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
