Question, after you swap the PCB boards, and then you boot up, does the BIOS detect the HDD?
...its true the new fix is good...thanx Vinicius, i too was having issues with the hyperterminal....i dont reccomend for others to persue it...though at the time it was necessary as the firmware was not available....this is what i did as did Vinicius
1. swap pcb boards on 2 like hd's ...flash the bad pcb with the new SD1 firmware
2. swap back the pcb's
voila !! full recovery from bsy hd with no LB0.
this post is for real, my brick is fully recovered.....i know you all paid for the rs232, as did i, but it is a real hard fix compared to doing it this way
as far as i know you do need to 7200.11's though .. .
Hello, I'm very happy now because I figured this out.
When you swap the boards the "old" board should boot the new drive with 0Mb. Since the disk is not made for that PCB. Will be normally detected on BIOS.
After this fireup firmware update. You'll some errors like Cylinder 0, assuming 63! Something like this. But just ignore and flash the drive.
After the power cycle reswap PCB's and use the old drive. It should be fixed from BSY and from LBA=0!
See details of what I've done in the Solution Thread.
I'm wondering if one can get away with not even attaching the PCB to the disk of the 2nd drive. The reason being is that when they make these at the
factory, they probably just attach the PCB to a test machine which flashes the PCB and runs electrical tests on it. This would be easier
to make these in mass and then ship a box of these to another site that attaches the PCBs to the actual disk that some other factory
site made in mass. Then both are run through another test machine to make sure the PCB and drive heads and platters work together.
Thus, for those with the PCB having LBA=0 and BSY, try just removing the PCB from the drive, attach the PCB to the power and
IDE/SATA cable, and then reflash with the new firmware. It'd be interesting to see if this works. Maybe the BIOS doesn't need to
detect them. This will also eliminate the possible damaging of the disk heads and platter of the drive that is incompatible since there isn't one.
The most that will happen is there is no spinup, 0 heads, 0MB/GB, 0 cylinders etc or this method won't work. The only thing that will happen
is that you are SOL!
The other possiblilty to bypass the BIOS is to attach just the PCB to an external SATA or IDE to USB adaptor cable (see sabrent adaptors or equiv)
and power cable ,then plug in the USB and flash thru the USB port. I'm not sure if one can flash thru the USB even if updating working drives, but
without any knowledge about it working or not, the only way to attain knowledge is to experiment.....and hopefully the BIOS is too stupid.
