Seagate 5400.6 not detected

[StockEdde]

Hi,

I have a Seagate Momentus 5400.6 ST9320325AS that suddenly disappeared and freezes the machine (it was connected to a Xbox 360 (SATA)). It is not detected in BIOS on pc.

There is nothing of value on the disk and I am a novice on this. However I don't like leaving things unsolved (and I managed to unbrick a 7200.11 earlier on), so I'm giving this a shot.

Here is what shows up in PuTTy when connected serially:

LED:000000CD FAddr:0024F657
Rst 0x08M
RW cmd 0002 req = 3D 49 00 00 08 00 00 00 00 00 00 00 49 1D 05 00 48 21 05 00 49 1D 05 00
opts = 00001121

RW Err = C3160080

RW cmd 0002 req = 3D 49 00 00 01 00 00 00 00 00 00 00 49 1D 05 00 48 21 05 00 49 1D 05 00
opts = 00001121

RW Err = 43110081

RW cmd 0002 req = 29 6A 02 00 08 00 00 00 00 00 00 00 49 1D 05 00 48 21 05 00 49 1D 05 00
opts = 00001121

Etc.

(Not possible to write commands)

And here is what I get when I isolate pcb and is able to communicate (U and Z commands seemed simple and harmless enough, thats why I tried them):

ASCII Diag mode

F3 T>/2

F3 2>Z

Spin Down Complete
Elapsed Time 0.131 msecs
F3 2>U

DiagError 00006008
Spin Error
Elapsed Time 12.227 secs
R/W Status 2 R/W Error 84150180
F3 2>

The disk spins up nicely and there are no squeks or clicks. The connector between pcb and the rest are cleaned.

How do I proceed? Is it software error and potentially fixable or is it truely a brick?

Thank you

It is most likely a logical error.

you need to reattach pcb before spinning it up.

continue only if you can afford loosing data. If not, contact Bosse:
