I have WD30EZRX-00MMMB0 (originally external); the drive spins, doesnt click, does make a little strange sound RIGHT after the typical getting ready to get recognized sound and then just hangs in BUSY. I got a donor, swapped heads (donor works with failed drives heads 100%), swapped PCB (again donor works 100% with failed drives PCB after ROM swap), heck the donor even has same firmware as the failed drive (swapped failed drives PCB onto the donor no problem).

I know these drives are pretty new; I'm assuming its something to do with the SA. Any suggestions? Thanks!

I think that you open the drive and swapped heads without necessity to do so.

Did you attempt HOT SWAP ? If so were you able to read modules with HOT Swap ? What about reading tracks ?

Also did you attempt this ?

Hi Spildit.
I'm getting the same problem in PC3K.
I can read tracks and modules but i can't get access to data and the drive just hangs in BSY. Do you mind sending me a PM?

Hi.
If the drive is stuck on BSY then it will not read modules and tracks.
If you can read SA and all looks ok but you can't read any data consider the following :

- make sure ROM on pcb is native of the drive as incorrect adaptives will cause problems reading data.

- check re-lo list and s.m.a.r.t. for relocations and apply the slow fix.

- check if you can read any data at all by scanning the drive with universal utility. If no data can be read even scanning on the middle of the drive either translator is damaged or bad heads prevent translator from initializing.

when something like this WD hangs in BSY, isolate heads and wait for Kernel to kick in, then put drive to sleep and block access to SA by regions shift.
repower, upload loader, search modules in SA, use dir in the utility, fix slow response, repower, shift regions back, enjoy.

Hey grig85,

Can you please elaborate on your solution for solving the "BSY" problem.

Thanks,

the procedure if fully described in Marvell_en.pdf manual

Yes.

Thanks guys,

I've applied the slow fix but now the drive is reporting a smaller size in bios, 800GB of a 3TB drive. Has someone else had this issue after applying the slow fix?

Regards,
Profix

Check if HPA is set.
If not maybe mod 02 end up damaged while applying the slow fix...

Hi Spildit,

The box for "Disable Host Protected Area" is unticked. Is this what you mean by Check if HPA is set?

How do I go about testing Module 02 for corruption?

Doing a heads test reveals that heads 2 through 7 have read errors. How reliable is this test?

In a SA structure test, there are a lot of modules that fail a Read. I've attached a result log for this.

The capacity is detected correctly in PC-3000 just not in the bios.

Might be a BIOS limitation for bigger drives that are causing the capacity problem.

Do you have DE ?

I would say that most likely the heads are not working as they should.

I would attempt to clone the drive with DE or do a head map and clone with one head at a time to check at waht speed they are coping and figure out if some head(s) have a problem.

Do you need the data or do you want to re-use the drive ?

Nope, not a bios limitation. The data is the important part. We didn't buy data extractor with our PC-3000. Is there any other cloning software that we can use?

Software - ddrescue ...... But it will not help cloning by heads.

Do you have DDI ? Maybe you should do a quick test with Victoria for windows.

Run Victoria for windows in PIO, do a PCI scan, you will see the PC-3000 card, select the first port, you should see your drive (keep the PC-3000 software open and with power on), check the RHPA and look at the log to see if the drive have HPA. I'ts more easy that way then looking for the option on the universal utility of pc-3000.

If Victoria in PIO mode can see the full capacity of your drive when using the PC-3000 card and only sees 800 GB when the drive is connected to the motherboard port then BIOS/Motherboard are playing with you
