Prepare to fix problems like a pro; you can return to your important files with just a few clicks. The case of the unnamed external hard drive needs to be solved, so put on your detective hat, and let's begin!

How to Fix External Hard Drive Showing Untitled

Step 1: Check the Connections

If an untitled external hard drive isn't showing up on your Mac, the first thing you should do is ensure all physical links are safe. Separate the USB or Thunderbolt cord from the external hard drive and your Mac, and then connect them again. The hub may be giving you trouble. If that's the case, connect the drive straight to your Mac's USB port.

Step 2: Use Different Ports and Cables to Test

A broken USB port or cable can sometimes cause trouble. Use a different cord to connect the external hard drive to a USB or port on your Mac. It means there is a problem with the first port or cable if the drive shows up when attached through a different one.

Step 3: Check the Power Source

If your portable hard drive needs power from an outside source, like a desktop HDD, ensure it's plugged in and working. The drive might not work right if the power sources are broken. Try plugging the drive into a different wall outlet or using a different power charger.

Step 4: Check Disk Utility

Mac OS X has a Disk Utility tool that lets you control disks and volumes. To see if Disk Utility can see the unnamed external hard drive, do the following:

  • 1 > You can look for Disk Utility in Spotlight or go to Applications > Utilities to open it.
  • 2 > Look for the external hard drive in the list on the left. If it shows up but the volume is grayed out or marked as "untitled," there is a problem with the drive's file system.
  • 3 > Select the external hard drive to fix any disk problems, and then click the "First Aid" button.

Step 5: Format the drive

If Disk Utility sees the unnamed external hard drive but can't mount it, erasing it might fix the problem. But erasing the drive will eliminate all the data, so be careful and only do it if you have a backup.

  • 1 > In Disk Utility, find the external hard drive that doesn't have a name and click on it.
  • 2 > In Disk Utility, click the Erase button at the top.

  • 4 > Click Erase again to erase the drive.

Step 6: Clear NVRAM, PRAM, and SMC

On Mac, problems with connectivity can sometimes be fixed by clearing the non-volatile random-access memory (NVRAM) or parameter random-access memory (PRAM) and the system management controller (SMC). Press Command, Option, P, and R until you hear the Mac's starting sound again. It will clear both NVRAM and PRAM. To reset the SMC, turn off your Mac and press and hold the power button for 10 seconds. Then, let go of the button and turn the Mac back on.

Step 7: Check On A Different PC Or Mac

After following the steps above, if the unnamed external hard drive still doesn't appear on your Mac, connect it to either a Windows PC or another Mac. If it mounts correctly on another computer, the problem may be with the way your Mac is set up or the tools you're using. If you need more help, update your Mac OS to the latest version or call Apple Support.
