Hi everyone!
I have this Toshiba 14TB drive MG07ACA14TE

Attachment:

One day powering on the drive. The drive spins fine. Doesn't have any clicking sounds. But doesn't show up on PC
Upon testing in PC3000. The drive is stuck in BSY

I think it might be something wrong with either the PCB or the ROM
However it has 4 ROM chips and i don't know which one is the main one. Or what are they for
The Original PCB label is G0022A

I got my hands on the Donor Drive. Also MG07ACA14TE however the PCB labelled G0044A

4 DONOR DRIVE BACK.jpg [ 816.7 KiB | Viewed 963 times ]

So i got my hands on a Spare PCB G0022A as well

Attachment:

5 DONOR PCB BACK.jpg [ 1.2 MiB | Viewed 963 times ]

Can anyone help me identify which is the ROM chip?
I will also provide with Original PCB ROM file, Doner G0044A ROM file and Doner PCB G0022A file. If anyone can help me out check the ROM files. Find the difference and fix the Original PCB ROM. Please let me know.
Many thanks!!

I can extract the CPs from the ROM and test their checksums, at least in earlier models.

The additional ROMs appear to be for power loss data protection, although I would have expected to see a bank of backup capacitors.

I think it's IC4, probably on both PCBs.

Yeah, you are right

I will read the chip and upload it here tomorrow. Thanks for taking a look for me!

Your donor is an MN08, not MG07. :-?

backup caps are absent coz drive can recover sufficient power from rotating spindle i think.

There is a large unpopulated location for a backup capacitor, but there are several smaller ones in parallel.

I got the Original ROM and the DONOR PCB ROM Read out. Please take a look!
Many thanks Fzabkar!

This model has a new architecture. The CPs, assuming that's what they are still called, appear to begin at offset 0x100000.

Code:

Offset(h) 00       04       08       0C

001000A0  FFFFFFFF FFFFFFFF FFFFFFFF FFFFFFFF  ÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿ

They appear to have a 16-byte header, a body of data, and a 32-bit checksum.

This appears to be the serial number:

Code:

Offset(h) 00       04       08       0C

00100040  5345524E 00000000 00000000 0C000000  SERN............

          ^^^^^^^^^^^^^^^^^^^^^^^^^^ ========
                data                 checksum

The size dword reflects the size of the data, not the whole CP.

The checksum is calculated so that the sum of all 32-bit little-endian dwords, including the checksum dword, is 0x00000000.

I still have an ongoing medical emergency (not mine), so it will take me some time to write a new tool to extract and verify the CPs.

That said, doesn't the fact that the drive spins up suggest that the ROM is OK? Surely if the ROM was bad the firmware would produce a no-spin symptom?

The area from 0 to 0xFFFF appears to be reserved for a flash loader. The checksum dword is calculated so that the sum of all 32-bit little-endian dwords, including the checksum dword, is 0x00000000.

Code:

Offset(h) 00       04       08       0C

I haven't started analysing the patient. I've only looked at the known good donor to establish the structure and the checksums. I still need to do more work. Alternatively, you can check those same areas with a hex editor. I use HxD.

This new firmware architecture is nothing like the old one. I can't just modify my current Toshiba ROM checking tool. I need to write a completely new tool.

All the CPs have a checksum of 0x00000000. Most of the other components which I extracted also have a checksum of 0x00000000. Those components which don't have a zero sum in the patient also don't have a zero sum in the donor.

One big difference is that the patient has this stuff but the donor is empty in the same area:
