Symptoms
After the reinstallation of your Operating System, you notice that you can't find your data on the drive anymore.
What to do about them ?
It's most probably a partition problem and thus, a software problem. Don't format your HDD and don't try to reinstall the Operating System again, or you may lose your data definitively.
To recover your data, you must call a professional.
- do not format it
- do not put it in the fridge
- do not scratch the CD/DVD surface
- do not clean it with a corrosive product
When your CD stops working, it may be due to one of two types of failure: physical or software. In any case, don't try to repair it yourself. The more you tamper with it, the greater the likelihood of damaging the surface, and consequently losing your data irretrievably.
- Remove the key from your computer without closing the program
- Don't take to pieces the USB key on your own
- Don't format it
- Don't force the plug in the socket if there's any resistance
When your USB key doesn't work anymore, it can be two different kinds of breakdown, physical or software. At any rate, don't try to repair it by yourself. The more you try to repair it, the more you risk to damage irreversibly your data.
- 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.
- do not open it, you may damage some internal components
- do not format it, you may lose your data for good
- do not try to hit it on any side, you may phisically damage internal components
- do not try to turn it off and on many times, you may cause electric surge

Symptoms
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 about them ?
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.
Symptoms
If the disk falls, its surface or reading heads can be damaged. If the hard drive doesn't start, don't try to start it over and over because you may damage the disk more seriously.

If you hear a noise such as a jingle, the problem is probably involving the reading heads. If you don't hear any noise, but your drive don't start due to a fall, it may be another physical problem. At any rate, bring it quickly to a professional and don't try to fix it yourself.
Symptoms
