Following the release of DiskEng’s free hard disk monitoring software DiskWatch in November, further development work has been ongoing to enhance the application. This Windows software application, designed to monitor the S.M.A.R.T. health status and temperature of each hard disk drive retains all the previous features while now including the ability to do a coarse scan of each disk.
This coarse scan reads sectors at intervals across the hard disk drive, in order to determine quickly if a problem may be developing, which has not yet been detected via the S.M.A.R.T. data. A failed read will terminate the scan immediately, as this indicates serious and possibly terminal problem has been encountered, which should not be ignored. The system should be powered down and the hard disk drive sent to DiskEng data recovery.
The time taken for each read is accurately monitored, which can be used as a guide to determine the health of your hard disk drive. If any single read takes over a second to return, it indicates that although the drive was able to return the requested data, there is a problem, which should also be addressed by sending the hard disk drive to DiskEng data recovery.
If any read requests being monitored during the scan take between half a second and second, it is a fair assumption that the hard disk drive is starting to encounter issues. You may wish to attempt to make a backup of the data held on the drive, as ignoring such issues will probably result in requiring data recovery, sooner rather than later.
