Hello,

I am looking for a Rom to Samsung HM321HI ver. 2AJebq4
Does anyone have a working ROM?
I add the original rom from the PCB.

Regards,
Michael

What error do you see in terminal?

Here is the output of my ROM analysis tool:

Code:

Note 1:  The address range of affected module may conflict with another module,
          in which case this is probably a false negative.

Note 2:  If this module is the FLASHTBL or SERVOTBL, then this is most likely
          a false negative.

Note 3:  This may or may not be a genuinely BAD module. Examine the checksum
          of the first half of the ROM. If 0x0000, then module is probably OK,
          otherwise it may or may not be bad. Also examine the "adjusted"
          checksum, if applicable.

Note 4:  The address range of the module is outside the limits of the ROM.

Dear fzabkar,

I did not connect to the terminal. Drive does not spin.
I tried to copy the FIPS section from a working rom but it does not work.

ISTM that the FIPS size is 2048 bytes, not 4096.

Code:
Verifying Samsung SpinPoint ROM:  2AJebq4M_d43.bin

Checksum of Boot Block header = 0xAE  - OK
Checksum of Boot Block (Actual/Expected) = 0x672C / 0x672C  - OK

Searching for FIPS block (expected checksum = 0x0000) ...

Found FIPS text string at 0x003000
Checksum for 0x0400 byte FIPS block = 0x3A94  - BAD
Checksum for 0x0800 byte FIPS block = 0x0000  - OK
Checksum for 0x0C00 byte FIPS block = 0xFE00  - BAD
Checksum for 0x1000 byte FIPS block = 0xFC00  - BAD

Possible 0x0800 byte FIPS block at address 0x003000
