Hi Guru Seagate 2TB when read and Write Rom with PC3000 SAP Error Ask for help and guidance. This hard drive has already been tampered with and I don't have access to the original ROM. The map of the heads in this hard drive is manipulated. I have attached the original ROM. Thanks and any help would be appreciated Model:ST2000DM001 PN:9YN164-300 FW:CC46 SN:Z2F

The bad SAP is at offset 0x246E8. There is a good copy at 0x646E8 in the second half of the ROM. You just need to write the good copy over the first copy. It looks to me as if someone has deliberately fiddled with this area (head map?): Good SAP Code: Offset(h) 00 01 02 03 04 05 06 07 08 09 0A 0B 0C 0D 0E 0F 00001670 01 02 03 04 05 05 00001680 06 07 08 09 Bad SAP Code: Offset(h) 00 01 02 03 04 05 06 07 08 09 0A 0B 0C 0D 0E 0F 00001670 01 00 01 00 01 05 00001680 06 07 08 09 BTW, the actual size of the ROM appears to be half of what you think it is, ie 512KB, not 1MB. |

CRC needs to be corrected... edit: it should be done by pc3k if you edit hd map using its dialog. |

If you want to work with Seagate F3 ROMs, forget PC3K. Use F3RomExplorer instead. https://www.hddoracle.com/download/file.php?id=8721 The SAP segment has a size of 0x5018 bytes. What are the part markings on your ROM? You still appear to be selecting the wrong ROM size.

I just restored your original SAP. I didn't meddle with the head map. That's up to you. |
