Hello,

I have a Hitachi HDD, #13G1583, MLC# DL1175, serial XGGLNE1M, board part number 0A26798 Da1188A Xzz609 54VZ. Pics at bottom.

Basically, I removed this from a notebook in order to do a backup (oh, the irony, as you'll see). It was working fine just before this. It was getting pretty full and I needed to clone it to a larger HDD. For some reason immediately after this, I could not get it to read in the desktop where I do cloning, and no enclosure would see it either. I tried every jumper setting on my 2.5" to 3.5" adapters after this and tested known good drives with every adapter and enclosure I have (the known goods were fine). Frustrated that this drive wouldn't be seen in anything, I finally put the drive back in the notebook thinking, "Well it worked in there, I'll just put it back and see if I can just get an image from there", and then nothing. The notebook acts the same whether there is no drive there or if the drive is installed. No sound from the drive, no spinning, just nothing.

So, I'm hoping someone has this board available, but I'm definitely wanting to hear your professional opinions on whether you think this is what's needed, as I have almost no experience with board swapping.

Also, maybe some insight into what might have went wrong would be great. I'm really stumped as to what could have happened there.

Hope you can help and I very much appreciate all you might be able to offer.

Thanks very much!

-Rob

Hello,

My wife and I haven't yet decided what to do with this drive yet, but just for curiosity's sake, since I finally got the correct size screwdriver bit to see the component side of this PCB (I had to at least know if something burnt out, and I don't see anything), what IC would I actually be taking from this and replacing onto a donor PCB? If it is indeed the PCB at fault, is this most likely all I'd have to do is swap the IC?

I'm a bit worried because they are all surface mounts, with only one little 8-pin IC even solderable with very specialized tools.

Edit: OK, I see 2 small 6-pin ICs too.

Hi,

When you get a working donnor PCB, you need to swap the rom chip to the donnor PCB, it is in U6, and have 8 pins.

Thanks
Eric

100% sure you have to either swap NVRAM chip or read it directly and rewrite the donor PCB.

Safest method would be to read/write it. If you have good soldering equipment and practice, then no problem.

Otherwise, safer to read chip and re-write it (many ways to do this even without SD and ACE tools).

Hitachi has different starting point of SA for different drives so original location is a requirement to access data.

Good luck.

Hi Folks,

I swapped the bios tonight with a donor board, and I'm afraid the drive is still not recognized. As far as I could tell, the desoldering and resoldering of the bios chip went perfectly, except that it doesn't work. Any ideas?

If drive has been loaded with info almost to a maximum capacity it most likely created physical damages on a platter surface.
I suggest you take it to a pro for accurate diagnostics and then decide what you want to do with it.

Success!

I swapped the donor board's bios chip back to the donor board just to see if the disk would spin. It did. I put my bios chip back on the donor board, and it spun too and was recognized. No clue what was wrong before, as all connections checked out. Man, am I glad I was recommended to try that!

The drive is cloned and back I'm back in business.

Thanks to everyone for their help! I appreciate it so much, I could never put it in words. Thanks a million!

Nice job, very glad to hear that you get your data back ^^

We tested each PCB in good working condition before ship them out.

Yes, Eric sells quality product and was amazingly helpful. I had a little trouble with the board at first, but that was my fault. I never doubted you, Eric! I was sure the whole time it was me that did something wrong. Wink
