Spend 'a lot of money' to buy a PC, install all clean and clean programs, regularly block and scan viruses, master all the tricks to use the machine . but you probably forgot One of the most important principles: Every hardware has only a certain lifespan
'My hard drive is dead! '
What a bad news. Perhaps most people sometimes have to say this sentence when turning on the device but still only see the BIOS error message with the content that the hard drive does not exist. Calm down and start saving it.
First, determine if the hard drive (HDD) is still spinning? It is best to fully open the case cover and drop the headset correctly. If it still turns, you still have a chance.
Next, start the BIOS setup program (press delete or F2 button, F12 . depending on the model, right after starting the computer) and check if the BIOS still recognizes the device. Most will find that the BIOS settings have been changed - it may be interrupted by an error or the battery runs out of BIOS.
If the BIOS is still normal and the problem persists, try unplugging the device cables and plugging them in again. It may be in bad contact or if a cable is broken. Try taking the cable of another device (CD drive for example) to plug in the hard drive cable (only applicable with ATA hard drives using IDE cables, with SATA hard drives, you must buy another cable) to try it.
Instead of cables, the PC still can't boot and report a hard drive error, try removing it and installing it in another slot and see if anything changes. Sometimes the mainboard has a 'dead' phenomenon of a certain device slot. If you have just installed a new hardware, try removing it and checking whether the device is working because sometimes a hardware conflict error or the power supply of the machine is not enough to run a new device.
If you have removed some other hardware, including removing some unimportant expansion cards but the situation is still not resolved, it is likely that your hard drive will actually "go away". Prepare to make the last emergency method: freezing the hard drive.
Gently remove the hard drive from the machine, take a plastic bag that wraps it (preferably an additional one to cover the outside to prevent the hard drive from getting wet). Take care not to allow steam to enter the hard drive. Place the hard plastic covered hard drive in the refrigerator for several hours (about 2-3 hours) then remove and try to restart the machine. If that doesn't work, continue to do the same but put it in the freezer compartment.
This second chance is also very fragile but many people succeeded and hopefully you too. Remember, if after taking the hard drive out of the freezer it works again don't turn it off or reboot, you should quickly get all the necessary data out of the hard drive as it can "continue die "at any time.
Congratulations on retrieving your data, but please give your condolences now that you will have to buy a new hard drive.
