HP Designjet z6100- HDD will not wipe

[captainjason10]

Trying to do a secure disk clean on the HDD, tried unsecure, and secure fast and slow, however drive will not wipe. Tried several times, any ideas.

Hello,

you tried:  Disk Wipe DoD 5220.22-M with 5-Pass Mode ?

[captainjason10]

Yes. Only takes 3 or so hours. Service manual claims it to take 40. Process completes, nothing is reformatted, retains current software, loaded paper, and error code 79.04. Have tried 1 pass, 5 pass, and unsecure. Fair to assume that when the drive is reformatted, it should bring you back to some sort of setup screen, i.e language etc. That doesn't happen. Appreciate any help you can provide.

Hi,

thanks for the feedback, if I understood, you would like to perform wipe because you get 79:04?

if yes, when the 79:04 appear? 

did you try ERROM Reset?

[captainjason10]

Yes tried ERROM reset several times. 79.04 appears during paper load.

Hello,

if the FMW is already up to date version: 11.00.02.4

In this case, the HDD replacement is required.

[captainjason10]

Yes it is on the most recent software.  This doesn't explain why the unit will not wipe the HDD. Could it be the main formatter board. The previous HDD I had, I was not able to wipe either

Hi,

Yes according to the troubleshooting and the HDD replacement, you can start with

Cleaning carefully the encoder strip: (Edge 2 Edge)

I have cleaned the encoder strip prior. Could the main formatter board cause the hdd from reformatting?

[Ouccema]

yes please go ahead.
