Hard drive recognition

Sony / Vaio pcv-rz30cg
September 22, 2009 at 20:07:32
Specs: Windows XP
Ok, here's where I am to this point...
Hard drive crashed, leaving message: can't find NTLDR.
I give to a friend who says drive not spinning...he installs new hard drive and OS.
Meanwhile, I take old drive and find logic board on web...seller says mask ROM on platter must match chip on logic board...best bet is to swap mask ROM 8-pin chip from my original as chances are slim that they are same, and they must match.
Take new board, swap chips, install, and drive spins but BIOS can't see it. In fact, if I plug in both drives BIOS can't see either one--but unplug old drive, and new drive runs fine--this is all regardless of Master/Slave/CableSelect settings on hard drives.

Old drive is 150GB partitioned into 2 drives, new drive is 320GB

Machine is 2003 vintage running XP Home
Thoughts??? Questions???

It sounds like the old drive is shorting out the hard disk controller.

I think the drive would have to be spinning up in order to get the 'missing NTLDR' message otherwise the bios wouldn't see the drive and wouldn't try to boot from it.

In spite of seller information the board may not be a fix. Suggest you reinstall old board and chip, connect drive as slave and see what happens.

Good point about the drive DAVE. Yea, I tried that before I even bought the new board--doesn't work as slave. Trae has a good point also. I didn't personally confirm that problem, but what he says makes some sense. What seems odd to me is that nothing is recognized(at least on that cable) as long as the old drive is installed. I'm almost ready to install the original chip that came with the new board and see what happens. Of course Sony was ablsolutely NO HELP.
Thanks for the input.

Usually if attaching an additional drive causes both to not be seen it's a jumper problem but you said you tried all the settings. So I'd think either the board is incompatible or the problem with the drive is not the board.

I agree. To get to the NTLDR Not found message the BIOS would have needed to load the boot loader from the MBR first and that needs a working drive.

There is probably nothing wrong with the drive and it is more likely to have been a software error, not hardware.

Yes stuartS is right,your hdd is fine,ntldr is related to soft (os need this file to boot,) all you need to do is reinstall the old board and format hdd.
