    Where is EEPROM in Samsung HM060HC HDD?

    Hi, I have a Samsung HM060HC that gets recognized by BIOS as a "CAMSENG HM 6 HC" drive at 60GB
    Windows sees just a 5.91GB RAW partition...

    I bought a new BF41-00100A PCB for it and I was not expecting the swap to work, because I've tried this in the past and it did not...
    Drive is not even recognized with the new PCB...

    But I can't identify the EEPROM, I know I need to transfer it to the new PCB I bought. I guess it's in either the Marvell chip or the TLS2502
    I found also a service manual, it's not for the exact same drive but very similar, but the block diagram showing the "Internal flash ron" (sic) just has me scratching my head...

    I attached some pictures of my drive, plus the service manual...

      my guess is the 88I6525, since it has the internal rom, but from the sounds of it, it seems like the chip is dead. I would be wary of moving the chip over and having the same problem appear on the new board. It also looks like a BGA chip.

          Yea the Marvell is a BGA chip.
          I've had a similar issue with another HDD, bought a new PCB and then it was no longer recognized at all.
          And then when I transferred the original EEPROM to the new PCB the drive just behaved exactly like it did with the original PCB, so the error was in the EEPROM

              Try to ask over at HDDGuru, seems to be a few smart guys over there - they do a lot of work just like this.

                  Samsung 225MW EEPROM bootloop
                  by Jacksoft
                  Hi all,
                  I got an old Samsung 225MW TV with BN41-00825 motherboard.
                  Since the TV has a buzzer when it starts it makes a beep. The main problem is that the TV goes in a sort of bootloop and beeps every 2-3 seconds.
                  So I attached the VGA UART cable and read the debug data using a RT809H programmer:


                  According to the Service Manual all the voltages looks good, so I made a backup of the internal flash and all the EEPROMs (1 Settings + 3 EDID) and cleaned the EEPROM.
                  Now the TV boots but it's stuck on VGA. If I try to change the source it goes to TV, restarts...
