selection, and the software displays how the test affects stored data. Methods are safe for the stored data but others are destructive: the stored information are permanently erasedįirst it is required to select the hard disk and the test type to be started. By using this test, the surface of the hard disk can be examined with different methods.
