How to Recover Data from Undetected Seagate External Hard Drive ?

External hard drives are useful for storing backups or carrying large volumes of data when travelling. However, you can’t count on these devices a 100%. This is because a hard drive is mechanical which means that after years of usage, the inner components such as the read/write head and the magnetic platter that stores the data can go through a lot of wear and tear due to friction and eventually break down. Then there are virus attacks, human errors, and other risks that can also harm the device and the data.

Seagate hard drives, as reliable as they are, aren’t impervious to the common hard disk problems given above. So, if your computer doesn’t detect a Seagate external hard drive, then there can be many reasons behind that including:

Bad USB Port

If the USB port of the computer or laptop isn’t working, then it won’t detect your Seagate hard disk. If you are using a USB hub, then the problem could be with the USB hub itself.

Virus Infection

If you aren’t using a good antivirus program, then it’s possible for malware to attack your computer and the Seagate external hard drive.

Data Corruption

Sudden power outages or interruption during a data-transfer (possible if you accidentally disconnect the USB cable) can corrupt the data on the external hard drive and make the device inaccessible to the computer.

Physical Damage

The inside of a hard drive is like a record player. There is a read/write head (like a record needle) which writes the data on a magnetic platter (akin to a record). Just like a record player won’t work is the needle is misaligned, or the record is not set straight, a hard drive won’t work if the read/write head or the magnetic platter are damaged. Unfortunately, these parts are highly sensitive to jerks and physical impacts and break easily.

How to fix an Undetectable Seagate External Hard Drive

The following are some of the standard solutions for some of the common problems:

Solution 1: Use a Different USB Port

Try a different USB port for the hard drive. So, if you are using one on the front of the CPU cabinet, then you can try one in the back. However, even if then you aren’t able to access the Seagate external hard drive, then you can perform the below solution.

Solution 2: Reinstall the USB Driver

Sometimes, a computer doesn’t recognize an external hard disk drive because of a corrupted USB driver. However, you can easily uninstall and reinstall the same by following these simple steps:

Step 1: Go to “Start” and enter “Run” to locate and launch the “run” tool.

Step 2: Type “devmgmt.msc” and click “ok” which will open “Device Manager.”

Step 3: Find “Universal Serial Bus Controllers” in the list of devices displayed (it should be in the bottom half of the list) and click on the arrow icon to expand it further.

Step 4: Right-click the first USB controller and then select “Uninstall” from the options.

Step 5: Repeat the previous step for all the remaining USB controllers.

Step 6: Restart the computer after which the system will reinstall the USB drivers automatically, and check again.

Solution 3: Enable “Show Hidden Devices”

If your Seagate external hard drive is “hidden,” then it can’t be detected. However, you can easily change this by following these steps:

Step 1: Go to “Start” and enter “Run” to locate and launch the “run” tool.

Step 2: Type “devmgmt.msc” and click “ok” which will open “Device Manager.”

Step 3: Click “View” on the top and select “Show hidden ”

Step 4: If there are any greyed-out entries, right click and “Uninstall.”

Step 5: Restart the computer and try again.

Solution 4: Turn on USB Root Hub

Step 1: Go to “Start” and enter “Run” to locate and launch the “run” tool.

Step 2: Type “devmgmt.msc” and click “ok” which will open “Device Manager.”

Step 3: Right click on “USB Root Hub.” Select “properties” and then “power management.” Uncheck the option that says “Allow the computer to turn off this device to save power.”

Step 4: Repeat the uncheck method for all the remaining USB Root Hubs (if there are any).

Step 5: Restart the computer and try again.

Software Solution For Seagate Hard Drive Recovery

For logical errors, i.e., errors because of data corruption or malware, you can use a specialized data recovery software.

If the problem is not because of a logical error but the hardware, then the only way you can get a successful Seagate Hard Drive Recovery is with a “service solution” that is explained below.

Service Solution For Seagate Hard Drive Recovery

In a service solution, the hard disk drive is disassembled in class 100 clean room lab for a safe Recovery especially for the hard drive (all kind of make and models). This is because inside a clean room there is a controlled environment with less than 100 particles larger than 0.5 microns in each cubic foot of airspace as opposed to 35,000,000 particles in any standard space within an office.

In addition to that, the device itself is handled by data recovery experts who deploy complex recovery tools on the hard disk to ensure that you get back 100% of the lost data.
