Author: During POST or Power On Self Test, computer BIOS attempts to get information regarding all of the devices attached to your computer system. After examining the processor and primary memory (RAM), it checks for the devices like hard drive, CD ROM etc and shows them with messages on screen like ‘Found Primary Master’ and ‘detecting IDE drives’ etc.
-> POST (Power On Self Test) is the first thing done by BIOS when your computer first boots up. POST is an in-built diagnostic program, which examines the hardware of your computer system to make sure that everything is available and working properly.
Many times, the BIOS of your computer just declines to recognize the hard drive, basically makes it unusable- there is no way in which your operating system will recognize the hard drive if BIOS can not. Let’s observe why all this happens.
The most frequent reason of this problem is a badly connected or loose data cable. You should first ensure that data cable is properly plugged in, both into the motherboard as well as the hard drive.
The same thing goes for the power cable, so you should check it as well. You should also make sure that red lines on data cable and the power cable are contiguous to one another.
Once you have ruled out the cable problems, you need to check out the jumper settings on hard drives. If two hard drives are attached to a port, ensure that one is set as masters and other as slave.
Next, ensure that the hard drive controllers on motherboard are not disabled. These hard drive controllers control the IDE devices and without them BIOS could not detect the hard drives.
If any of the above mentioned methods does not work, you need to search for a data recovery expert to cure your hard drive. It seems that hard drive has some internal problems, which can not be cured without opening it. And you are not recommended to open your hard drive at your own.
Data recovery experts are highly qualified and trained professionals, who know all ins and outs of the hard drive and are able to fix most of the physical hard drive problems. To ensure absolute and safe data recovery, always go for the experienced and reliable data recovery company.

If you have considered purchasing a used laptop computer you might first want to review the following step by step evaluation process to ensure that you get a good quality used laptop computer.
1. Find out what external hardware is included with the computer. At a bare minimum, the laptop computer will need a power cord. Other options that might be included are an external mouse, keyboard and floppy disk drive. Additional hardware offerings could include a microphone, speakers, printer, scanner, external wireless card and battery.
2. Find out what internal hardware is included with the computer. The most popular internal hardware component is the internal wireless network card. Other internal hardware components include things such as a video card, DVD drive, CD Rom drive, and a sound card.
3. Before you even consider purchasing a used laptop computer, ask if the computer components are original, repaired or replaced.
4. Ask the seller if the machine is in full working condition. Some questions you might ask include a. does the machine power on and off properly; b. is the monitor clear without scratches or flaws; c. does the battery work properly; d. does the computer work properly without the battery installed and, if so, how long does the battery stay charged.
5. Determine what operating system is installed in the used laptop computer. The newest version of Windows, called Windows Vista, is not always compatible with all softwares. You will need to find out what operating system is running the computer and research if that operating system will run the software that you intend to install.
6. Find out what software is being included with the computer.
7. Thoroughly research competitive prices for the make, model and year of the used laptop computer that you are considering buying. This is easy to determine by reviewing the bids on similar products on Ebay.
8. If the machine is a fairly new machine, it might still be covered under warranty. If so, ask the seller if the warranty is transferrable to you upon purchase.
