User interface
Main view:
Pic.1 Main view
Control elements:
Select Drive drop box - contains list of supported storage devices in a system. List
contains models and serial numbers of devices. Icon defines possible device.
S.M.A.R.T. button – generates S.M.A.R.T. attributes report.
Tasks button – shows pop-up menu with tasks
Surface Tests element – opens Test selection windows (see Pic.2)
S.M.A.R.T. element – same as S.M.A.R.T. button click
S.M.A.R.T. Offline Tests – activates submenu with Short, Extended and Conveyance
S.M.A.R.T. tests.
Temperature Monitor element – starts temperature monitoring task
Features element – activates Features submenus.
Identity Info element – generates Identity information report.
Skin selection – opens dialog to select skin
Build Command Line – opens dialog that can build command line for the program

Test selection window:
Pic.2 Test selection window
Control elements:
Start LBA field – determines first logical sector number for testing.
End LBA field – determines last logical sector number for testing.
Block Size field – determines block size for testing (in logical sectors).
Test radio buttons – select type of the test.
Add Test button – adds test into a tests’ queue.
Tests capabilities and limitations:
Can be started 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 restriction on Block Size with 256, 16384 or 65536 sectors because
of Windows limitations.
Verify test may work in improper way on USB/Flash devices.
In Verify mode device reads block of data into internal buffer only and checks for
consistency, there is no data transferring through interface connector. 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. The program
reads block of data into 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 number
of logical sector. The program sends the block of data to drive and drive writes the block
( All data in the block on drive will be overwritten and gone forever! ) 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 testing area. The program measures
operation time.
