Using SD Tools.
Originally had corrupted ROM. Without going into detail, this drive has been in a couple different shops and original ROM chip has been lost. The whole approach to this drive should have been different but this is the current situation and hoping I can get a consensus from the group here as to if the data is lost or if there's still something else I can try to recover the data.

As some may know, this F/W does not have module 107 so ROM can not be regenerated by 'ROM regeneration'. Looking at the data in WinHex, it appears that modules 102, 103, 105, 109 have a different type of content in this F/W than in others that do have a module 107.
In WinHex, the content of the F/W modules at the very bottom of the F/W list labeled "content in ROM" looks like the content that is normally found in 102...109 so was thinking ROM could be rebuilt manually (and tediously) with these and WinHex, using ROM from my identical donor as a template and inserting the data into proper place.
Come to find out all F/W modules have been overwritten by another data recovery company with F/W from the identical donor so the "content in ROM" mods along with 102, 103, 105, 109 are not from patient drive.

With hot swap all F/W modules can be read/written (this is how the F/W was overwritten).

Any insight, opinions or ideas would be appreciated.

Well, there is a way around the ROM. But the big problem is translator tables. If you are certain that the native critical mods have been overwritten, then we do not have a good translator and we can't generate one from primary list, either.

So, data is likely n/r, unless the native modules/tracks can be obtained from the other data recovery. I hope they saved them.

From my understanding, the overwriting may have been stopped halfway through the module list.
IF the native critical mods are OK, it sure wouldn't hurt to try generating new translator info.
Can you suggest a method to attempt/do this?

Sent pm.

Request for ROM data for WD30EZRX - 00MMMB0 DCM HARCHV2ABB I do not have a solution for this particular problem, but I have a question about this same model hard drive but a slightly different situation. It is a 3TB Western Digital WD30EZRX - 00MMMB0 DCM HARCHV2ABB. The drive is always in a busy state and cannot be recognized on any of my imagers or Salvation Data WD HD Doctor. I removed the pc board and placed it on the WD HD Doctor and PC board still stays busy. I ordered a replacement pc board and the drive now starts ok and goes to a ready state but it needs the original ROM data from the original ROM IC to ID the drive correctly. I then swapped the ROM IC from the original pc board and now the replacement board is always in a busy state. The problem is the origial ROM IC is defective. Can the original ROM data be regenerated or uploaded to me so that I can overwrite the functional ROM IC from the donor pc board. Any help or thoughts would be greatly appreciated.

Could you upload it?


If you install the PM2 (Power Up In Standby) jumper, does the drive still remain BSY?

I've yet to see a corrupted ROM in a Dragon drive, and this thread has two of them?

Ditto. Maybe SD has problems reading this drive since they use the same settings for all ROYL drives....
