BIOS recognize new hard drive as old one

I installed a new 500 GB SATA  and my system will not detect it but keeps treating it as the old one by it's SERIAL number and tells me it's disabled on boot up. What's wrong? How do I fix it?

I have unplugged computer after switching it off and changed post for it. It still recognize new hard drive as old one and tells me it's disabled on boot up. When I unplug hard drive it correctly notice I don't have one. Plug it back and it still recognize it as old one by serial number.

Can your BIOS handle the size and type of drive you are putting in? It may be it cannot properly recognize it, which is why it defaults to the old drive. I actually cannot think of any other reason and have not seen that before.

Did you alter the BIOS? There are routines around to patch BIOS to allow certain non-manufacturer hardware (wireless NIC's, for example) to be installed.

Are you certain the new drive is good (drives can come DOA).

size and type of drive is exactly the same as it's replacing. Didn't alter the BIOS. Brand new hard drive.

Do you have any capacity to test another drive in this system. I really have never seen a BIOS not properly recognize a good hard drive (my various systems or my clients, so that is a lot of machines). It sounds potentially like a bad hard drive and therefore not properly recognized.

Looks like it's a problem with detection. What causes old info to get stuck and not recognizing new hard drive after I unplugged it and started computer, turned it off and plugged it back.

Unless it is a strange BIOS, nothing prevents a good drive from being recognized (at least in my experience).

You can get USB hard drive carriers very inexpensively. Put the laptop hard drive into a USB carrier and check it in another computer.

What make of laptop?   You can use a USB hard drive carrier with any laptop.

It's 6 years old. I'm beginning to think the CPU is going. First time replacing a hard drive has gone wrong.

USB hard drive carriers. Is that the name I google to purchase?

It is possible that or the hard drive controller (part of the motherboard), or some other motherboard failure.

You can easily test the drive in another computer (including a laptop computer) with a USB hard drive carrier. Mine allows PC drives, laptop drives, IDE drives and SATA drives. I think it cost me $25 and now I have it for such testing.

But based on the last comment, it is vastly more likely that the computer has died than that the BIOS is remembering an old drive. I have not ever seen that happen.

Look for USB hard drive enclosures:

as an example.

Also, Tiger Direct and other like outlets usually stock them.

That's what I'm thinking after all I've done so far. I'll get the USB hard drive carriers to make sure. Thanks for your help.

Thank you and good luck going forward with both the drive and the PC.  ... Thinkpads_User

Actually the awarded answer is wrong. The reason the drive has the same serial number and the reason for this behavior is because your host machine is not talking to the disk at all. It is talking to the bridge chip inside the USB enclosure that is presenting a target disk.

The deal with the USB->SATA/ATA converters is that they are a protocol converter in addition to a physical interface convertor.   It makes an ATA/SATA device appear as a SCSI disk.

Data gets lost in the translation.  An ATA/SATA disk has a 40-byte field for a vendor/product ID, but the ANSI SCSI spec defines only an 8 char vendor ID, 16 char product ID.  For serial number, you have 20 bytes defined in the ATA spec, but in the SCSI spec, the serial number can be in a half dozen places, and length can be anything from 0 to 512 bytes long.

You have a cheap stupid bridge chip in there that isn't bothering to test health of the disk and present the proper SCSI Sense data that indicates drive failure.

The reason the serial number is the same is that this unit of yours doesn't bother to translate the serial number to the proper EVPD page.  You are getting some sort of hash.  

It is nothing to do with the motherboard. You have a bad enclosure and/or bad disk drive.

>>> You have a bad enclosure and/or bad disk drive.  <--- I allowed the possibility of a bad disk drive early on.

I assumed the controller circuitry to be part of the motherboard but have no way of knowing. I would also assume decent parts.

For almost certain, however, it was not the BIOS doing this. .... Thinkpads_User

So would you like the points?  I think I can arrange for that to happen if you so wish.

you keep the points. I'm just interested in explaining what the problem is and why.  (My company writes controller/disk/RAID diagnostics and appliance middleware and such, so this is what I do professionally)
