Understanding Why Your Hard Drive Is Not Being Detected or Not Showing Up Anymore

There are many different reasons a hard drive may not show up NORMALLY ON your computer.

If this happened to you, and the data on your device is important, there are a few things you should know in order to have the best chances of getting it back.

This video is mostly to help those individuals with important data on their drive better understand their situation. This information is intended to help you learn the potential causes, and then know the proper procedure to safely get your data off that drive.

There are a few troubleshooting tips included in this video that may help you get back up and running quickly. However, if the data on your drive is worth $400 or more, this video will definitely help you make the right decisions in the process of recovering it.
When a drive is not recognized by your computer there are many things that could be the culprit.

However the reasons basically boil down to two categories:

1. Something very obvious and simple, or
2. Something seriously wrong with the hard drive that is going to require expert help. 

So our goal here is to basically help you quickly and safely troubleshoot the condition of your device, and figure out which category you are in.  

One thing to remember is that all hard drives fail eventually. Hard drives begin failing from the moment you power them up, and start writing data to the platters.
 
So don’t be surprised if your drive is in fact the problem. 
Many BRAND NEW hard drives come from the factory with errors on them. These errors come in the form of  failed sectors. Bad sectors are recorded and remapped in a part of the drive’s microcode which is usually written to the platter, called the service area. 

Inside the service area is microcode which are little software packets that contain data imperative to:

 regular function of the hard drive
 error reporting
 initialization data
 hard drive data
 bad sector rerouting
 encryption
 repairing the drive
 and many more

All of these packets are usually written to the actual platters themselves. Some manufacturers and drive models write copies on multiple platters, and some only on one under head 0 (or underneath the first platter on the bottom).

This helps the drive operate properly, and ensures stability during the reading/writing process, and overall function of the drive. 
If the heads cannot read this area(s), if there are damaged sectors, scratches on the surface, if it is corrupted, or overwritten without a backup the data will not be accessible.

If enough of the service area data is destroyed, or remains inaccessible, it becomes impossible to recover the files from the hard disk.

When there are too many errors it will corrupt the firmware leaving it in an unrecognizable state. This isn’t the case when it comes to Flash storage media like flash drives, SSD, camera cards. They have their own issues when they are not being recognized by the computer, however it’s usually due to failure or corruption of the device’s controller chip.
