Hi all.

On a HP DV4-2145DX, I'm getting a Hard Disk Not Exist. The drive is new, and works in my USB enclosure on another system. It's partitioned and formatted, but not recognized by the DV4. The original Toshiba 320GB HDD was fried, and this replacement is a WD Scorpio Blue 500GB. It is my friends machine. He installed the new drive and got stuck when it wouldn't boot. I've thought it through and here's what I've come up with and where I'm stuck. Any help appreciated!

Possible issues:
1) The BIOS. It doesn't seem to have any visible HDD settings, so...can't tell if there is a config issue. It for sure does not recognize the drive. How to tell if BIOS settings are the problem?

2) The mobo. The drive does not sound like it is running at all, so may not be getting power or commands. I do NOT have another 2.5" drive to swap in, but again, this drive is good in my enclosure. How to rule out the mobo?

3) the mobo HDD connector. Looks like the connector is cracked and pulled apart a few millimeters (likely due to the ridiculously tight fit of the HDD chassis and undue force applied in the removal/install). The pins all look good, but maybe there is a broken conductor or solder joint? How to test?

4) The new HDD speed. Saw on another forum that somebody had to slow down their new Seagate HDD in a DV4 by putting in a jumper. WD seems to have the same pin assignments, so I tried the jumper but no joy. I need to dig further into the specs on this if the BIOS and mobo are ruled good.

Simple right? :-)

thanks for any help!

Mike,

Did you ever figure out your hard drive issue? I have the same problem with my HP DV4 2167sb and cannot figure out what is wrong. It will not recognize the hard drive. It freezes at the HP logo screen (press F2 for startup). It still freezes at the HP logo screen even when I have a Recover CD in the CD drive or a bootable USB external hard drive.

It will only boot from USB external hard drive when the internal hard drive is removed.

I've tried all the usual HP suggested solutions and nothing works. I've even flashed the BIOS with the original bios and the most current bios.

Rather than using it as a doorstop, I'm using Linux on a USB flash drive until I can find a solution to the internal hard drive problem.

Anyone else have any suggestions
