When I try to access my 2Tb Transcend StoreJet External Hard Drive in Finder, I always get the following error:

enter image description here

However, 16Gb USB Flash Drive can be accessed without any problems.

I cannot also see any obvious reasons for that looking at disk info:

Running First Aid with Disk Utility and restarting Finder didn't solve the issue.
masOS version is High Sierra 10.13.2. Also there is no problem to access this HDD_2Tb drive on Windows OS.

Here is the output from Terminal:

# ls -lt /Volumes/
total 320
lrwxr-xr-x  1 root      wheel          1 Dec 13 19:21 Macintosh HD -> /
drwxr-xr-x+ 3 root      wheel         96 Oct 23 22:40 Preboot
drwxrwxrwx  1 _unknown  _unknown  131072 Jan  1  1980 HDD_2Tb
drwxrwxrwx  1 _unknown  _unknown   32768 Jan  1  1980 USB_16Gb

Any suggestions are welcome.

  • Are you attempting to access/save/recover data stored on the drive or do you just want to access the drive? – Allan Dec 17 '17 at 13:48
  • I'm trying to read the data stored on this drive or at least to see the filesystem tree. – DimaSan Dec 17 '17 at 13:50

    what do you get when do an ls -lt /Volumes/HDD_2Tb ? – Allan Dec 17 '17 at 14:23
  • Wow, it really shows the files on this drive! So the problem is probably with Finder? – DimaSan Dec 17 '17 at 14:29

    @Joe It at least cleared out any stuck processes etc. – nohillside Jan 21 '18 at 18:40

Just go to Apple menu then go to force quit then relaunch the Finder. It worked for me.

    Thanks, but relaunching Finder didn't work for me. – DimaSan Dec 20 '17 at 9:38

    What worked for me was holding "option" then right-clicking Finder on the dock, then clicking "relaunch". That worked like a charm. – kbpontius Jan 17 '18 at 20:18

I had the same issue.

Restarting with the hard drive mounted did the trick

Try the following:

  1. Unmount the drive
  2. Remove the icon from the Finder sidebar
  3. ls /Volumes to make sure that HDD_2Tb is not listed. If it is then reboot without the drive connected and check again. If it persists then rm /Volumes/HDD_2Tb making sure your drive isn't connected.
  4. Reboot with drive connected.
  5. Open a Finder window and right click on the title so you can navigate up to the machine level.
  6. You should see the drive, now double click on the icon.

That should flush all the required caches and allow the drive to remount properly.

  • The drive appeared in Finder after I run the long test from third-party app DriveDx and now I can read data from it, however that test did't find any errors. Thank you a lot for this advice, I will try it once it happens again. – DimaSan Dec 17 '17 at 23:22

Since the drive is mounting properly as evidenced by you seeing it in Terminal and in Disk Utility, your next step is to make sure that your Finder Preferences are set to show External Disks.

Go into Finder Preferences (Command,) then navitage to the Sidebar tab. Scroll down until you come to "External Disks" and make sure it's selected.

enter image description here

Next, eject the drive and delete the mounted folder if necessary.

$ sudo diskutil eject disk2
$ sudo rm /Volumes/HDD_2Tb

Then unplug the drive, verify that the mount and folder no longer exist, then plug the drive back in. This should cleanly mount everything again.

  • Thanks for suggestion Allan, but I had this checkbox to show external drives. – DimaSan Dec 20 '17 at 9:38
  • Does it show on the desktop? – Allan Dec 20 '17 at 9:40
  • Neither as well. – DimaSan Dec 20 '17 at 9:41
  • I placed a command in the comments of the question...run that and let me know what happens. – Allan Dec 20 '17 at 9:42

I had the same issue. I had formatted my pen drive and when formatted the disk changed into a alias file in the sidebar. Just remove the alias from the sidebar, then go to your home folder and you will find it over there.

If you have a similar problem like this.

and if you can actually list the mounted drive from the terminal like so:

MyMac:~ root# df

Then try to list content of the mounted volume:

MyMac:~ root# ls -lt /Volumes/SAMSUNG

-rwxr-xr-x  1 root  wheel      120  6 Dec  2013 Autorun.inf

and if any of the methods described in the linked issues does not work for you. Try to access the mounted volume directly in Finder like so

I was able to fix this by doing the following:

starting my mac in recovery mode by holding cmd + opt + r
selecting disk utility
clicking mount for my SSD
clicking first aid
restart my mac
