Is your computer not recognizing your hard drive, or the BIOS not detecting the disk at all? Is your computer either the cable, or something behind your external hard drive not showing up anymore? Have a hard drive problem or you are not sure what is going on?
When you are no longer getting internal or external hard drive, the most important thing you have to do is diagnose the problem correctly. If you don’t know how to do this, then you want to look for an expert like SERT Data Recovery, someone who specializes in data recovery ON CH.
Case study: the hard drive is not visible in the computer
Customers reporting their external Western Digital My Passport were working fine the other day, but one day it was not recognized by the computer anymore. She plugged it in and plugged it in, and the computer admitted that something was plugged into the USB, but the drive didn’t show up. The light is already flashing and the drive looks good otherwise. The client had all the children’s pictures and financial information about their home business on the drive, so the client called us for a free consultation. We provide our customers with a shipping label and instructions on how to pack the drive safely. When we got the drive our engineer was able to identify it had in fact had a bad read / write head, and a firmware problem. This case required a stack assembly change from a donor and some procedure on our hard drive repair device.
The hard drive does not show the first response
Who is the first respondent to your emergency will determine the fate of your data. Spending too much time guessing, or performing inaccurate procedures can harm the hard drive, and make your situation much worse.
We’ll try to guide you and provide a basic foundation for you to understand the error messages you might get, but most of all know whether you need an expert or not. This applies to drives such as the My Passport USB or My Book – Western Digital external hard drive, or any internal / external laptop / desktop hard drive, that have problems detected.
Find out the differences, and similarities, between common errors, messages, and symptoms of an unrecognized hard drive:
- “The hard drive is not spinning”
- “External hard drive USB is not displayed”
- “External hard disk not detected”
- “Hard drive does not show up in the bios”
- “Hard drive is not included in disk management”
Perhaps you may have encountered one of these errors on your computer when you plugged in an external hard drive.
This information will help you (if the data is important, you should) when you contact a certified data recovery company to prevent the drive’s health from getting worse. This will cost you more money on hard drive recovery, and the drive may eventually reach an irreversible stage.
Steps to do with the external hard drive are not recognized or detected
This is a common error that you will get during normal operation when you plug an additional hard drive into your computer or laptop from within the operating system. This applies to both Apple and Windows platforms.
This error message is produced by one of the interface ports whether USB, Firewire, Thunderbolt, etc. and means: your computer has detected something plugged in, but cannot recognize any. any details about the device. This is one of the most common errors, because 90% of data recovered by the external drive will produce this same error, as long as the drive can get power.
Many hard drive malfunctions can cause this error, so it may be next to impossible to correctly diagnose it at this point. Fail or failure error, too many bad sectors, media (hard disk), corrupt file system, damaged mechanical or electrical parts can be the culprit.
What you do next may be a deciding factor in whether your data will be successfully recovered or not.
One common symptom we help our customers overcome when discussing their situation is the “WD external hard drive not recognized” . Western Digital It is well known that there are these types of problems. Most of the time the drive requires advanced technology to temporarily overcome the error and be able to view the drive’s data.
These data are often retrievable!
Sometimes the drive’s firmware must be repaired temporarily in order to gain access to the data, even if the drive can be detected. (Only one device on the planet can do this, and it’s very expensive.)
Basically when your external hard drive doesn’t appear, it might start spinning, and then it may appear to load the driver, but then it fails. The drive is still spinning and the light continues to blink.
Some other types of symptoms and sounds you may experience are: flashing, flashing, scratching, knocking, whirring, crushing.
In device manager / computer manager / disk manager, you might get an error saying:
- “The disc you inserted cannot be read by this computer”
- “The volume does not contain a recognized file system”
- “Unknown device”
- “You need to format the disk in the H: drive before you can use it”
- “USB device not recognized”
- “One of the USB devices attached to this computer is damaged”
- “The last USB device connected to the computer is damaged”
- “Windows doesn’t recognize it”
- “No media”
This is completely different from other types of hard drives. An example is when the hard drive is not detected, or found, by the operating system during boot. Simply the hard drive is not visible anywhere, no matter what you do.
Hard drive problems such as “hard drive not found”, “internal hard drive not found”, when your computer doesn’t detect the hard drive
Have you ever gotten the dreaded ” hard drive not detected ” error? You computer generated an alert that the hdd was not recognized, now what? This means you have an internal hard drive not found by the bios to find an operating system to boot from. Now you need to recover data!
When you start your computer and it cannot find the hard drive, it means it has failed. Sometimes it also says that the operating system cannot be found, select another disk in the computer. This is the typical case of hard drive failure.
When you have an internal hard drive or another type of SCSI, a SAS SATA hard drive not detected in the BIOS means there is a serious problem with the hard drive. Drives must be diagnosed to determine the cause behind the failure to detect.
It could be a cable, or it could be a head crash (when the head actually contacts the hard disk). Most of the time when the hard drive does not show up, it is the hard drive involved, and NOT computers or cables.
What causes a hard disk not to be detected or the bios not detected hard drive type of error?
The answer could be for a myriad of reasons. This is why it is absolutely necessary to choose a data recovery company that has the right equipment, and expertise, to determine the cause for hd failure.
This most important step, one that many computer and IT professionals overlook, can be the decisive factor in recovering your files in this situation.
Special equipment, which is very expensive and requires a highly skilled technician to operate it efficiently, is required in most types of data recovery cases.
Common causes are:
- Too many bad ingredients
- First failure or failure
- Corrupt firmware modules in the Service Area
- Electronics failed
- Engine failed
- Lack of muscle
- Damage Media (platter)
- Corrupt operating system (usually due to one of the above)
- The cable is bad
- No USB port
- Dropped drives
