Hello, I have ST500LT012-1DG142. The spindle does not start and the drive remains in BSY. Terminal said only: Code: Bad CRC Seg:0x06 Boot 0x10M I've read the ROM and PC3k states that ROM images contains critically damaged objects [RAP]. I further checked the ROM information: Code: Parsing container segment....... Flash ROM image Segment: BOOTFW_DIR Parsing segment....... BOOTFW_DIR End parsing segment...

I also checked the PCB number and it also matches. The only unusual thing is that this ROM is 1 MB. All the others I've seen of this model are 512KB. It looks as if in this drive the ROM has two copies on the chip, but both are identical. Do you have any idea how to fix this ROM? I've run out of ideas. |

The ROM consists of 4 parts. There is a single-bit error in parts 2 and 4. Code: Offset(h) 00 04 08 0C 00064230 00000000 00000000 00000000 00000000 00064240 00000000 00000000 00000000 04000000 ^ 00064250 00000000 00000000 00000000 00000000 Code: Offset(h) 00 04 08 0C 000E4230 00000000 00000000 00000000 00000000 000E4240 00000000 00000000 00000000 04000000 ^ 000E4250 00000000 00000000 00000000 00000000 Edit: I see that @E123 has already repaired your ROM in your other thread. |

What I'm wondering is how this error appeared in both copies (in both places). How did you even find this wrong place? I used the your program to look for a single error, but it did not indicate this location. |

If you mean F3RomExplorer, that program was written by @E123. Ace's parsing results suggested that there were 4 parts. I simply searched for "csiD" headers in my hex editor. ("csiD" is "Disc" in little-endian) |

STROMfix_2 attempts to detect all possible single-bit error candidates in a corrupt ROM segment. You first need to extract that bad segment. The tool does not work on the whole ROM. |

How did you actually target the right segment? PC3k indicated a problem in RAP. From what I can see, the error was much further (at 64230). RAP segment ended at about 25k offset. |

The ROM is actually a 512KB part, not 1MB. (It doesn't make sense for 2 errors to occur at the same location in each 512KB half of a 1MB ROM.) There are 2 copies of the RAP within the first 512KB. The first copy is OK, but the second copy has a SBE.
0x5C180 - 0x6558F I just compared the first half of the 512KB ROM with the second half. BTW, the free version of F3RomExplorer only detects the first half of the 512KB ROM (256KB), so it doesn't detect the error. |
