How to fix the motherboard does not recognize the hard drive

When the pc boots up and doesn’t acknowledge the exhausting drive, making the machine unable to enter home windows, or the pc boots and stops on the DOS display and says ” Reboot ans choose correct boot machine or insert boot media in chosen boot machine and press a key ” or ” Disk boot failure, insert system disk and press enter “. These are the messages associated to the pc exhausting drive. Train you the way to repair the pc that doesn’t acknowledge the exhausting drive.

Within the article, I solely present you the way to repair the mainboard that doesn’t acknowledge the exhausting drive. So it is totally different from the ghost brothers cannot entry home windows, home windows errors, mbr file errors on the exhausting drive… The errors about this software program I’ve talked about. To know if the pc acknowledges the exhausting drive or not, you’ll be able to have a look at the DOS display when booting or enter the BIOS to see if the exhausting drive identify is there.

On the mainboard, the pc makes use of two interfaces for the exhausting drive, which is the IDE ( Built-in Drive Electronics) interface utilizing a 40-pin cable and the 7-pin SATA (Serial Superior Know-how Attachment) normal. The SATA normal has a sooner information switch fee, and most of the people use this normal at the moment.

1. For SATA drives.

Examine if boot from exhausting drive is chosen in BIOS. Usually, for those who do not choose it, it is going to robotically boot the exhausting drive. However there are some instances the place you select in addition from the CD/DVD drive if you’re leaving the disc to hearken to music, or be taught English through which it won’t enter home windows.
On some older motherboards, there are each IDE and SATA interfaces. If  choose the flawed SATA mode, it won’t boot. See if SATA mode is AHCI or IDE, if AHCI is on, select IDE to obtain.
Attempt utilizing one other exhausting drive, or carry the exhausting drive to a different machine and see if it acknowledges it. If obtained, we proceed to verify.
Attempt a brand new SATA cable and check once more.
Attempt one other energy provide, many energy provides with voltage drop can nonetheless begin the pc however not sufficient voltage for the exhausting drive.
Reload the BIOS to verify if the machine acknowledges the exhausting drive.
On the mainboard, the SATA port has 7 pins, of which there are 3 floor pins and information transmission and reception pins. These pins undergo 4 small filter capacitors after which into the Southbridge chip.

• Use an ohm meter to regulate to the X1 ohm scale after which measure the continuity from the pins A+, A- and B+, B- to search out the filter capacitors related to those pins on the SATA port.
  Proceed to take away these 4 capacitors or change them with one other one and verify if the machine has obtained the SATA exhausting drive.
  Steam once more or change with one other southbridge chip. Consult with the article: Substitute chip male .2. For the IDE exhausting drive (this drive is presently hardly ever used).

  Ensure that the exhausting drive continues to be in good working situation by bringing it to a different machine to strive it, or use a very good working exhausting drive to connect it.
  Enter the BIOS restore to default ( Load Bios setup default ) and verify if the machine has obtained it.
  Attempt a brand new IDE cable, and take a look at a brand new supply.
  See when you have set the jumper to set grasp mode? On the IDE exhausting drive, there’s a jumper to set grasp (major), slave (slave), cable choose (elective mode,  major when there may be 1 drive and secondary when there are 2 drives). Older motherboards set incorrectly won’t acknowledge the exhausting drive.

• 

• Examine the IDE slot on the mainboard to see whether it is correctly connected, damaged or soldered.
  Lastly, proceed to solder the SIO chip pins (the IO chip manages the IDE slot, the male chip manages the IO chip). If not, proceed to switch the IO chip for the mainboard.These are instances the place the pc doesn’t acknowledge the exhausting drive as a result of a BIOS setting error, a soar setting or an error within the exhausting drive administration chip. Wishing you success.
