Hi Sirs,
this log refers to a WD10JPCX-24UE4T0
Concerning to heads swap compatibility parameters and specifically to microjog analisys, microjog values, taken via Work with ROM>View ROM Information , shows "0" for all heads
Using ACE hexEdit Marvel plugin parser, the output is completely different with values that seems to be randomized and unreal.
Same results are obtained backuping SA from a working drive from the same family: microjog values all set to "0"
How should we approach such a cases? 0 is a real microjog value or ACE tool in FBLIte family is not able to correctly parse 47 module dump to extract microjog?
Besides microjog, using ACE hexEdit Marvel plugin, I see DAC values for each of four heads. No info are provided in the manual and in the blog. What is their function? Are they important compatibility params for head change?
Thank you in advance for your answers
