hi this hard drive was on my old computer.I took it off the computer and stored it away for about a year. When i reconnected it to the Motherboard the BIOS wouldn't even recognize it. It worked fine before i put it in storage. I've tried connecting it to many different computers, but its still the same. None of the BIOS recognize it. The Drive does not spin up.but the DSP chip gets slightly warm to the touch.What could have gone wrong?

Anyway I assume this is a controller card faliure(since the bios doesn't even recognize it and because it used to work fine before. ) So if I am to switch the controller card on this, What Numbers do I have to match on the other drive?

My Drives details are:
Model = 4D040H2
HDA = 22A
PCBA = 05A
unique = 11A
Code = DAH017k0
Cylinders = 16383
Heads = 16
Sectors = 63
LBA = 80043264
Drive S/N = D25Z88FE

Mfg Date May 2002 Made In Singapore.

Other Codes:
4D040H2220511
K,M,B,C

Thanks for your time and effort in reading this.

Any 4d040h2 pcb with DSP chip is going to work with you drive .

Just change the pcb if the board is heating up. U can get one from these guys in Canada

I am working on a similar HDD from Maxtor.

I assume this is an IDE ATA. There is the 40/80 cable thing, and of course primary (master/slave), secondary (master/slave)
Q)check the jumpers, are they set according to the cable you are using?

As a fall back just set the jumpers for Master (not cable select) and use a 40 pin if you have one. If you only have a 80 pin, be sure the the P1 connect is on the MOBO and the P3 is the on the HDD drive. If you need to connect to a CD or DVD then use the center connector P2 and be sure the CD jumpers are set for slave not cable select.

I initially forgot all that and was stumped until I remembered that crap. Hope it helped.

yes It is a IDE ATA drive.



On my new Computer I have only SATA drives. Mother Board Does have a IDE cable but there is nothing on it. I have the 80 pin cable. But I even tried connecting it through a USB to IDE cable.Still no luck. So it cant be the connectors.

i have no Idea what you mean by


Anyway thanks a lot fro your reply and your time.

From everything I am reading and researching I see this message stated and re-stated often: You can't assume its bad just because one method is not working.

One thing I do with any electronics project is to get nostalgic. Meaning to use the old equipment with the old applications, the old drivers, etc. In your case the first thing I would do is connect it to the IDE interface on the MOBO in a Primary Master the way the device was intended. If it doesn't spin up don't worry, use MHDD and reboot then see if MHDD can see the drive.

lemme know what happens

In the good old days (1980's), I had to specify the Cylinders/Tracks/Heads in the BIOS manually. There was no auto-config detection. Some old BIOS did not support drives above 2gig, so I "fooled" it by reducing the cylinder count to get the total formatted size to be below 2gig for large drives.

As an example if the drive was 3gig and had 64,000 tracks, I told the BIOS it had only 45,000 tracks (these numbers are only an example, I'm not sure of the exact numbers I used), so the drive now became formatted 2gig.

I had to write the C/T/H configuration on the drive itself with a marker pen because whenever I updated a motherboard for a customer, I had to manually set the exact same C/T/H numbers into the BIOS for it to be recognized and to work.

This is because when you create a partition with the original BIOS setting, the heads and tracks containing the drive info has to be recognized by the BIOS so it can read the drive data and the boot track.

If you can remember the old C/T/H settings, try to manually enter it into the BIOS. If you don't remember, it's futile because without it, the drive will never be recognized.
