To any kind soul that can help me repair the 4 HDD that is bricked...

I am a total newbie in this software, but I tried to read the ROM of the DFL tool on 4 western digital hard disk and the device said "ROM read success", so when I tried to write the ROM that I have just read out from the tool, I was being prompt with "ROM deep test error" (or something like that) and something about the "ROM being of a different length , would you like to force write" and I just ignored the warning and proceed to write the ROM. Now whenever I plug the HDD into the DFL tool, the 2 lights that are flashing are "DRD" and "ERR", the HDD is not even spinning anymore, please help SOS...

Q: why have you tried to read and write in the first place ?
Q: what's the initial problem with the drive ?
Q: do you have any other tool beside DFL ? (PC3K, external programmer)
Q: can DFL access the PCB using terminal ?
Q: would you mind upload the ROM here ?

If drives are WD you can do a hotswap and rebuild ROM from SA. Look in DFL forum, there should be a manual how to do that. Do not try that on client drives but two known fully working ones for practice first.

Do not ignore warnings in DR-tools, most time they are right and you can trash a drive with them fast (ie defect list erase, ...).

Best regards,

Did you read DLF WDII manual before you start bricking hard drives?
What was problem with those WD's.

I would start to check if the WD drives that you have bricked have external ROM and if so you can use external programmer to write the ROM that you saved back to it.

Do you have something like WD-UCommand tool ? - http://www.hddoracle.com/viewtopic.php?f=22&t=217 Or even better something like PC-3000 ? If so you can write wrom back by TTL. I don't know if you can do that using DFL but i think not.

Why did you READ the rom and then WRITE IT BACK ? Did you write back the same ROM file created by the READ ? If so then DFL messed it up somehow. It shouldn't happen. If you read the ROM and then you write it (the same rom) then there shouldn't be any change in drive behaviour.

Maybe you need better tools ? Maybe there is a bug on DFL ?

The WD HDD did not have any problem at the start until I tried writing its original ROM back to it.

I really don't get it, if the drive didn't have any problem in the first place, why would you try to rewrite the ROM
I really hope it doesn't belong to a client
Regardless what is the 2 files (I.e. which one is the problematic) ?

Both ROM are problematic just from different HDD. I was just trying to explore the different features of the software.

I can't check your ROM now, but This ROM is the same ver. as your ROM_WDC WD5000LPCX-00VHAT0.bin.txt just transfer the adaptives
the question is if you have access to drive to flash another ROM I.e. using TTL or external programmer.
Regarding the other one - like I said - I can't check it now, and I wasn't able to find it either.

I would say that either the user have done something wrong and flashed the wrong ROM file to the wrong PCB or DFL have some issue/bug and wrote incorrect data to ROM chip/MCU embeded ROM by VSC bricking the PCB.

Now the question is how to fix it!

If the PCB have external ROM chip you can re-programm the backup back to the chip with something like this :

http://www.hddoracle.com/viewtopic.php?f=117&t=865

If ROM is embeded on MCU you can use something like this :

http://www.hddoracle.com/viewtopic.php?f=22&t=217

Or you can use PC-3000 if you have it ....
