I had a WD400BB-75JHC0 come in clicking. Checked everything out on the PCB and determined the head had failed. I didn't have an exact match drive, but I did have an 80GB drive that was suitable (WD800BB-00JHA0). 5th and 6th letters for both drives were YT on the DCM. The 80gb drive simply had an extra head that would be rendered inactive by the system area.

The head swap went fine. After aligning the head, the drive calibrates, and comes ready without any problem at all. However, when I go into check the modules the G-List (mod 34) and the Translator (mod 32) are both unreadable on copy 0 and copy 1. Everything else reads just fine. I ran a head test to just to make sure everything was cool with that, and it passed as well. Any ideas on what can be done to clear up the issues with the G-List and Translator in order to gain access to the data?

I think SMART mod's (21,22) are unreadable too, ?

No. They are fine. Self Scan E1-E5 and E9 modules are yellow however.

Check u PM

Nevermind, I got it working now. Just needed to use a little common sense.
