  • put your hard drive in the fridge. It may bring dampness into it.
  • hit the disk on the side or on the top. You may damage the reading heads and the platters.
  • open the hard drive by your own. Open the disk in a non-sterile environment may bring some particles into the disk and damage the platters' surface.
  • in case of shock, don't try to fix it yourself, you may damage the disk. Appeal to a professional !
In general, when the disk isn't functional anymore, the more you try to use it, the more you risk breaking it definitively. As the reading heads are sliding about 7 nanometers over the platters, any shock or any dust particle could severly damage the platters' surface, making the data impossible to read.

A noise such as a jingle, « clac-clac-clac », shrill noise, or a dull sound are probably due to a physical problem involving the reading heads.
This noise is typical of a reading head's problem. Either one or more heads are defetcive and can't read the disk, or the platter's surface is damaged, so the reading heads can't read it.

What to do ?
If your hard drive makes that kind of noises, you're facing a big problem that you won't be able to solve on your own. Don't use your hard drive and bring it to a specialist who will be able to deal with the problem.

To access the BIOS, press F2 or F9 or F12 or DEL, etc. You will then see if it's detected or not.
When it doesn't appear in the BIOS, it can be a firmware problem, a connector problem, a System Area problem or the surface of the platters is damaged.

What to do ?
Check if all the connectors are correctly plugged. If not, plug your HDD on another computer and if your hard drive is still not detected, You're facing a serious physical problem. You should then contact a specialist.

If Windows seems to start but stops while the starting process, it may mean that you're facing a hard drive problem involving a defective platters' surface.

What to do ?
You should ask a data recovery specialist to repair the defective device in order to repair and recover the data with the other functional HDDs.

The JBOD system is an aggregate of a few HDDs. Unlike the RAID 0 system, the data is written on the first HDD. Then, when the first one is full, the data is written on the second HDD. And so on.

What to do ?
If the defective HDD doesn't contain any data and the JBOD system is built with two HDDs, you should be able to plug the first HDD on a computer and recover your data.
Should the opposite occur, you should ask a data recovery specialist to repair the defective device in order to repair and recover the data with the other functional HDDs.

With a RAID 1 system, all the HDDs are like mirrors of the others.

What to do ?
If all the HDDs are defective, you should ask a data recovery specialist to repair the defective device in order to repair and recover the data with the other functional HDDs.
