gives an option for the operating system or the system administrator to identify soon-to-fail drives so they can be replaced before any data loss occurs. Since drives usually don’t fail abruptly, S.M.A.R.T. would allow anticipating predictable failures such as those caused by mechanical wearing or degradation of the disk surface, as well as unpredictable failures caused by an unexpected defect. and can also perform on-demand tests on the drive. will monitor several disk parameters during normal drive operations, like the number of reading errors, the drive startup times or even the environmental condition. –for Self-Monitoring, Analysis, and Reporting Technology- is a technology embedded in storage devices like hard disk drives or SSDs and whose goal is to monitor their health status. The program measures operation time.S.M.A.R.T. Test ends in the middle of the testing area. 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).

Butterfly Read mode is similar to Read mode difference only in blocks' order.

The program tests blocks one by one from minimum to maximum. 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.

In Erase mode the program prepares block of data field with special pattern and an LBA number.

The program reads block of data into a temporary buffer and measures time of operation for each block.

In Read mode device reads block of data and transfers it thorough interface to the host controller.

The program measures operation time for each block.

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.

Verify test may work in unreliable way on USB/Flash devices.

Verify test may have restrictions on Block Size with 256, 16384 or 65536 sectors because of Windows limitations.

Author wasn't able to get stable test results with two or more simultaneous tests.

The program should not be run from a read-only device/media.

Reading in linear mode – same as verification but also transfers data to the host.

Verification in linear mode – fastest way to determine if your drive needs data rescue, has recoverable errors or in its perfect shape.
