Hi,

I'm looking for help choosing the right kind of programmer for in-place programming the BIOS chip on PCB of number: BF41-00306A 00.

This is the board:

Also wondering if this approach is reliable. I prefer it to moving the bios chip as there isnt the risk of damaging the chip that way, but I have heard that sometimes it doesn't work.

Thanks,
Dale.

HM161GI is a Samsung Spinpoint HDD.

There are no adaptives or unique information on ROM.

If you need to replace PCB then you must only match ROM version or adapt the drive to recieve the donor PCB.

What is the problem with the drive ? Why do you think that you have a problem with the PCB ?

Does the drive spins at all with that PCB ? Can you get a terminal LOG ?

Maybe the ROM itself have problems like damaged FIPS. Why do you want to swap the PCB o start with ?

At this point I am not sure if it is mechanical or the board. Im just thinking to try a board repair first then later take to a data recovery centre if it doesnt work.

I dont know what a terminal LOG is and so far cant find anything about on it on the web.

The drive causes POST and shutdowns to take longer than usual, but isnt recognised in Windows Disk Management. It spins up when first connected and makes a couple of faint beeps and some normal sounding mechanical noises (like the heads moving around maybe, nothing nasty sounding), then spins down after about 20 seconds.

All websites which sell the board so far have said a bios swap is a must if you dont know the firmware, which I dont in this case because its not written anywhere on the drive . Apparently this is often the case with this drive.

Hello there !!!

First of all get a TTL adaptor like this - http://www.hddoracle.com/viewtopic.php?f=46&t=192

Plug it to the drive like this - http://www.hddoracle.com/viewtopic.php?f=116&t=189

Open your terminal software and power on the drive. Post the LOG that the drive makes to the terminal software.

It's not very likely for the PCB to be the problem. Most likely you have either bad heads or bad firmware.

I don't like the "faint beeps". I don't know what you mean. It might be the heads stuck to the platters ? Or even worse the heads scrapping the platters ? DO NOT OPEN THE DRIVE YOURSELF.

If the data is really important do not power up the drive again and send it to a professional data recovery firm.

For drives that you have a PCB problem and you need to replace it (like if you have a bad burned spot on the PCB and visible damage) you can allways buy an identical drive (same full model), read overlays from the donor, hot swap to the patient and write overlay from the donor on patient. Then apply donor PCB - http://www.hddoracle.com/viewtopic.php?f=116&t=1085

Also if the PCB is still working at some level you can read it's ROM using something like SHT DEMO - http://www.hddoracle.com/viewtopic.php? ... 1565#p8556

(you will need the TTL adaptor).

Regards and good luck.

Would this likely work with that drive:

My mistake, its one beep, and it comes just as it shuts down. It sounds electronic to my ears rather than mechanical.

I think that the mentioned TTL should work just fine, but i did never test one of those...

At any rate that "beep" might be related to heads parking when the drive stops to spin ....

Without a log it will be hard to say what is happening without opening the drive and you should NEVER open the drive outside a HEPA 100 clean room.

A serial port output log should provide a wealth of knowledge as to what's happening :-)

I have received the TLL adapter above. It has a CH340G chip.

Could someone walk me through how to get and output log using terminal software? I have tried installing various drivers using the device ID in device manager (USB\VID_067B&PID_2303&REV_0300)
but the device is 'failing to start', and nothing happens in the 'HDD Serial Commander' terminal screen when I connect it.

Im using windows 10.

If possible, I would try the adapter with an earlier version of Windows. Perform a loopback test by connect the adapter's Tx and Rx pins together, then type into a terminal program (eg HyperTerminal) and ensure that each character is echoed correctly.

Same problem with Windows 7. Cant get it to install.

Can someone recommend a driver for it, or another serial adapter like it which will work with the drive?
