HM500JI stay busy after Hot swapping : No overlay code

[hddr49]

Hi there,

I have one HM500JI with no terminal output at all.

Let's go for hot swapping...

like another user,
1. Power on donor. Run the utility. Wait until initialization will complete,then put drive to sleep mode. - OK
2. Unscrew the PCB from donor and install it on patient drive.Screw the screws back. And perform recalibration. - OK
3. Wait until the drive will enter ready state, then read the modules from the drive except some "big capacity" log modules. -OK (I read all modules and save)
4. Power off donor PCB and swap it on donor HDA. - OK
5. Write all necessary modules(All of them - family is not in the list) from patient to donor drive .Then switch drive's Power off/on. - stop..

When switch drive's Power off/on then doner HDD is not ready.

It stay busy, and I have terminal output :

Code: Select all

I try to check the modules integrity, but there are 148 of them...

can you help me ?

thanks

Hi,

Did you rewrite 73 Overlay?

[AJ2008]

And did you write to all available SA copies?

thanks for your interest of this case, but case is closed.

I swap with exact donnor (no hot swap, cold swap), and recover all data

thanks again
(other case on WD6400BEVT is harder - make me crazy)

Overlays from donor must write correctly, then donor ROM gives access.

Great that you got data recovered
