Improvements and new features:

• added new disk testing method: Disk menu -> Surface test -> Repair disk drive
  designed to repair weak/pending sectors: forces the hard disk to stabilize problems and force reallocation of bad sectors
  (if required). Can be used on even system drive with running operating system (registered Pro version only)
• added manual repair of any disk sector in Disk Contents Inspector:
  use Disk menu -> Surface test -> View (or start any surface test) and click on the disk surface map to view the raw contents of any sector. Go to the appropriate sector and if it is unreadable/reports error, the Repair button attempts to repair that (Pro version only)
• added option to provide disk status information via WMI
  (Configuration -> Advanced options -> Provide status information by WMI)
  (disk information, status, health, temperature, text description, power on hours, bad sector count, weak sector count, comm.issue count, spin retry count, trim status, and complete S.M.A.R.T.) (registered Pro version only)
• added option to test multiple hard disks by Disk menu -> Short self test / Extended self test (registered Pro version only)
• added option to test multiple hard disks by Disk menu -> Surface test functions, by same test methods/options (registered Pro version only)
• added support of high-DPI displays, including but not limited to 4K displays with high DPI scaling
• added option to use TLS / STARTTLS in e-mail configuration regardless of port (previously used automatically only when port 587 specified)
• added option to specify maximum try count in Disk menu -> Surface test functions before starting the test (Configuration tab)
• added "lifetime writes" to TXT / HTML / XML reports
• added option to perform write testing with any byte, byte/character sequence
  Disk menu -> Surface test -> Write test -> Configuration page -> Write pattern
  Specify 0xAA 0xBB etc. to specify hexadecimal sequence
• added option to automatically save all results of disk tests:
  Configuration -> Advanced options -> Automatically save disk test results to folder
  saves images/graphs, log, results, block performance details after Disk menu -> Surface test functions
  saves image after Disk menu -> Random seek test function
  saves text report and brief log after Disk menu -> Short self test / Extended self test functions
• automatic save of complete report upon disk status change/degradation (registered Pro version only)
• added option: Configuration -> Advanced options -> Automatic detection based on disk utilization
  automatically prevent detection if the disk utilization shows that the hard disk is inactive (sleeping), there is no data transfer, no read/write commands (based on the Disk Performance page)
• added option to log alerts to Windows event log: Configuration -> Message settings -> Add to Windows event log (registered version only)
• added option to Configuration -> Message settings to execute external command (or BAT file) when alert triggered (registered Pro version only). The following environment variables set to be accessible from the started external command (or BAT file):
  HDS_TimeStamp : date and time of the actual alert in fixed format yyyymmdd hhmmss
  HDS_TimeStampClean : date and time of the alert in user-friendly format (current Windows regional setting)
  HDS_Host : current host (computer) name
  HDS_Alert : the alert (eg. Overheat)
  HDS_Disk : affected disk(s)
  HDS_Threshold : threshold configured (contain Celsius/Fahrenheit or % symbols)
  HDS_ThresholdValue : threshold configured (only the number)
  HDS_Health : generic health information of all drives
  HDS_Partition : generic partition information of all drives
  HDS_LowestDiskHealth: the lowest health % value of all drives

Improved hardware support:

• added support for InnoDisk industrial (micro) SD memory cards: detection of complete status, health, lifetime writes and additional statistics of (micro) SD memory card.
• added support for Delkin industrial (micro) SD memory cards: detection of complete status, health, lifetime writes and additional statistics of (micro) SD memory card.
• added support for MagicRAM industrial (micro) SD memory cards: detection of complete status, health, lifetime writes and additional statistics.
• added support for industrial (micro) SD memory cards and USB devices based on Hyperstone controllers: detection of complete status, health, lifetime writes and additional statistics.
  
  To enable status detection of industrial micro SD card detection, please select the card reader device from the list of drives and click on the Control device-specific detection label on the right, below the text description area. A new window appears, where it is possible to enable the detection. You may click on the Auto Detect button to verify if the device is responding to the detection. If yes, then the device type will be automatically selected.
  Note: in the unregistered version, the above procedure need to be done every time the software started.
