This is a common query posted by many users on various technical forums, where they are trying to figure out why the external hard drive is not showing up on their computer after connecting.
This can be an annoying situation, especially when you?re on the clock and need to access critical data immediately. Here, you need to understand that an external hard drive is just another storage device that is prone to damage and corruption.
So, instead of worrying, you should dig deep and start applying various workarounds available to help you recover data from an undetectable storage drive.
Why is my External Hard Drive not Showing Up on the Computer?
There are numerous reasons that tend to make external hard drives undetectable by a computer. It could be anything from the following ?
- A sudden power surge that caused an unexpected system shutdown while the external hard drive was in use.
- Mishandling or dropping the external hard drive causing physical damage.
- Abrupt or improper system shutdown while the external hard drive is connected
- Virus/malware infection
- Prolonged or excessive use for extended durations
- External hard drive nearing the end of its lifecycle
- Bad sectors
- Outdated/corrupted drivers
- Unsupported file system
- Insufficient power supply
- Drive corruption causing the drive to appear as a RAW in Disk Management.
When an external hard drive is not recognized by your system, you will neither see it anywhere on your computer nor see any notification indicating a connected device.
Alternatively, you may also see a message, ?You need to Format disk Drive E: before you can use it. Do you want to format it now?? flash on the screen upon connecting the external hard drive.
Caution: If you see this message, don?t click the ?Format disk? button. This will wipe all the data on the drive, and you will lose all your data.

Now that you know why your external hard drive is not showing up, let?s try to fix this issue using the methods explained ahead.
Pre activity ?
Before moving on to the methods, try plugging the external hard drive into another USB port or another computer to see if there?s a problem with the port or the drive itself.

Method 1: Check for the External Hard Drive in the BIOS
Looking into BIOS is a great way to see if the connected external hard drive is being detected by the computer or not. Carefully follow the steps ?

- Locate the boot drive and see if the external hard drive is showing up.
- If it is displayed, then exit the BIOS and reboot your computer.
If your external hard drive is not showing up in the BIOS, it could be due to a faulty cable or loose connection. This could also happen if your external hard drive is uninitialized or unallocated. For this, move to the next solution.
