This article describes how to use TweakTool to read fault location parameter from drive to examine the detailed reason of drive fault.

TweakTool

Tweak tool is a utily to read/write raw parameters from drive by using the USB adapter. TweakTool can be downloaded from this link. The application does not require installing, just extract the ZIP file to local disc.

Acquiring fault location

Preparations

  1. Remove any cable from drive CMD port (the 16 pin flat cable)
  2. Follow instructions from 1-5 in TweakTool screen in order to be able to communicate to drive (see screenshot below). You may need to set Force SPI mode with GDtool if it's not selected.
  3. Close GDtool if it's is running
  4. Launch TweakTool_1.0.exe

Reading the fault location parameter

These numbers are referencing to the image below.

  1. Enter 15440 to parameter number
  2. Click Read parameter
  3. Observe that "Command OK" reads in the status bar. If some error is reported, connection didn't succeed. Ensure that earlier steps are followed.
  4. Fault location value should now display in parameter value

Fault location expanations

Fault location changes only during fault and does not stay in memory after power-off. Read fault location after fault has occurred before shutting down drive.
