Hello all,

I got this ST1000LM024 that isn't spinning. Any other PCB would spin the drive. I suspected the failed ROM, so I moved the ROM from the patient to a perfectly working PCB, and now that PCB is not spinning the drive. I pulled the ROM dump, and then several other similar ROMs. I figured that the ROM signature is corrupt, so I've corrected it. Still not spinning. I am wondering if anyone can shed some light on this issue. Would like to get it going, but stuck at the moment. Haven't had Samsungs in a while.

Thank you in advance.

I'm no HDD guru, but I have written a tool to parse Samsung ROMs. If you upload your ROM dump, I'll have a look.

can be problem with fips, or not native pcb can also fail on preamp ID before spinning up...

Haha. Ironic. My nickname. It's been a looooong time since I touched any data recovery projects. Still have the tools and just trying to help a friend.

I appreciate your help! The file is attached.

Somebody messed with the boot block header. I have restored the original 16 bytes.

Bad ...

Code:
Offset(h) 00 01 02 03 04 05 06 07 08 09 0A 0B 0C 0D 0E 0F

00000000  23 65 80 0C 00 00 00 4D 01 00 00 4D 01 00 00 B0

Good ...

Code:
Offset(h) 00 01 02 03 04 05 06 07 08 09 0A 0B 0C 0D 0E 0F

00000000  23 65 A4 0E 00 00 00 4D 01 00 00 4D 01 00 00 D6

What did you mean by this?

If the drive still doesn't spin up, examine the terminal output.

AFAICT, these are the supported preamps:

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 segment or SERVOTBL segment, 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.



Calculating ROM checksums ...
Checksum for 0x000000 - 0x03FFFF = 0x8655
Checksum for 0x040000 - 0x07FFFF = 0x3F1E
Checksum for entire ROM = 0xC573

Extents reported by FLASHTBL header = 0x000000 - 0x0340FF
Extents reported by SERVOTBL header = 0x034100 - 0x03FFFF

Checksum from 0 to end of SERVOTBL segment = 0x8655

Checksum (adjusted) from 0 to end of SERVOTBL segment = 0x7D53
Checksum (adjusted) from 0 to 0x41FFF = 0x0000

(adjusted for FIPS and penultimate words in SERVOTBL)

I knew you were a genius. Thank you so much! I will try this and report back.
Thank you 10000 times!

Hello,
I tried the ROM you edited, but it didn't spin the drive either.

I just re-read the original ROM from the drive once again (attached). This is not modified.

I am wondering if you could please take a look at it once again.

Thank you so very much!

I can't recognise any problem with the original ROM. You need to obtain a terminal log.

There is a section at 0x7F000 - 0x7FFFF which I don't understand. I don't know if that has any bearing on the problem (I expect not).

I'm also not sure where the PUIS flag is located in the FIPs for this model. I believe PUIS is disabled (0xFF), but I can't be certain.

Sorry if I'm stating the obvious, but are you aware that there are two different PCBs for this model?

Thank you! Yes, I moved the ROM from the patient to the donor PCB using the same model. I will double-check again just to be certain, but I do believe I checked that.

I will try to get that tomorrow. Thank you so much for trying to help me. I truly appreciate that.

Left is the donor, right is the patient.
Wasn't able to get the log file, but will try again tomorrow.

Thank you again!

Measure the voltage at the 5V TVS diode. There is an inductor between the diode and SATA +5V. Samsung's soldering has been affected by dry joints in other models, so this would be something to check.

Also measure the voltages between ground and the 2R2 and 4R7 inductors.
