This drive is being very strange.

Only have Atola at my use right now so cannot check it's behavior on another device:

Drive comes in, is clicking. Click, recal attempt (the kind of rpm slowdown/speedup), repeats 3 times and spins down, then tries again a few times.

ID as HAWK, serial # XYZ etc etc.

When is see this i usually don't call it heads first, because in my experience it is often not.


First thing I do is put the PCB on a known good drive (very close in match) to see if it has the same symptoms.

It does, so first I try to transfer ROM to new PCB and see what happens.

Same results.

Now I am on to firmware.

Hot-swap grants me access to firmware map. Perform a backup and see that several of the Device config modules, as well as some other less critical modules.

Replace the unreadable modules; the only one that is not replaced is 1 Selfscan log. This is now the only module that is not readable.


Here is where it gets strange to me:

The new PCB with original ROM still clicks

The PCB from the drive I used for Hotswap does not click, but reports HAWK, etc. It DOES grant me access to SA though.


I am confused to say the least.

The only thing I can think is either there is some corruption to SA that I cannot see (maybe module is readable, but there is trash, etc)

or

Bad Head/s is causing the drive to behave oddly.


After the write of the new modules I can read them back, and verify that they where written correctly...so the write element of the head is not corrupting the data on the write attempt.


I'll report back when i figure something out.

try smart hot swap and build head map

it's easy to do. and this drive have 6 head. head map 0~5. i have same model in stock. please let me know if need any help.

I am sure it is easy to do when you have PC3K, but I currently do not have access to one, so I cannot rebuild headmap at this time.
