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 traveling. However, you can’t count on these devices a 100%. This is because a hard drive is a mechanical device which means that after years of usage, the inner parts 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 break down. 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 you have Undetected 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 it could be with the USB hub itself.

If you aren’t using a good antivirus, then your  Seagate external hard drive can be affected easily.

Data Corruption

Sudden power outages 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.

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. These parts are sensitive to jerks and physical impacts and break easily.
