External Hard Drive is unlocated

Hi,

I've been browsing threads here to fix my external hard drive but unfortunately, no success at all. Every time I plug the hard drive, it is not showing in my PC, but it I can see that is plugged because it is showing in the "Safely Remove Hardware" section at the bottom right. I also tried the Mini Partition Wizard Tool but still I cannot resolve the issue. The tool cannot locate the hard drive.

It seems to have partitions but those are not shown in all cases. Try to run a chkdsk /r on it. Maybe it gets fixed.

Your unallocated drive needs a Partition letter.

Some tutorials by Brink that should help you. Please read all first.

Format a HDD or USB

Drive Letter - Add, Change, or Remove in Windows

Partition - Mark as Inactive

I tried the tutorials you povided ..still no luck
In the Computer Management, the drive is not listed. While in the command prompt, there is no volume for Data Back up or Removable Storage.

I think the screen print in post #1 is displaying info for the Internal HD (Disk 1), where Windows is installed.
I don't see a 2nd physical HD listed, for the External Drive.

Assuming the External HD is USB, i would try a different USB port.
If you're connected with USB3, can you try a USB2 port?

Can you connect this External HD to a different PC, and see if it has the same problem ?

Is this a new External HD, and nothing on it that needs to be saved ?
Or is it a new problem, and it worked before on this PC ?

For problems like this a proper Disk Management screen print helps:
Disk Management - Post a Screen Capture Image

I already tried to connect it to different ports and used other computers as well. There is a sound every time it is plugged but it is not showing in my PC.

If it's a new HD, i would RMA it and get a new HD.
If it's not new and has data you need, see if a data recovery expert can help.
