Tale of a desktop PC’s dead hard disk drive and how to replace one with a cheaper laptop hard drive
Owner whose PC has a dead hard disk drive: When I switch my desktop PC on a message appears that says that there is no operating system. I can hear the CPU making a noise. My PC is 9 years old. How can I fix it?
Open the PC’s case to find out where the noise is coming from. The hard disk drive in a desktop ATX case is in a drive bay that can hold several drives, including CD/DVD drives. In a laptop PC, the hard drive is usually in its own bay. A desktop hard drive looks like this:
PC owner: Yes, the noise is coming from the dead hard disk drive.
Reply: Your PC is 9 years old, but it could have a relatively new hard drive that is still under warranty. Some manufacturers give warranties up to 5 years. If it is under warranty, send it back to its manufacturer for repairs. If not, you have to buy a new or second-hand replacement. You are lucky it lasted for 9 years if the dead hard disk drive is the original drive.
IDE PATA or SATA hard drive?
Your PC is old enough to have an old-style IDE PATA hard drive, which uses a Molex connector from the power supply unit and a wide ribbon data cable that can usually connect two IDE hard disk or CD/DVD drives, configured as master or slave drives.
However, your PC probably has an SATA hard drive that uses thin, power and data cables. If that is the case, you can buy any SATA hard drive as a replacement, because the SATA standard of 9 years ago is backward-compatible with the current SATA standard.
Note that cheap converter cables are available that convert an old-style Molex power cable into an SATA power cable.
Remove dead hard disk drive and install the replacement drive
Here is an image showing an installed SATA hard disk drive, showing the power and data cables attached to the drive and the data cable attached to the motherboard.
PC owner: Yes, my PC’s drive has those cables, but what are those white things on the bays? My case just has holes for screws.
Reply: Those are mechanisms that fix the drive into the bay when engaged. You don’t use screws in that case.
The view, below, shows the drive sliding into the bay before the mechanism is engaged.
In your case, remove both side panels of the case, usually by removing four screws at the back. Consult the case’s user manual on how to open it if you have an exotic case. Next, detach the power and data cable, remove the two screws on each side that hold the drive in the bay and slide the drive out of the bay. When you get a new drive, just reverse the procedure.
Restore a recent backup or system image or clean install Windows on to the hard drive
Of course, to get up and running again, you will have to restore a backup or system image on to the new drive or clean install Windows or whichever operating system you use.
Use a 3.5-inch caddy and install a cheaper 2.5-inch SATA laptop hard drive
Note that high-capacity laptop hard drives are usually less expensive than desktop hard drives. You can buy a caddy that allows you to install one or even two SATA laptop hard drives in the 3.5-inch desktop-PC bay. The image below shows an inexpensive Inateck caddy that can hold two 2.5-inch SATA laptop drives. An excellent way to save money and case space in a workstation that doesn’t require a high-performance hard disk or SSD drive.
As you can see, the standard desktop SATA power cables (left) and data cables (right) fit a 2.5-inch laptop hard drive.
