SIR

as you know this is SAS hdd

i want to repair, i have MRT sata support

can you advice to detect in repair utilities

thanks

Do you suggest connecting a SAS drive to a SATA controller? Looks like you've invented a new specification... Try contacting the MRT lab for support. It will be very interested to know their answer.
If you don't make idiotic suggestions, then some WD drives with a SAS interface can be restored using T-REX and a compatible SATA PCB. I practically did not do this, I only heard about successful experiences. I can only note that after such a repairing the disks will only work with a SATA PCB.

Here is an interesting thread where someone used a SATA PCB to access a SAS drive:

https://groups.google.com/g/datarecoverycertification/c/ZM1Yghm9rV4/m/5B5fT5lZEAAJ

I suspect that the drive in that thread began life as a 2TB, 6 head, SATA model, and was subsequently recertified as a 3 head SAS model.

My theory:

The SATA drive that was the basis for the hotswap was a 2TB model, presumably with a head map of 0b0000111111. The recertified SAS drive has a head map of 0b0000111000, but originally it was a SATA drive with a head map of 0b0000111111. This means that the patient drive originally had an SA on physical heads 0 and 1. Those are the heads that are being dumped by the 2TB SATA donor after a hotswap. The invisible SAS firmware modules are in the SAS SA on physical heads 3 and 4.

Does this make sense?

Hi

Anybody here please advise sata pcb , To repair this sas hard-drive on TREX.

THANKS

Show us a clear hi-res photo of the PCB so that we can identify the ICs. Also, please dump the ROM. We will need the adaptives.

I found this photo, but it is useless:

I'm wondering if 2060-771642 would be compatible:

https://s.turbifycdn.com/aah/yhst-14437584971410/91710995-19.gif

It has a SMOOTH L7251 3.1 motor controller. The HDA pinout looks similar, but we would need to verify the supply pins for the preamp.

Also, please dump the ROM. We will need the adaptives.

For what purposes do you need a ROM? What are you going to do with adaptives? Do you know how to convert the service area from Arch7 to traditional ROYL? All you need is a HDA from Arch7, a compatible SATA-ROYL PCB, a compatible “packet” and a working T-REX shell. I've heard that an important criterion for compatibility is the wedge/track ratio.

[fzabkar]

In that other thread I was able to find adaptives in the SAS ROM. I was hoping to import those SAS adaptives into a SATA ROM, and then use a SATA PCB and loader to gain access to the SAS SA and dump the tracks.

thanks

hi

this SAS PCB 771676-002

i think no ROM ic, the pcb is ROM-less

expecting HELP

I don't know how the terminal works on SAS PCBs, but if it works the same way as SATA, then choose a 2TB Green SATA family (if necessary) and dump the ROM via the terminal port using your terminal adaptor.
