Two possible threads here, but related, first off:

BARRACUDA XT / ST4000DX000 / Z1Z02W9Q / 1CL160-570 / CC43 / 13105 / TK

PCB: 100706008 REV A

Symptoms of patient HDD: Disk does not spin up. HDD reports as BSY but quickly alternates between BSY and DRD/DSC whilst giving the following continuous output in terminal:

Boot 0x80M
LED:000ð
Boot 0x80M
LED:000ð
Boot 0x80M
LED:000ð

etc...

When patient PCB is removed from patient HDA and powered on the terminal output is the same. The contacts on the PCB have been cleaned.

When using a non matching PCB from a ST3000VX000 (100664987 REV A) the patient HDA spins up. Obviously there are tracking noises as an incorrect PCB and ROM are being used. However, the HDD sounds reasonable.

I currently do not have available a matching donor PCB as this series of HDD is very new. Others that I have asked do not have spares either. Ordinarily I would use a matching donor to complete the diagnostic tests. However, at the moment these are are rare and those I have found are very expensive (offers welcome). Are there any suggestions for others tests that do not require a suitable match donor?

Secondly there appears to be some odd numbering from Seagate. On Ebay I found a Seagate Constellation ES.3 which shares the same model number and PN as this failed Barracuda XT drive.

How are Seagate numbering their HDDs? According to the Seagate website their current range of 4TB ES.3 SATA drives have a numbering as follows: ST4000NM0033. I thought the "DX" part in the model number denoted the XT range of HDD/SSHD

All the best,
John

New, Simplified Seagate Model Numbers:
http://www.seagate.com/files/staticfile ... 1102us.pdf

DX = Desktop Premium
DM = Mainstream
DL = Entry Level
LX = Laptop Premium
LM = Laptop Mainstream
LT = Laptop Thin
MX = Mission-Critical
NX = Nearline
VX = Surveillance
VM = DVR
VT = DVR Thin
FX/FM = Enterprise SSD

I guess "NM" would be Nearline Mainstream.

Yes, I would have thought that the any Constellation HDD would be marked with the 'Nearline' code. Which is why I was a bit confused by that HDD on eBay which is labelled as a Constellation ES.3 but has a ST4000DX000 model number.

I found the following:
----------------
800GB/platter Section (all drives under here use platters that can hold 800GB of data.)

Barracuda XT (7200RPM, 128MB cache?, SATA-600 interface)

ST4000DX000 4TB (5/10)

Constellation ES.3/Enterprise Capacity (7200RPM, 128MB cache, SATA-600 interface)

ST4000NM0033 4TB (5/10)
ST4000NM00533 4TB (Self-Encryption) (5/10)

Constellation ES.3/Enterprise Capacity (7200RPM, 128MB cache, SAS-600 interface)

ST4000NM0023 4TB (5/10)
ST4000NM00433 4TB (Self-Encryption) (5/10)
ST4000NM00633 4TB (FIPS Self-Encryption) (5/10)

------------

I am sure as these 4TB HDDs come in for recovery over coming months it will be come clearer how their configurations do differ.

Does anyone have spares for sale for my patient HDD, or other suggestions?

Fwiw from:
https://www.seagate.com/files/www-conte ... v-2012.pdf

MM = Mission-Critical, 2.5-Inch, 10K
MX = Mission-Critical, 2.5-Inch, 15K
NM = Nearline, 3.5-Inch
NX = Nearline, 2.5-Inch
FM = SSD Mainstream
FX = SSD Performance
