Why are you replacing the hard drive.....maybe the problem wasn't the hard drive?

There are two pairs of pins on laptop IDE hard drive headers that do not plug into the laptop's connector. One pair you install a jumper on to set it to Slave, the other pair you install a jumper on to set it to Cable Select.
The drive does not come with a jumper for that, unless it was previously installed in a system that had two drives.

If there is only one place you can install a hard drive, the drive is set to Master when there is no jumper installed, and it should be detected fine by the bios if there's nothing wrong with your laptop or the drive.

If there are two places you can install a hard drive
- if you have only one hard drive it should be installed in the primary bay and it needs no jumper

- if you have two hard drives installed, either
- one should be installed in the primary bay and it needs no jumper, the other is installed in the secondary bay and it needs a jumper to set it to Slave
- both drives need to be jumpered to Cable Select

thanks for the help tubes and wires, i am having the same difficulty because i am used to a desktop computer and someone told me that you don't need jumper pins for a laptop, but that might be the problem. since the laptop didn't come with jumper pins, i'll have to try to find some somewhere.

The pins for the jumpers are on the hard drive itself, not on the laptop's wiring or hard drive connector, and they are present only when the hard drive is IDE

Read response 2 again.
Most people who have a laptop with an IDE hard drive can only install one hard drive, and in that case no jumper is needed on two of the pins on the hard drive.

If you are having (a) problem(s) that seem to indicate to you that the laptop is not detecting the hard drive, describe your problem(s).

In most cases, if the laptop does boot from the hard drive, the bios IS detecting the hard drive but something else is wrong.
