DLGDIAG 5.04f Version Problem with WD20EARS

The program source is the .ISO downloaded from WD.

The error message is:

“Western Digital drives were found.  However, none of them are supported in this version of the program.”


Gigabyte G31M-ES2L in various SATA modes.


WD20EARS, jumper installed for XP. SATA-0


Samsung DVD/RW as SATA-1

The DOS version of DLG hasn’t been updated in a long time, so newer drives are not supported.  The Windows version of Diagnostics should work fine, if you can use it.  What are you trying to do?
